Abstract
Heavy metal contamination in water and various food resources has raised concerns about the human health and well-being. Therefore, the purpose of the present study was to determine the physicochemical parameters and the levels of minerals and heavy metals in honey along with special implication of health risk assessment in Haryana, India. All the physic-chemical parameters were estimated by standard methods. All the minerals and heavy metals were analysed by Inductively Coupled Plasma-Optic Emission Spectrophotometer (ICP-OES). Results showed that the pH, moisture content, electrical conductivity, optical density, total protein content and acidity were 5.78, 20.89%, 0.81 mS/cm, 0.25, 0.00, and 0.21%, respectively. The mean values of minerals were 13.21 mg/100 g for sodium; 177.52 mg/100 g for potassium; 20.26 mg/100 g for calcium and 71.10 mg/100 g for magnesium. Among heavy metals, iron was most abundant with an average of 1.69 mg/100 g. The mean concentrations of selenium and copper in investigated honey samples were 0.68 mg/100g and 1.50 mg/100 g, respectively. Non-carcinogenic risk related parameters like estimated daily intake (EDI) and hazard quotient (HQ) were also analysed. HQ level indicated that there is a potential threat to children and adult population due to honey consumption in future. Our findings could lead to the need for future research, emphasizing the importance of exploring sources of heavy metals and implementing strategies to mitigate heavy metal contamination in honey.

Abstract
Isolation of Penicillium expansum from diseased pear fruits and their sensitivity were evaluated and identified as resistant and sensitive. Further research involved the utilization of susceptible Penicillium expansum isolates. Sensitive isolate (Pe-11) conidia of Penicillium expansum were subjected to thiophanate methyl and application of various physical mutagenic treatments, including spontaneous mutation (Sp), UV lamp, and chemical mutagens such as Bromyl Uracil (BU), Ethyl Methane Sulphonate (EMS), and N-Nitro-N-Methyl Urea (NMU), to the sensitive isolate of Penicillium expansum (Pe-11) revealed the emergence of mutants with varying resistance levels. Among them, highly resistant mutants demonstrated exceptional virulence, while moderately resistant and less resistant mutants also exhibited degrees of virulence. It was observed that UV ray treatment yielded a fruitful percentage of mutants, followed by SP, NMU, and EMS. The study concentrated on formulating fungicide resistance in resistant and sensitive isolates, emphasizing spontaneous mutation, UV, BU, EMS, and NMU. This investigation indicated a notable rise in the frequency percentage and a greater number of mutants compared to alternative treatments. Furthermore, the highest pathogenicity was attributed to mutants obtained via spontaneous, UV, and EMS treatment.

Abstract
A study was conducted to examine the impact of certain fungicides on the mycoflora of seeds and their effect on germination, vigour index, and persistence in treated groundnut seeds. In vitro seed treatment using chemicals was found to be a safe, cost-effective and highly efficient method for controlling seed-borne pathogens. In light of this, the current research aimed to assess the effectiveness of six seed dressing fungicides in terms of their impact on seed mycoflora and seed germination and vigour index of groundnut. Cv. TLG-45 shows the response to the captafol treatment concerning its seed mycoflora, seed germination and vigour index. Through careful analysis, it was observed that higher concentrations of carbendazim led to a reduction in seed mycoflora while simultaneously promoting increased seed germination and vigour index. The effect of captafol fungicides was observed on seed mycoflora, seed germination, and vigour index of Groundnut. The fungicide used for seed treatment was captafol, ranging from 0.1-0.5% concentrations. The captafol was found to be inhibitory to significantly reducing the percent seed mycoflora and increasing percent seed germination and vigour index.

Abstract
Boesemani Rainbowfish is one of the most popular ornamental fishes in international ornamental fish trade as well as in India due to its attractive color pattern, shape and ability to live in confined environment. This fish species is endemic to Lake Ayamaru and surrounding tributaries of West Papua, Indonesia and is used to being imported to India for ornamental fish markets. Due to high market price, this fish species still is out of reach to general fish hobbyists in India. The main reasons behind high market price are low supply and high import cost. Captive culture of this fish species can solve the problem of low supply as well also cut down the market price by curbing the import cost. With this aim, the present experiment was conducted to standardize the captive culture of Boesemani Rainbowfish in Indian climatic condition. Captive culture was done using sex ratio of 1:1 and stocking group of 40 individuals in the breeding tank. Important parameters related to captive culture like fertilization rate, hatching rate and larval survivability were measured. Fertilization rate, hatching rate and larval survivability was found to be 90.21%, 84.58% and 60.31% respectively.

