Green gram (Vigna radiata) and black gram (Vigna mungo) are prominent pulse crops crucial for global food security and agricultural sustainability. However, these pulse crops face substantial yield losses due to YMV.  Yellow Mosaic Disease (YMD), caused by the Mungbean yellow mosaic virus (MYMV), is a major biotic constraint affecting blackgram  and greengram production. Field screening for YMD resistance is often unreliable, as plants may escape infection even under high inoculation pressure, making it challenging to accurately identify resistant lines. In this case, artificial Screening of Yellow Mosaic Virus Causing   YMV Disease in Blackgram  and Green Gram during Kharif  Season was carried  out to screen the YMV diseases   in the glass house condition.  The study was performed under glass house condition by following Completely randomized design  with three replication. The aim of the study is to screen the entries for yellow mosaic virus disease under artificial condition. Among the forty-six entries tested, six entries—namely KUP 21-1, KUP 21-3, KUP 21-4, KUP 21-17, KUP 21-20, and KUP 21-21—were found to be highly resistant to MYMV. Additionally, one entry, KMP 21-1, was completely free from MYMV among the seventy-five entries screened. These resistant entries the potential to use these genotypes as donor sources for YMV resistance, facilitating indicate the development of high-yielding, MYMV-resistant varieties through backcross or marker-assisted backcross selection by introgressing resistance genes into agronomically superior but MYMVsusceptible genotypes.

The Nilgiri Tahr (Nilgiritragus hylocrius), an endangered mountain ungulate endemic to the Western Ghats of India, is a flagship species of the montane ecosystems, yet its habitat preferences and spatial ecology remain insufficiently explored. This study employed Species Distribution Modelling (SDM) using the Maximum Entropy (MaxEnt) algorithm integrated with Geographic Information System (GIS) to predict the potential distribution of Nilgiri Tahr in the Periyar Tiger Reserve (PTR), Kerala. Presence data were obtained from MSTrIPES field surveys (April 2024 to September 2025) and correlated with 24 environmental variables, including elevation, slope, aspect, NDVI, rainfall, temperature, land cover, and distance to water sources. Model performance was evaluated using the Area Under the Receiver Operating Characteristic Curve (training AUC = 0.923, test AUC = 0.922) and jackknife tests to determine the relative contribution of predictor variables. Habitat suitability was classified into three probability categories: Unsuitable, moderately Suitable and Highly Suitable. The model revealed that highly suitable habitats covered approximately 134.97 km², moderately suitable habitats spanned 249.52 km², and unsuitable areas accounted for 540.51 km². The most suitable habitats were concentrated along Ponnambalamedu, Mangaladevi, Palkachimala, Medhakanam, Pachamudi, Kumarikulam, Vaikolpadappu, and Manamuttymala, extending towards Circle Road, Uppupara, Zero Point, Venkalapara, Ottamaram, and Churulipara. These zones are characterized by steep grassland-Shola mosaics and rugged high elevation cliffs, providing ideal foraging, resting, and breeding environments for the species. Conservation management should emphasize the maintenance of high-altitude grassland connectivity, protection of Shola grassland ecotones, and integration of Nilgiri Tahr habitats into PTR’s conservation and monitoring framework to ensure long-term population persistence under changing climatic conditions.

The field experiment was conducted to study the comparative performance of various insecticides and biopesticides against Helicoverpa armigera and Spodoptera frugiperda. Chlorantraniliprole 18.5SC @ 0.4ml/l showed the most effective control on H. armigera and S. frugiperda, with pooled mean larval population of 0.42 and 1.16 larvae/plant followed by emamectin benzoate 5 SG @ 0.4g/l (0.52 and 1.24 larvae/plant), spinaosad 45 SC @0.3 ml/l (0.62 and 1.32 larvae/plant), indoxacarb 14.5 SC@ 1ml/l (0.73 and 1.42 larvae/plant) and novaluron 10 EC @0.1ml/l (0.83 and 1.52 larvae/plant). The least effective treatment was agniastra @1000ml / 50 l (1.19 and 1.81 larvae/plant) after control (2.08 and 2.82 larvae/plant) followed by nimbicidine 0.03 EC @5ml/l (1.03 and 1.75 larvae/plant) and Bacillus thuringenesis @ 2g/l (0.92 and 1.62 larvae/plant).  The results concluded that chlorantraniliprole, emamectin benzoate, indoxacarb and novaluron consistently demonstrated a significant reduction in larval population and the longest residual. Whereas, Bt and nimbicidine provided moderate control and the shortest residual capacity, which is favorable to the environment.

Field Experiments were conducted at Agronomy Research farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (Uttar Pradesh, India), during Kharif season of 2024 and 2025.The study was carried in a split plot design with 3 replications. In main plot 3 rice establishment methods and in sub plot 5 weed management practices were included. The results revealed that transplanting methods of sowing registered the highest nitrogen, phosphorous and potassium uptake by rice crop and lowest nutrient removal through weeds. Among weed management practices, maximum uptake by rice with respect to nitrogen, phosphorous and potassium and minimum removal by weed regarding N, P and K was recorded in treatment hand weeding at 15, 30, 45 and 60 DAS/DAT which was observed statistically at par with pre application of pendimethalin @ 1000 g a.i. ha-1 f/b brown manuring by bispyribac sodium @ 25 g a.i. ha-1 at 25 DAS/DAT. Among different weed management practices, combined application of pendimethalin @ 1000 g a.i. ha-1 f/b brown manuring by bispyribac sodium @ 25 g a.i. ha-1 or hand weeding 15, 30, 45 and 60 DAS/DAT was found effective in controlling weeds and increase in the quality and quantity of rice. Among the establishment method transplanting was found effective in increase in the yield, nutrient content of the crop and substantially reduction of nutrients removed by weed in rice field.

The present study investigated the utilization of banana peel waste for the sustainable production of fortified yogurt. Banana peel powder was incorpo­rated into yogurt at three different levels T1 (5 g), T2 (8 g), and T3 (10 g) along with a control T0, and evaluated for sensory characteristics and proximate composition. Sensory evaluation was conducted by a panel of ten semi-trained members using a 9-point hedonic scale. All sensory parameters taste, texture, appearance, flavor, color, and overall acceptability showed statistically significant differences (F = S at 5% level of significance) among treatments. T2 emerged as the most acceptable formulation with an overall acceptability score of 8.4, followed by T1 (7.9) and T3 (7.7). Proximate analysis revealed that the enriched yogurt contained moisture (72.21 ± 0.24%), ash (1.53 ± 0.05%), protein (5.06 ± 0.08 g), dietary fiber (1.33 ± 0.11 g), fat (4.87 ± 0.05 g), carbohydrate (14.9 ± 0.40 g), and energy (125 ± 1 kcal per 100 g), reflecting a nutritionally superior profile over conventional plain yogurt. The findings confirm that banana peel typically discarded as agro-industrial waste can be effectively valorized as a functional in­gredient in yogurt fortification, supporting the goals of sustainable food production, waste reduction, and development of health-promoting dairy products.

In the summer of 2023, twenty-two pumpkin gen­otypes were evaluated for nineteen qualitative and morphological characters. Statistically significant differences were recorded for all traits studied, pointing to the presence of rich genetic variability. In most cases, the phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV), reflecting environmental influence along with genetic control. The highest PCV and GCV values were obtained for number of fruits per vine, vine length, average fruit weight and vitamin-C. These traits also expressed high heritability coupled with genetic advance, suggesting their reliability for effective selection. Correlation studies indicated that fruit yield was positively and significantly related to average fruit weight and number of fruits per vine. Results of path analysis further confirmed the direct significant influence of vine length, fruit weight and fruit number on yield. Based on cluster analysis, the genotypes were grouped into three distinct clusters, Cluster I having twelve accessions, Cluster II nine, while Cluster III was represented by a single geno­type. The largest intra-cluster distance was in Cluster II, whereas the maximum inter-cluster distance was observed between Clusters II and III. Cultivar VNR 14 among the assembled genotypes stood out for its early flowering and fruit set, higher fruit yield and superior TSS. This genotype can be utilized as a prom­ising parent in future breeding programs to exploit heterotic potential and develop improved cultivars.