Abstract
The fossil fuels, coal and natural gases are used as energy sources for automobiles. These energy sources are not eco-friendly, non-renewable, and they could exhaust in near future. This energy crisis, repercussions and hazardous effects associated with fossil fuels necessitate discovering of novel idea of alternative, ecofriendly and renewable energy sources. Bio ethanol is an alternative renewable energy source made from various agricultural waste products by the fermentation activity of yeast. This work is an attempt to produce bio ethanol from sugarcane bagasse agro waste using highly potent sugarcane bagasse saccharifying fungus Aspergillus niger and potent fermentative yeast Saccharomyces cerevisiae. For high bioethanol yield, the fermentation parameters including substrate concentration, incubation time, incubation temperature and pH were optimized. The potassium dichromate method was used to determine the amount of bioethanol separated through fractional distillation and was confirmed by GC-MS analysis. It was found that 2.5g/100 ml concentration of sugarcane bagasse with pH of 5.5 after being incubated for 10 days at 30°C showed high yield of bioethanol. It was estimated to be 6.81 % (v/v) at optimum conditions. It was confirmed by GC-MS analysis which showed 9.99% (v/v) ethanol at the retention time 20.08 minutes and the peak value 207 indicates highest ethanol concentration. This study revealed that sugarcane bagasse is one of the cheap and abundantly available agricultural waste can be exploited for the production of bioethanol since it contains significant amount of sugar.

Abstract
Microorganisms are ubiquitous and plays important role for maintaining the nutritive value of soil. Soil microbes are part of soil biological as well as organic matter, responsible for releasing nutrients from organic matter or convert them into more easily accessible form by the plants. The application of chemical fertilizers leads to decrease in microbial flora and fertility of soil. Therefore, it is necessary to explore substitutes to increase the efficiency and quality of crops with minimal environmental impact. The use of plant growth-promoting bacteria can provide solutions to some agri-environmental problems. In this study, Soil samples are collected from different region of Jalgaon area such as “Meharune Pimprala and Paldhi. Two bacterial strains of nitrogen fixing, phosphate solubilizing and potassium solubilizing are isolated and tested for growth promoting ability. Further on basis of biochemical characteristic, the isolated microorganism are identified with the help of ABIS online platform. The isolated organisms are identified as M1D1(Bacillus megaterium), M1B1 (Pseudomonas fluorescens), M2B2 (Bacillus bataviensis), M2C1 (Bacillus tequilensis), M3D2 (Azotobacter chroococcum) and M3B1 (Azotobacter beijerinckii). The results, in vivo, demonstrate that the bacteria increase the length of root and shoot with the number of leaves. The outcome implies that Bacillus tequilensis has properties as a plant growth promoter and can be used as a promising inoculant to enhance the growth of seedlings.

Abstract
A cropping pattern refers to the proportionate area under different crops during an agricultural year. An area's agricultural transformation is mostly determined by the cropping pattern, so studying it is vital. The present research work attempts to study the trends and fluctuations in the area under important crops in the arid agroclimatic zone of south-west Haryana by using space-borne remote sensing data by unsupervised classification in ERDAS IMAGINE 2014 software along with secondary data. The study was conducted over three time frames, viz., 2000, 2010 and 2020. Analysis of cropping patterns in the study area revealed that rice, cotton and mustard crops have come to dominate, and the gram area has declined. Rice and cotton have increased due to fertilizer and irrigation by groundwater and canals. The area under gram has decreased and been replaced by mustard in some places. The study presented the spatial distribution of the present cropping pattern in the south-west parts of Haryana.

Abstract
Plant diseases are one of the main causes of obstruction in plant production, which can lead to the deficiency of food supply worldwide. It is recommended to diagnose plant diseases at their initial phase to reduce agriculture loss. So, there is an urgent need for markedly improved detection, monitoring, and detection of plant diseases. The primary emphasis of this research is to design a novel hybrid model to categorize potato leaf diseases at their earliest with the deep convolutional network by assessing leaf images. This proposed work is based on image feature extraction to train and test the proposed hybrid model. The dataset of 1200 potato leaf images were extracted from the Plant-Village dataset for leaf disease detection. The proposed system for leaf disease detection produced an enhanced training accuracy of 98.60% while training loss reduced to 0.0394 after 25 epochs. The proposed system will be beneficial for the farmers to diagnose leaf diseases at their earliest by evading manual identification which is a very tiresome and labor-intensive task.

Abstract
Contemporary apprehensions about environmental degradation stem from various natural and anthropogenic activities, encompassing rapid industrialization, global economic expansion, increased agrochemical use, and increased hydrocarbon deposition. This multifaceted array of activities contributes to environmental decay, resulting in decreased crop yields and deleterious effects on the biota. Heavy metals emerge as prominent contaminants in environmental pollution, characterized by their nonbiodegradable nature and prolonged persistence in ecosystems. The deleterious repercussions of heavy metal contamination on soil and aquatic organisms are multiple, thereby necessitating vigilant consideration. The adverse consequences of heavy metal exposure extend beyond the environmental impact to include significant implications for human health. Consequently, remedial interventions become imperative to eliminate hazardous organic heavy metals or facilitate their conversion into less harmful inorganic forms. This review synthesizes the existing literature on the intricate interplay between anthropogenic activities, heavy metal contamination, and the resulting environmental and health implications. By scrutinizing these intricate dynamics, this review seeks to illuminate the imperatives of effective remediation strategies in mitigating the adverse consequences of heavy metal pollution, thus fostering sustainable environmental practices and protecting public health.