As dragon fruit is one of the ornamental fruits and it is of immense important now a days because of highly nutritious and medicinal values. Dragon fruit are sensitive to disease infection but the crop has gained less attention in disease management practices which causes high yield reduction. So, knowledge on the causal organisms associated with the diseases of dragon fruit is the foremost priority to develop dis­ease management practices. This research study aims to investigated the characteristics of fungal wilt disease of dragon fruit in three major dragon fruit growing districts of Nagaland, India. A systematic survey was conducted in Chumoukedima, Niuland and Dimapur districts for the symptomatologic study and disease sample collections. The wilt dis­-ease symptoms were characterised by yellowing of stems, stem rot, vascular discolouration, wilting and shrivelling and death of the plant. Fungal pathogens were isolated from the disease samples and pathoge­nicity studies confirmed the causal agent of the wilt disease of dragon fruit plants. The isolate was iden­tified as Rigidoporous vinctus through morphological studies and molecular characterization. This study provides an information on the causal organism of wilt disease of dragon fruit which helps in developing effective disease management strategies and future research on the causal pathogen.

Mustard  &  Rapeseed are among India’s most important rabi oilseed crops, contributing substantially to domestic edible oil supply.  This study analyzes long-term trends and forecasts area, production and yield of mustard and rapeseed in India using time-series data from 1950-51 to 2021-22. Compound growth rate, the Cuddy–Della Valle instability index and additive decomposition analysis were used to assess growth patterns and sources of change in production, while linear, logarithmic, quadratic and cubic trend models were compared using R², RMSE and MAPE to identify the best-fitting model for forecasting.  The results show that compound growth rate was found highest for production (3.82% per year), followed by yield (2.09% per year) and area (1.69% per year), while decomposition analysis revealed that yield effect (59.45%) was the major contributor to the growth in production.  On the basis of the cubic model,  area is likely to decline from 6.41 to 5.74 million hectares, while production and yield are likely to increase from  9.75 to 11.43  million  tonnes and from 1457.77 to 1673.62 kg/ha, respectively, during 2023-2032. These  findings  indicate that future growth in mustard and rapeseed production in India will depend largely on continued yield improvement through better varieties and farm management, rather than area expansion.

Floodplain wetlands play an important role in hydrological regulation, biodiversity conservation and livelihood support in monsoon-dominated river basins. They are also increasingly recognized as critical Nature-based Solutions (NbS) that contribute to climate adaptation, flood moderation, groundwater recharge, carbon sequestration and livelihood resilience, particularly for vulnerable rural communities in climate-sensitive landscapes. However, increasing climate variability and anthropogenic disturbances are adversely affecting the ecological functions and ecosystem services provided by these wetlands. The present study evaluates the hydrological, ecological and livelihood impacts of a community-driven wetland rejuvenation intervention implemented at the Mirhiriya wetland in the Rapti River basin of Gorakhpur, eastern Uttar Pradesh, India. Major restoration activities included selective de-siltation, restoration of hydrological connectivity, removal of invasive aquatic vegetation and conservation of a vegetated Natural Filtration System (NFS). Pre- and post-intervention assessments conducted during January 2024 and January 2026 indicated substantial improvement in wetland functioning following restoration. Water depth in the central wetland increased by 54.55%, while the spatial extent of waterlogging decreased by 48.62%. Water quality improved considerably, and aquatic macrophyte richness increased from 4 to 10 species, while fish species richness increased from 4 to 8 species following rejuvenation. Wetland rejuvenation also enhanced livelihood opportunities through improved fisheries and wetland resource utilization among local communities. The findings demonstrate that community-driven wetland rejuvenation can function as an effective nature-based solution for improving ecological resilience and livelihood security in flood-prone agricultural landscapes.