Abstract
Groundwater is a vital life component in earth for sustaining every species of life. Groundwater is incredible source through water cycle and it is extremely beneficial for the living body. But, the not potable water release from geogenic sources and some place anthropogenic source may significantly levels of pollution in groundwater, making it vital to assess the quality of the groundwater for current use and to develop its potential as a sustainable water source for human use. Groundwater is a major source of irrigation and drinking water in India's rural areas. The condition of ground water is very important in this part of Harur Taluka since it is a vital source for agriculture and drinking water, and the local population faces numerous problems with water quality. The goal of the irrigational purposes of current study project is to look into the geographical distribution and quality of groundwater. approaches as well as hydro chemical dynamics. pH of groundwater samples are fall in potable condition their limiting Values of 6.5 - 8.5 in this study area. In this research work, twelve water quality parameters were tested at 34 different selected locations, including E.C. micS/cm, TDS, pH, Na+, K+, Ca2+, Mg2+, HCO3, CO3, SO4, Cl, and F. The purpose of the analysis was to evaluate the quality of the water. Every region within the study area is classified as Acceptable, Allowable, and Not Potable based on the spatial distribution map. The hydro chemical mechanism of water quality was principally due to the leaching from soil to groundwater. Groundwater in the studied area has a geochemical pattern that indicates sodium as the predominant cation (NaCa Mg>K) and chloride as the predominant anion. (CI>HCO3>SO4>H4SiO4>NO3>F>PO4) respectively.

Abstract
The common salt is the major source of sodium to the diet. Excessive salt intake has various negative effects on health. Pickle is the product containing high amount of salt. The aim of this work was to reduce sodium content and to study the effect of sodium chloride replacement with potassium chloride on physiochemical, sensorial and microbiological qualities of mango pickle during storage at room temperature (25±5°C) in glass jar and laminated foil pouch. From sensory analysis as insignificant differences were observed in overall acceptability score of pickles made by replacing 25% and 50% of sodium chloride with potassium chloride (8.17 and 8.14) compared with control (8.18) the pickle made with maximum 50% potassium chloride in replacement of sodium chloride was considered for further physicochemical, sensorial and microbial study during storage. No significant difference among proximate constituents was observed in control and selected potassium salt replaced sample (MPK2). The overall acceptability of MPK2 was found about 8.53 in glass jar and 7.02 in laminated foil pouch up to 9 and 7 months respectively. The moisture content, water activity and titrable acidity of MPK2 were found to be increased while pH was decreased during storage in both packaging materials. The sample found microbiologically safe up to 9 months and 7 months. Thus, it was possible to reduce the sodium content of mango pickle by replacing 50% sodium chloride with potassium chloride and could be stored safely up to 9 months and 7 months in glass jar and laminated foil pouch respectively.

Abstract
In India, white grubs have recently become a more challenging pest. The white grubs are sometimes known as May-June beetles or Chaffer beetles. White grubs consume plant roots, and their beetles consume the leaves of their hosts. The extent of their infestation has been widely publicized over the past few years, with reports coming from all around the nation. Because of the inability to manage their damages, most farming operations have essentially abandoned efforts to control these pests. The Indian state of Maharashtra includes Jalna. Holotrachia consaguinea Bl., Holotrachia longipennis Fab., Holotrachia rosettae Br., Leucopholis lepidophora Bl. (Melolonthidae), and Anomola sp. (Rutelidae) are the five main species of white grubs, particularly in Maharashtra. Scarabaeidae adults were gathered for the current study from the leaves of host plants including Citrus limetta, Saccharum officinarum, Sugar cane, and pigeon pea. The Holotrachia longipennis is the most prevalent species in Jalna, a city in the Indian state of (Maharashtra). Research efforts have focused on studying these pests and their impact on various host plants such as Citrus limetta, Saccharum officinarum (sugarcane), and pigeon pea. Understanding the behavior and biology of these pests is crucial for developing effective management strategies to mitigate their damage and protect agricultural yields in affected areas like Maharashtra.

Abstract
In this paper, study is mainly soil quality profile of lateritic soil since Southern part of Karnataka and Kerala is mainly varied with red soil and lateritic soil and also has major production of cash crops like coconut, areca-nut and rubber. Agriculture is an important enterprise of Kasaragod district Kerala, India. For the collected soil sample, basic soil tests such as moisture content, bulk density, grain size analysis and physicochemical parameters like pH, electrical conductivity, macronutrients organic carbon, nitrogen, phosphorus and potassium were performed and results were calculated. The secondary nutrients like calcium and magnesium content of soil are analyzed. Results were interpreted from the spatial variation maps. The soil texture of the soil in the Padre micro watershed area is of sandy clay with very less percentage of silt. The percentage clay in soil ranges from 28% to 63%. Clay level will influence the behaviour of organic and inorganic pollutants in soil. The nature of the soil is acidic in pre-monsoon and post-monsoon. Generally, this characteristic feature is very common in lateritic soils. It is observed that organic content in the study area is in the range of 0.06 to 3.36% during the pre-monsoon season, and the values range of 0.1 to 3.8% during the post-monsoon season. Increased soil organic carbon and exchangeable bases are influenced by the vegetation, climate, altitude, and soil minerals, respectively. Another potential cause of the soil's pH being lowered is the existence of a larger concentration of organic materials. The decreased value of total nitrogen in organic plots may be due to crop uptake, microbial immobilization, and volatilization.