The plant species which are grown in close surroundings of Thermal power plants are worst affected by the higher emission rate of air borne fly ash & gradually becomes static Eco-sinks for harmful thermal emissions. So, the present study used Air pollution tolerance Index (APTI) to assess the response of commonly grown fruit tree Psidium guajava L. towards fly ash emissions in Rattanpur village situated in close vicinity of thermal power plant in Yamuna Nagar city. Leaf samples of selected plant individuals of fly ash affected area and control area were analyzed for the assessment of foliage dust load, macro-morphological leaf traits and biochemical attributes, including Leaf extract pH, Relative water content (RWC), chlorophyll content and Ascorbic acid content. The APTI results of the selected plant species were found to be in sensitive category due to the declined level of ascorbic acid and chlorophyll content with respect to fly ash emission. However, results indicates that P. guajava  L. can be considered as bioindicator plant in affected area but should not be solely recommended for the development of “Green belt” in fly ash affected village.

Land-use change is a major driver of soil degradation in tropical ecosystems, influencing soil organic carbon (SOC), nutrients and ecosystem productivity. This study evaluated the effects of five contrasting land-use systems, namely natural forest (NF), degraded forest (DF), fallow land (FL), pine plantation (PP), and paddy field (PF), on soil physico chemical properties in Manipur, Northeast India. Soil samples were collected from all land use types to a depth of 1 m and divided into four layers (0–15, 15–30, 30–60, and 60–100 cm).  Soil samples were analyszd for soil bulk density, moisture content, texture, texture, pH, SOC, available nitrogen (Navail), phosphorus (Pavail), and exchangeable potassium (K+), calcium (Ca), and magnesium (Mg).  Two-way ANOVA revealed significant effects of land-use type, soil depth, and their interaction on most soil properties (p < 0.001). Natural forest soils maintained the highest SOC, Navail, and moisture content. Fallow land exhibited soil properties comparable to those of NF, indicating substantial recovery of soil fertility during secondary succession. In contrast, pine plantation soils showed the lowest SOC and available P, associated with acidic conditions and slow decomposition of conifer litter. Paddy fields were characterised by higher pH, K+, Ca, and Mg due to prolonged flooding and management practices. Soil nutrient concentrations and moisture content declined significantly with increasing depth, whereas bulk density increased. Principal Component Analysis explained 73.28% of the total variance and clearly distinguished land-use systems based on their soil properties. The findings demonstrate that land-use conversion substantially alters soil physicochemical properties and highlight the importance of maintaining natural forests and promoting fallow-based restoration strategies to sustain soil fertility and ecosystem functioning in tropical landscapes.

This study focuses on the development and evaluation of a climate-resilient finger millet-based premix as a nutritionally rich and functionally efficient food product. The research was conducted in the Department of Food and Nutrition, College of Community Science, Acharya Narendra Deva University of Agriculture and Technology (ANDUAT), Kumarganj, Ayodhya, Uttar Pradesh. The premix was formulated using roasted finger millet (Eleusine coracana) flour blended with roasted gram flour in different proportions (70:30, 80:20, 90:10 and 100:0), represented as T1, T2, T3, and T4, with wheat flour-based formulation serving as control (T0). Among all formulations, T3 (90:10) showed the most desirable physicochemical, nutritional, and sensory characteristics. This optimized sample recorded moisture content of 10.5%, water absorption capacity of 135 g/100 g, bulk density of 0.69 g/ml, swelling capacity of 150%, and pH of 6.40, indicating good functional and processing properties. Nutritional analysis revealed an energy value of 340 kcal/100 g, with 73 g carbohydrates, 11.5 g dietary fiber, 12.5 g protein, 1.4 g fat, 340 mg calcium, and 4.9 mg iron. Sensory evaluation using a 9-point hedonic scale indicated high consumer acceptability, with an overall acceptability score of 8.75, categorized as “like very much.” The study confirms that incorporation of finger millet and roasted gram flour significantly enhances nutritional and functional quality without compromising sensory attributes. Furthermore, the use of finger millet, a climate-resilient and low-input crop, highlights its potential in promoting sustainable agriculture, resource conservation, and ecological stability. Overall, the developed premix represents a nutrient-dense, consumer-acceptable, and environmentally sustainable food product with strong potential to improve dietary quality and support food and nutritional security.