Abstract
Soil analysis is usually carried out to check soil quality, nutrient content, and changes in various soil parameters and thus provide all the information necessary to understand the nutrient inputs needed to improve the soil. To achieve the expected yields, it is essential to understand the quality of the soil in advance. Soil may be tested for nutrient content, moisture content, texture, and pH amongst other factors to procure more information. It changes its properties with respect to the environment. Soil reflects both natural and human activities. It turns its properties into ecological problems. Two desirable functions of healthy soil are nutrient cycling and insect suppression. Insects can affect soil and plant health directly by feeding on pests or serving as alternative prey for larger predatory arthropods. In this study, soil quality such as pH, electrical conductivity (EC), nitrogen, phosphorus, potassium, iron, zinc, manganese and chromium were measured in sediment samples from Sirumalai hill. The results show that the soil contains enough organic carbon and nutrients for the growth of microbes and plants.

Abstract
The purpose of this study is to empirically analyze the factors that affects India’s agricultural exports and identify the potential in agricultural exports with South Asian Association for Regional Cooperation (SAARC) economies. Presents analysis utilizing various specifications of an augmented gravity model of trade, incorporating both time-invariant and time-varying factors collected from secondary sources for the period of 32 years from 1990 to 2021. The coefficient obtained from the gravity model of trade is subsequently employed to calculate the speed of convergence in order to ascertain the export potential of India with SAARC economies. The findings demonstrate that the majority of the variables display the anticipated sign and are statistically significant, thereby confirming the principle of the gravity model of trade. Moreover, the rate of convergence reflects that India has demonstrated convergence in agricultural exports with five SAARC members, specifically Bangladesh, Bhutan, Nepal, Pakistan, and Sri Lanka, while experiencing divergence with Maldives. Thus, the study suggests that India possesses substantial untapped potential for agricultural exports with SAARC economies, which must be harnessed by expanding its agricultural exports portfolio.

Abstract
Plant-derived compounds, known for their safety and non-toxic attributes, are increasingly sought after in the pursuit of effective anticancer agents. This study aimed to elucidate the in-vitro anticancer potential of ethanol extract from Allium fistulosum against the human breast adenocarcinoma cell line (MCF-7) by inducing apoptosis. The cytotoxicity against MCF-7 was evaluated using the MTT assay. The apoptotic effect of the ethanol extract was characterized through mitochondrial membrane potential (MMP) analysis, reactive oxygen species (ROS) assay, and Acridine Orange-Ethidium bromide staining method. The MTT assay revealed concentration-dependent cytotoxicity, with IC50 values measured at 45.85 μg/ml, while demonstrating minimal toxicity against normal endothelial cells. Furthermore, treatment with the ethanol extract induced a reduction in MMP and an increase in ROS levels within breast cancer cells. These findings suggest that the ethanol extract may possess potent anticancer and apoptogenic activities by inducing mitochondrial dysfunction and oxidative stress damage in breast cancer cells.

Abstract
The current study attempts to understand the demographic variables and their influence on cotton's marketing problems in three Telangana state districts. These three districts are located in three agroclimatic zones, i.e. Adilabad (NT Zone), Warangal (CT Zone) and Mahabubnagar (ST Zone). The study is based on primary and secondary data collected during the agricultural years 2021-22. Secondary data was collected from the agricultural marketing board, CCI, Telangana State Agricultural Department. Data is processed using descriptive analytical tools and techniques. Most of the farmers, 170 (37.8%), have 11-15 years of experience, followed by 6-10 years (18.9%) and 16-25 years (17.3%), and the farmers with less than five years of experience in farming account for 11.1%. The farmers with more than 25 years of experience are showing interest in cultivating the cotton crop, accounting for 14.9%. Most of the farmers 139 (30.9%) have invested in cotton crop production below one lakh, followed by 2-4 lakhs 117 (26%). Only farmers could invest more than ten lakhs, numbered 41 (9.1%). Most of the farmers are cultivating cotton in an area of less than two acres of land 177 (39.3%), followed by 2-5 acres of land holdings 125 (27.8%) and 5-10 acres holdings 73 (16.2%). The cotton-growing farmers with over 20 acres of land holdings are about 20 (4%). It is also observed that newspapers ranked first among the three impersonal sources of cotton marketing information, followed by radio and television. In contrast, the market committee ranked first out of the six formal personal sources of information, followed by CCI and e-NAM. The data from the informal personal sources of information (nine sources) revealed that cooperative marketing occupied first rank, followed by progressive farmers, relatives, cotton grower associations, farmer's friends, neighbours, trading companies, and commission agents.

Abstract
The majority of plants have therapeutic qualities that are frequently used by native people throughout the world. Research focuses on describing and evaluating plant components potential for fighting various illnesses; however, it is still difficult to recognize bioactive components. Asia's tropical and subtropical climates are native to Lagerstroemia speciosa. The sample plant we used has two different leaf types: a green leaf and a red leaf. The leaf pigments exhibit the colour variation. Focusing on a wide range of phytopharmacological characteristics and GC-MS investigations is something we're interested in. Finding the active compounds that were separated from the ethanol extracts of L. speciosa leaves was the objective of the study’s earlier work. The pharmacological properties include antimicrobial, antioxidant, anticancer, antidiabetic, hypolipidemic, anti-obesity, anti-inflammatory, analgesic, gastrointestinal, diuretic, thrombolytic, cardiovascular, central nervous, inhibition of TNFα production, xanthine oxidase inhibition, hepatoprotective and nephroprotective effects. The chemical constituents, pharmacological effects and therapeutic effects of the selected parts of L. speciosa are discussed in this study.

Abstract
Azolla is as fastest growing aquatic fern widely found in stagnant water bodies and have lots of research and economical value due to its symbiotic association with cyanobacteria. The purpose of this research was to observe the effect LEDs red, blue and white light as control on growth rate, antioxidant capacity and symbiotic association of Azolla caroliniana. Under the experiment light intensity was standardized with 58 µmol m−2 s−1. The results showed that red light shows the highest effect on growth rate of fern. The antioxidant activity was measured by the radical scavenging test (DPPH), Ascorbate Peroxidase (APx) and Superoxidase dismutase (SOD). DPPH and Ascorbate Peroxidase (APx) showed the highest activity under the red-light treatment therefore utilized in pharmacological application. Apart, the research was also carried out to study the effect of light on symbiotic association and ultrastructure of fern. Based on confocal Imaging analysis data, it is revealed that exposure to red and blue light stimulates the formation of pectin projections or teat cells. The possible role of the projections in the symbiotic relationship between Anabaena azollae provide additional evidence for providing defense role. The present result suggests that among all the light treatment, red light was most beneficial for growth and antioxidant capacity of fern.

Abstract
Farmer Producer Organizations (FPOs) are the institutional progeny of cooperative institutions. Emerging small and marginal landholdings encountered unique and complex problems and experienced intricacies in the existing support system, which the cooperatives could not address effectively. Thus, the FPOs emerged as a needed new institutional model to understand and remedy the issues of the farmers and agriculture system as a whole. India, China, Africa, and Europe have taken a lead role in promoting the FPOs for the welfare of farmers and the betterment of agriculture. Comprehensively, the studies on FPOs focus on various areas that are not properly researched and documented. Bibliometric analysis essentially caters to the needs of the researchers in identifying the themes of the studies conducted on the FPOs. The present study has selected 70 research papers on the FPOs and adopted bibliometric tools i.e. co-word, network, cluster, and thematic analysis. The study has identified the themes - smallholder, collective action, agricultural development, agricultural worker, commodity market, and supply chain management. The clusters that the studies are grouped are – smallholder, income, agricultural land, food supply, and livelihood. The themes and clusters identified from the studies indicate the evidence for future research and intervention.

Abstract
The escalating demographic pressure has multiplied the demand for agricultural commodities manifold. The changing environmental scenario and altered climatic conditions have affected agricultural production to a greater extent across the globe. Likewise, the availability of nutrition becomes a great challenge for humanity, - Rajasthan in India, is one such State that faces food and nutrition challenges. The present study focuses on the issue of food scarcity, agricultural production, and nutritional demand in the study area. The objectives of the study include analyzing the crop concentration and nutritional availability and human health in the study area. The crop production has been analyzed in the light of crop concentration index for various crops like pearl millet, jowar, maize, and wheat while nutritional demand has been analyzed in the light of food consumption or utilization. The parameters like underweight conditions and anemic conditions have been analyzed for children and adults (both men and women). The crop concentration index (CCI) has been calculated for mainly food grains jawar, bajra, wheat, and maize in order to understand the crop concentration scenario in the state of Rajasthan. The CCI was coupled with a correlation matrix and regression analysis model in order to analyze the impact of crop concentration on the health of people in the study area. The findings of the study show that though the nutritive value of crops like maize and jowar was high it resulted in iron deficiency among the people of the study area. In addition to this, women are more anemic as compared to their male counterparts in the study area. Similarly, maize and jowar dominant resulted in underweight conditions among the children in the study area. The study concludes with proper suggestions in order to bring agriculture on the lines of sustainability and to find alternative solutions to meet the iron deficiency in the study area. Lastly, the study also makes an appeal to agricultural experts, social scientists, health experts, and nutritionists to highlight such issues for the betterment and welfare of our country.

Abstract
Indebtedness is one of the most important causes of farmers’ distress in West Bengal. It also increases the burden of non-performing assets in financial institutions and leads to a serious problem of credit allocation. Lending operations entail a certain level of risk due to asymmetric information. The asymmetric information creates moral hazard problems in the agricultural credit market. The aim of the research work is to find out the responsible factors that can influence the repayment performance of the farmers and identify the moral hazard problem in some selected rural areas of the North 24 Parganas district of West Bengal. The logistic regression method was applied to over 300 borrower farmers in the selected study area to assess their repayment performance and identify moral hazard issues. The research identifies that moral hazard problems among farmers lead to credit repayment issues and adverse credit discipline. Diversification of credit for unproductive activities and the expectation of loan waiver scheme would be the main reasons for the moral hazard problem. Proper monitoring by the officials of the financial institutions for productive utilization of credit, along with an assessment of risk management, are the preconditions of good lending activities.