Hornbills (Family: Bucerotidae) are ecologically important frugivorous birds that contribute significantly to long-distance seed dispersal, forest regeneration, and the maintenance of tropical forest ecosystems. Despite their ecological significance, baseline information on the distribution and diversity of hornbill species in the protected areas of the Terai region of Uttar Pradesh remains limited. The present study assessed the distribution, abundance, and species diversity of Indian Grey Hornbill (Ocyceros birostris) and Oriental Pied Hornbill (Anthracoceros albirostris) across four protected areas of the Terai region, namely Pilibhit Tiger Reserve, Katarniaghat Wildlife Sanctuary, Sohagi Barwa Wildlife Sanctuary, and Bakhira Bird Sanctuary. Field surveys were conducted using random surveys and point count methods. Species diversity was evaluated using Simpson’s Index (D), Simpson’s Diversity Index (1−D), Simpson’s Reciprocal Index (1/D), Shannon–Wiener Diversity Index (H′), and Shannon Equitability Index (EH). The Indian Grey Hornbill was recorded from all four protected areas and exhibited greater overall abundance than the Oriental Pied Hornbill, which was absent from Bakhira Bird Sanctuary during the study period. Among the surveyed protected areas, Katarniaghat Wildlife Sanctuary recorded the highest species diversity (Shannon–Wiener Diversity Index, H′ = 0.67) and species evenness (EH = 0.96), whereas Bakhira Bird Sanctuary exhibited the lowest diversity because only one hornbill species was recorded. Comparative analyses demonstrated clear variation in hornbill diversity and community composition among the protected areas. The observed differences in species occurrence and diversity indicate that hornbill assemblages vary across protected landscapes of the Terai region and suggest that habitat characteristics influence community composition. The study provides baseline ecological information on the distribution and diversity of hornbill species in the protected areas of Uttar Pradesh and establishes a scientific foundation for future ecological monitoring, habitat assessment, and conservation planning within the Terai landscape.

The present study assesses the spatial pattern of lichen diversity around Bongaigaon Refinery. Sampling was conducted from 20 sites located in four directions at distances of 2, 4, 6, 8 and 10 km from the refinery. A total of 84 lichen species belonging to 30 genera and 17 families were recorded. Graphidaceae was the most abundant family, while crustose lichens represented the major growth form (76%), followed by foliose (22%) and leprose forms (2%). Species richness increased with distance from the refinery, from 21 species at 2 km to 64 species at 10 km. The chi-square analysis showed significant variation in species richness among distances (χ² = 30.25, df = 4, p<0.01). Sørensen similarity value was highest between the 8 km and 10 km sites (0.75), suggesting greater species similarity and stability at farther distances from the pollution source. Pyxine cocoes showed the highest frequency (100%), whereas Chrysothrix chlorina, Cryptothecia striata and Dirinaria consimilis were also widely distributed (95%). The study provides baseline information on lichen diversity around a point source and supports its use for future biomonitoring around refinery areas.

At the present work Potassium 5-Chlorosalicylhydroxamate and its complexes  Fe (II), Co (II) and Cu (II) were studied. Firstly 5-chlorosalicylhydroxamic acid had been prepared by the reaction of 5-chlorosalicylate and free hydoxyamine and was characterized by its melting point (>200℃), FT IR showed characteristic spectral band at  3324 cm–1 due to (N-O) stretching frequency and at 1626 cm–1 due to (C=O) stretching frequency. The Proton NMR showed spectrum show singlets at around 11.60 δ ppm and 12.40 δ ppm, which may be assigned to ‒NH and phenolic ‒OH of salicylhydroxamate group which show the linkage of  5-chlorosalicylhydroxamate group through  oxygen atoms of carbonyl  and  hydroxylamine group. The data from spectral studies suggested that the ligand act as a neutral bidentate ligand  [O, O] ligand involving the hydroxamate (‒NHO) and carbonyl oxygens, giving rise to penta-coordinated metal complexes in [M(HL)Cl2]K and hexa-coordinated in [M(HL)2Cl2]K. The antibacterial and anti-fungal of compounds was tested against bacterial strains- Pseudomonas aeruginosa and Bacillus subtilis using agar well diffusion method and  fungal strains- Sclerotinia sclerotiorum, Trichoderma harzianum. Cycloheximide were used as the standard antifungal agents whereas Chloramphenicol was used in the technique as the standard antibacterial agent. Compound (1d);  [Co(HL)2Cl2]K showed good antibacterial activity i.e 33 mm and 24 mm against P. aeruginosa  and B. subtilis and  good antifungal activity i.e. 28 mm against S. sclerotonia and T. harzianum.