Abstract
Antibiotic resistance poses a serious global public health threat, necessitating the discovery of new antimicrobial agents. This study explores the antibacterial potential of Corymbia ptychocarpa, an ethnomedicinal Australian plant used in traditional medicine but not scientifically investigated. Phytochemical screening of leaf and stem extracts revealed a diversity of bioactive compounds like flavonoids, tannins, glycosides, and alkaloids with known antimicrobial properties. Gas chromatography-mass spectrometry (GC-MS) analysis identified major antibacterial, anti-inflammatory, and anticancer candidates in the leaf (ethyl acridine) and stem (indolizine). The extracts were tested against ESKAPE pathogens using disk diffusion assays. Both leaf and stem extracts exhibited promising antibacterial activity, with inhibition zone diameters ranging 2-7 mm compared to antibiotic controls. Leaf extracts showed broad spectrum inhibitory activity, especially against Klebsiella pneumoniae and Salmonella typhimurium. Stem extracts were most potent against E. coli and E. faecalis. The observed antibacterial effects validate the traditional use of C. ptychocarpa and reveals its potential for new antibiotic drug discovery.

Abstract
Natural dyes have, therefore, always played a significant role in human life. Although indigenous knowledge system has been practiced over the years in the past, the use of natural dyes has diminished over generations due to lack of documentation. Tectona grandis L., belongs to the family Lamiaceae is an important dye yielding plant in ancient times. Teak leaves can also aid in the treatment of inflammations, leprosy, skin diseases and indolent ulcers. Dyes are important in human life because they are both safe and environmentally friendly. The term macroscopic refers to substances that can be seen with the naked eye, whereas the term microscopic refers to substances that cannot be seen without the use of a magnifying device. It is possible to identify and localize biomolecules and organelles at the cellular level in various types of cells and tissues using histochemical techniques. Fluorescence is the emission of light by a substance that emits electromagnetic radiation. The results shows that the Tectona grandis leaves have dorsal and ventral surfaces that are 30-60cm long and 20-30cm wide. Teak leaf powder was treated with diluted ammonia and H2SO4 to produce a yellow colour, indicating the presence of flavonoids. A few drops of Fecl3 produced a black colour, indicating the presence of tannin. Blue, green or red coloration indicates the presence of polyphenol, while dinitrophenol hydrazine indicates the presence of terpenoids. Under both regular and UV light, the fluorescence behaviour of teak powder under various situations was investigated.

Abstract
The study of freshwater algae is really the study of organisms from many diverse habitats, some of which are not entirely “fresh.” Aquatic ecologists also use the term “inland” waters to encompass a greater range of aquatic ecosystems. Even this term may be unsatisfactory, because algae occupy many other habitats, such as snow, soils, cave walls, and symbiotic associations. Organisms grouped together in this volume as freshwater algae fall into a large, but ecologically meaningful collection of environments: all habitats that are at least slightly wet, other than oceans and estuaries. One reason for such a broad scope is that inland saline lakes, snow and ice, damp soils, and wetlands are studied by phycologists and ecologists who also examine more traditional freshwater environments. Some genera with terrestrial species, such as Vaucheria, Nostoc, Chlorella, and Prasiola, also have species found principally in streams or lakes. There are no exclusively freshwater divisions of algae, but certain groups exhibit greater abundance and diversity within fresh waters, especially Cyanobacteria, Chlorophyta, and Charophyta. Within the green algae, conjugating greens and desmids (Zygnematales) comprise a very rich collection of species that almost exclusively occupy fresh water. Other groups, such as the diatoms and chrysophytes, are well represented in both spheres. Other groups, particularly the Phaeophyta, Pyrrophyta and Rhodophyta exhibit greater diversity in marine waters. The present study revealed as, Chlorophyta and cyanophyta were the dominant groups.

Abstract
The need for food production is being driven by the world's expanding population. Meanwhile, conventional farming, which relies on soil-based methods, is unable to meet the world's growing food needs. Thus, developing novel planting and farming techniques is essential to averting further food crises. The purpose of this study was to investigate the hydroponics system, which is an effective alternative planting method. The growth, morphological, and biochemical characteristics of Triticum aestivum and Trigonella foenum-graecum were evaluated and compared between soil and hydroponic systems. It was noted that wheatgrass and fenugreek cultivated hydroponically have longer roots than plants grown on soil. In comparison to plants grown in soil, it is also shown improved growth in terms of plant height, leaf length, leaf breadth, and leaf area. It was discovered that plants grown in soil had higher levels of total chlorophyll than plants cultivated in hydroponic systems. The soil-grown plants exhibited a significantly higher total phenolic content and antioxidant activity in comparison to their hydroponic counterparts. The hydroponic system presents growers and customers with a plethora of new options and chances to produce crops of superior quality. Hydroponics is a viable alternative method for growing leafy vegetable seedlings.