Variety of the living organisms, biological systems and biological processes found on Earth constitute the Biodiversity. India accommodates good amount of world’s biodiversity making it one of the 17 mega diversity countries in the world. Conservation of biodiversity is of utmost priority now-a-days. Rollapadu Wildlife Sanctuary, Nandyal district (formerly in Kurnool district), Andhra Pradesh is one of the recognised conservation area for Great Indian Bustard. Though research activities and surveys were made in this area regarding the conservation of the Great Indian Bustard, very little is unveiled so far on the associated avian species. Various avian fauna having adapted to different habitats inhabit the sanctuary for certain period in a year. Balance of biodiversity is very well observed especially in relation to avian fauna, which draws more attention on the conservation efforts of Great Indian Bustard, by the Ministry of MoEFCC, Government of India at State and Central levels.

Tamarind is a highly cross-pollinated crop and hence, wide variability is common in this species as it is propagated through seeds. Such seedlings exhibit a wide range of variations, which aids in the selection of the superior desirable genotypes. It offers more avenues for establishing desirable clones by simple seedling selection. Plus, trees or the elite trees selected for total yield, fruit size and quality of fruit, are the starting point of any tree improvement program. Selection of a large number of elite trees serves as an immediate seed source with fairly high genetic gain. In nature, lot of variations in respect of fruit shape and size, fruit and pulp color, TSS, acidity and earliness in bearing of this fruit are evident. Advantage of these variations can be taken to evolve a selection of superior seedling. The investigation aimed to assess the morphological, physical, and biochemical variability among twenty Garo Hills Tamarind (GHT) genotypes collected from different locations in the Garo Hills region of Meghalaya. The findings revealed a wide range of variation among the collections. Cluster analysis identified Cluster V (GHT5, GHT11, and GHT13) as the elite group based on overall performance. Among them, GHT11, collected from Rangmangre (North Garo Hills), emerged as the most promising genotype, combining high-quality biochemical traits with superior fruit physical characteristics. The findings provide valuable insights for tamarind improvement programs and highlight the genetic potential of local germplasm for commercial cultivation.

Climate-Smart Agriculture has emerged as an important approach to address the growing challenges posed by climate change, resource limitations and climate-related stresses in agricultural production. Barley (Hordeum vulgare L.) is an important Rabi cereal crop used for food, feed, malt and various industrial purposes. Its ability to perform well under drought, salinity, marginal soils and low-input conditions makes it a promising crop for climate-resilient agriculture. In India, barley production is mainly concentrated in Rajasthan, Uttar Pradesh, Haryana, Madhya Pradesh and other northern and central regions, although considerable differences in area, production and productivity exist among states. This assessment assesses climate-smart technologies for barley seed production under Indian conditions, with emphasis on varietal selection, quality seed sources, seed treatment, land preparation, timely sowing, nutrient and irrigation management, weed and pest management, field inspection, rouging, isolation, harvesting, seed processing, storage and certification. Practices such as efficient water management, laser land levelling, balanced nutrient application, integrated pest and disease management, conservation-oriented tillage and energy-efficient technologies can improve resource-use efficiency and production stability. Regular field inspection and timely rouging are important for maintaining genetic purity, while proper seed processing and storage help preserve seed viability and quality. The review also highlights key grain and seed quality traits, including kernel appearance and color, hull characteristics, uniformity, nutritional composition and suitability for food and malting purposes. Overall, combining quality seed production with climate-smart agronomic and resource-management practices can improve barley productivity, seed quality, genetic purity, resilience and sustainability, while supporting long-term food and nutritional security under changing climatic conditions.