Abstract
The silkworm Bombyx mori L. is a lepidopteran insect used as laboratory tool for various experiments. Being a domesticated insect it has been reared mainly for the production of silk. The successful production of the silk not only governed by dynamic environmental factors but also affected by quality of mulberry leaf provided to silkworm. Hence, dietary nutrients are the most important factor which determine quality and quantity of silk production. An experiment was carried out to know the impact of mulberry leaf fortified with amla juice at varied concentrations viz., 0.2, 0.4, and 0.6% on protein and carbohydrate contents as well as commercial parameters in the FC1 silkworm hybrid. The larvae reared on amla at 0.2% concentration registered higher protein and carbohydrate contents in the fat body and midgut tissue over absolute and distilled water control. However, carbohydrate and protein contents were relatively higher in the fat body when compared to midgut tissue in all the treatments. A similar trend was also observed at 0.2% concentration for commercial parameters such as larval weight, cocoon weight, shell weight, pupal weight, shell ratio, filament length, filament weight, denier, renditta and raw silk percentage.

Abstract
The impact of seed hydropriming, plant geometry and integrated nutrient management treatments on soil fertility and protein content and yield green gram crop was studied in field trials. Seed hydropriming resulted significant increase in grain yield of mung bean by 54.71% over untreated seeds. Plant spacing of 30x10 cm (treatment G1) witnessed 138.272% increased yield of 995.70 kg/ha over the treatment G2 (30 x 20 cm) yielding 417.88 kg/ha. The treatment N2(FYM equivalent to RDF) produced minimum yield of 617.49 kg/ha which was enhanced by 7.89%, 12.61%, 22.09%, and 29.71% due to N1(20:40:20 kg NPK/ha (RDF), N3 (Vermicompost equivalent to RDF), N4 (½ RDF + FYM equivalent to ½ RDF) and N5 (½ RDF + Vermicompost equivalent to ½ RDF), respectively. Minimum stover production of 912.25 kg/ha as a result of treatment N2 (FYM equivalent to RDF) was increased by 2.38%, 4.40%, 5.11%, and 6.43% due to treatments N3, N1, N4 and N5. Significantly more depletion of available N, P and K from soil was observed due to the treatment P2 (seed hydropriming) compared to P1 (untreated seeds). The plant geometry treatment G2 (30 × 20 cm) removed significantly more amount of available nutrients than G1 (30 × 10 cm) which caused more residual nutrients in soil at harvesting time. The removal of nitrogen was significantly more due to nutrient treatments of N5 > N4 > N1 > N3 > N2. The residual amount of available P and K in soil was due to treatments N3 > N2 > N1 > N4 > N5, indicating significantly more depletion of P and exchangeable K due to treatments of N5 > N4 > N1 > N2 > N3, respectively. The residual amount of nutrients had direct inverse relationship with the total production of grain and biomass of crop. Significantly high crude protein of 20.97% and protein yield of 180.84 kg/ha, respectively was due to treatment of P2 (seed hydropriming) compared to treatment P1 (untreated seeds). The treatment P1 recorded 20.33% protein in mung bean grains and protein yield of 113.21 kg/ha, respectively. The enhancement of protein content and protein yield due to seed hydropriming was 3.14% and 59.73%, respectively over untreated seeds. Significantly high protein (20.82%) and protein yield (208.19 kg/ha), respectively was due to treatment G1 and increase was 1.66% and 142.50%, respectively over the treatment G2. Nutrient management of N5 (½ RDF + Vermicompost equivalent to ½ RDF) led to significantly high of 20.81% protein and protein yield of 167.84 kg/ha, respectively. Next in order was the treatment N4 (½ RDF + FYM equivalent to ½ RDF) resulted 20.74% crude protein and protein yield of 157.38 kg/ha, being on par with N5. Results lead to conclude that seed hydropriming, 30 x 10 cm plant geometry and combined application of N5 (½ RDF + Vermicompost equivalent to ½ RDF) followed by N4 (½ RDF + FYM equivalent to ½ RDF) were assessed to enhance productivity of crop, quality of soil, protein per cent in seeds and protein yield significantly.

Abstract
An On Farm Trial was laid by KVK Shopian in collaboration with Division of Livestock Production Management, under Department of Bio Technology (India) funded project to workout feasibility and economic viability of integration of back yard poultry in apple orchards under the tag of Horti-Poultry Model. The average cost of production for High Density Apple orchard of 3 kannals is 4.5 Lakh. The net return in terms of Apple is 7.0 lakh. The Benefit cost ratio is 1.5:1. Adding Vanraja birds into the apple orchard of 3 kannals, the net returns from 150 birds had added Rs 1.43 lakh. The Benefit cost ratio had increased up to 1.8:1. The growth of plant trees was normal with zero percent mortality of trees and the yield percentage of the crop (apple) was increased by integration with Vanraja birds. The plant health parameters like leaf health were found normal without scab. The fruit setting and fruit health was also without any abnormality and disease. However, in later stages, it was observed that lower fruits were eaten by birds, so we can recommend that clonal apple trees should be pruned and trimmed so that branching starts above three feet. The density of birds in apple orchards was also observed to be a main factor for controlling the birds in damaging the trees, which should always be below 50 birds per kanal. It was observed that if only 50% of apple orchard area of district Shopian is brought under this IFS system, there would be 92 Crores flow of revenue in Shopian district only as there is around 21777 hectares of apple orchards.

Abstract
Pharmaceutical researchers are continually exploring potent compounds that could lead to the discovery of effective treatments against pathogens. Scientists maintain an unwavering interest in identifying effective molecules from the vast array of phytochemicals. In this study, we prepared hexane and acetone extracts from the medicinal herb Andrographis paniculata. These extracts were screened against the pathogens E. coli, S. aureus, and P. aeruginosa. Interestingly, the hexane extract exhibited no activity against the pathogens, while the acetone extract demonstrated significant inhibitory effects on the growth of all three pathogens. To identify the specific phytochemicals, present in the extract, we conducted GC-MS analysis. Among the compounds identified, three stood out due to their favorable ADME properties and bioavailability: alpha-bisabolene epoxide, alpha-bulnesene, and andrographolide. Further investigations involved in silico studies on selected structural proteins of microbes with these drug-like molecules. These studies revealed that andrographolide, a diterpene lactone, exhibited high binding affinity on the structural receptors of pathogens. Additionally, computational methods were employed to identify the most likely receptor involved in inhibiting the growth of microorganisms.

Abstract
An investigation has been undertaken to know the impact of seasons on the occurrence of various stages (eggs, nymphs and adults) of broad mite, Polyphagotarsonemus latus at different fortnightly intervals on mulberry. Further, population of broad mite was correlated with weather parameters namely minimum temperature, maximum temperature, relative humidity and rainfall. The occurrence of broad mite persists throughout the year on mulberry with variation in their population. However, different stages of broad mite namely eggs, nymphs and adults were more during summer (March to June) followed by winter (November to February) and rainy (July to October) seasons. The weather parameters namely maximum temperature, minimum temperature, relative humidity and rainfall showed marginal positive relationship with the population of broad mite in different seasons. On the other hand, fecundity showed negligible negative correlation with maximum temperature, minimum temperature and relative humidity, while it was positive negligible correlation with rainfall. The nymphal stage showed slight negative correlation with all the weather parameters. However, adult population exhibited moderately negative relationship with maximum temperature and relative humidity, while it showed lower positive correlation with minimum temperature and rainfall.

Abstract
Jackfruit (Artocarpus heterophyllus), an economically valuable and nutritionally important fruit, contains various health-promoting ingredients that could supplement the nutritional needs of the world's rapidly growing population. Jackfruits are well-known for their varying fruit morphology, but little is known about their genetic and molecular basis. We identified 273,577 perfect SSRs using the jackfruit reference genome sequence. Out of 273,577 SSRs, 19,934 were genic, whereas 253,643 were non-genic. Annotation of the SSR-containing genes revealed that 10,445 and 9,489 SSRs were present in the annotated and non-annotated gene sequences. Out of 10,445 SSRs in annotated gene sequences, 683 were present in fruit-trait-related genes. The fruit-trait-related genic-SSRs identified in the present study may serve as functional markers for specific fruit-related traits.

Abstract
The freshwater bivalve molluscs, Indonaia caeruleus (75-78 mm shell length) were collected from banks of Kukadi River at Yedgaon during summer, monsoon and winter seasons for the study of histological changes in the digestive tubules. The histological study showed that, ducts and tubules of digestive gland grouped in the form of small lobules, separated by inter lobular connective tissues. The tubule consists of digestive cells and secretary cells. The primary tubules in the Indonaia caeruleus showed synchronized pattern of different phases such as fragmentation of spherules, holding phase and absorption phase, according to changes in water level over the animal bed, rainfall, oxygen contents and probable changes in the detritus matter (i.e. food availability) on the habitat. Tubule consists of two types of cells (a) digestive cells and (b) secretary cells. Amoebocytes are found scattered in the interlobular connective tissues. The diameter of primary digestive tubules was found maximum during monsoon while it was found minimum during summer and winter seasons. During monsoon tubules were in fragmentation spherules phase. The tubules progressed in holding and absorption phases from late monsoon to winter season. The absorption phase in the tubules was found dominant during winter which probably indicated less availability of food. The results of the study are discussed in the light of effect of environmental parameters over the habitat.

Abstract
The current study investigates insect visitor diversity and their roles in plant-pollinator interactions in the Murud area, aiming to enhance fertilization and agricultural productivity. Identifying 37 insect species across three orders and nine families, with Lepidoptera and Hymenoptera showing the highest diversity, underscores their vital role as pollinators. Additionally, 18 plant species, attracting a variety of pollinators like butterflies, bees, flies, beetles, hoverflies, and bumblebees, contribute to ecosystem biodiversity and support robust pollinator populations. The interplay between plants and insects, exemplified by species like Crinum asiaticum and Rosa indica, emphasizes the complexity of ecosystem dynamics and underscores the importance of maintaining diverse plant communities for sustaining healthy pollinator populations. Increased awareness among farmers about pollination mechanisms could lead to enhanced crop yields, strengthening the economy.