Stored-product insect pests are a major cause of post-harvest losses globally and in Sri Lanka, where favorable climatic conditions and suboptimal storage practices exacerbate infestations. This study assessed the knowledge, attitudes, and practices (KAP) of household grain consumers and grain sellers (Retail stores, supermarkets and warehouses) regarding stored-grain pests and their management across four districts in Sri Lanka (Ampara, Kandy, Gampaha and Colombo). A structured questionnaire survey was conducted among 400 consumers and 120 sellers using purposive sampling, followed by KAP-based analysis. Results indicated that overall knowledge levels among both consumers and sellers were low, with 63% and 77% respectively categorized as having poor knowledge. However, 67% of the consumers reported good storage practices, particularly the use of plastic containers and regular cleaning. Poor storage practices by sellers (96% poor practices), such as use of synthetic and gunny bags, often placed on floors, increased vulnerability to pest infestations. Attitudes towards pest control especially use of plant-based pest control methods were largely negative (82% consumers and 80% sellers. Chemical control methods were rarely used at household level but occasionally applied in warehouses, such as Actellic 50EC (pirimiphos-methyl) raising safety concerns. The findings for the first time revealed significant gaps in awareness and pest management practices, particularly at the commercial storage level in Sri Lanka. The study highlights the need for targeted awareness programs, improved storage practices, and integration of indigenous and environmentally friendly pest control strategies to enhance food security and reduce grain losses in Sri Lanka.

The study investigates the spatial distribution and extent of open space dumping sites (OSDS) in Lakshmangarh Municipality (Sikar district, Rajasthan), where residents routinely throw household trash in open fields. A total 161 open dumping sites (ODS) were identified in the 40 municipal wards through a geospatial inventory and field-based survey. The results show that there is a significant geographic variation in the level of open dumping and classified in four categories (high, moderate, low and no open dumping). The ward no 9, 28 and 39 are identified as high-dumping wards, which together accounting for 56 dumping sites (34.78%). The 10 wards identified under the moderate category which consist of 64 sites (39.75%), while 20 wards classified as low-dumping wards with 41 sites (25.47%). The high rate of open dumping, especially in vacant spaces, suggests a lack of waste collection, waste disposal facilities and public waste management. These unsupervised disposal methods can lead to land degradation, soil and groundwater contamination, undesirable environmental conditions, and a higher risk for environmental and public health. The study emphasizes the importance of establishing an effective and sustainable MSW management system by optimizing waste collection and transport, source separation, recycling and resource recovery, scientific disposal of waste, periodic tracking of hot spots of waste disposal, and increasing awareness and involvement of the public in the process. The results serve as a spatial basis for prioritizing interventions in waste management and in improving environmental quality and public health in the study area.

A pot culture experiment was conducted with wheat genotypes during the Rabi season of 2023–24 at Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya. The temperature was maintained around 38 to 40oC in polyhouse condition so that reproductive stage of wheat genotypes could face heat stress environment. The wheat genotypes were evaluated for membrane stability index (MSI), chlorophyll stability index (CSI), catalase activity, test weight and grain yield performance under heat stress. The cell membrane stability highly affected due to electrolytes leakage under heat stress. The test weigh and grain yield was less affected in high MSI genotypes. The chlorophyll stability genotypes stay green during terminal heat stress and maintained the metabolic acitivity during grain filling stage. High catalase activity genotypes prevent the lipid peroxidation and prevent plant from oxidative damage. Genotype NWL-102 had high MSI, CSI, high catalase activity and less reduction yield over NWL 101, NWL 103 and NWL 104. The heat stress significantly reduced test weight and grain yield under heat stress regimes. The tolerant wheat genotypes less affected as compare to susceptible ones.  The high MSI, CSI, catalase activity and grain yield stability under heat stress environment may be use it as donor for further improvement of wheat genotypes for heat tolerant traits.
