This study aimed to optimize soybean cultivation in the Tarai region of Uttarakhand, India, by exploring the impact of different sowing dates on crop growth and yield using the Decision Support System for Agrotechnology Transfer (DSSAT) CROPGRO model. The experiment was conducted in 2022 and 2023 at Pantnagar, Uttarakhand, using a split-plot design with three replications. The model was calibrated and validated for different sowing dates, and key parameters such as emergence days, physiological maturity days, grain yield, harvest index, and leaf area index were compared between simulated and observed values. During validation RMSE and R2 was 48.44 and 0.90 for grain yield, 1.10 and 0.99 for physiological maturity, 0.042 and 0.99 for harvest index and 1.14 and 0.97 for LAI respectively. The results showed that adjusting sowing dates can significantly affect soybean growth and yield, with optimal sowing times resulting in higher yields and better crop performance. Specifically, sowing on July 22nd resulted in the highest grain yield, while sowing on August 21st led to the lowest. The DSSAT CROPGRO model proved to be a valuable tool for simulating soybean growth and predicting crop outcomes under varying environmental conditions.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":"23 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141336174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growth and development of plants, along with crop productivity, are substantially impacted by the adverse effects of global climate change. In view of this, a research initiative was undertaken to investigate the effects of distinct sowing dates and planting densities on the yield and economic aspects of groundnut in the hot arid region of Rajasthan, India. The experiment, conducted over a span of three years during the kharif seasons of 2017, 2018, and 2019 at Swami Keshwanand Rajasthan Agricultural University, Bikaner, Rajasthan, India. The experimental design utilized a split-plot layout with four replications, comprising nine treatments. The main plot treatments involved three different sowing dates (15th May, 30th May, and 15th June), while the sub-plot treatments encompassed three planting densities (1.67 lakh, 2.50 lakh, and 3.33 lakh plants per hectare). Notably, the diverse sowing dates and planting densities exhibited notable effects on groundnut yield and economic viability. Comparative analysis revealed that sowing on May 30th, while statistically comparable to June 15th sowing, yielded the highest number of branches, pegs, pods per plant, kernel and pod yield, net return, and benefit-cost ratio. Interestingly, the highest haulm yield per hectare was achieved with the May 15th sowing, yet the harvest index improved progressively as sowing was delayed from May 15th to June 15th. However, the various sowing dates had no discernible effect on kernels per pod, seed index, and shelling percentage. Furthermore, employing a planting density of 1.67 lakh plants per hectare was resulted in the highest counts of branches, pegs, pods, kernels per pod, seed index, and shelling percentage. Remarkably, the elevation in planting density up to 2.50 lakh plants per hectare led to enhanced kernel and pod yields, harvest index, and net return. In an intriguing interaction between sowing dates and plant populations, the most favorable pod yield, kernel yield, and net return were recorded with a planting density of 2.50 lakh plants per hectare for the May 30th sowing. These findings underscore the significant effect of sowing date and planting density on yield attributes and ultimately on groundnut yield in the challenging hot arid region. Therefore, the timing of sowing and the density of planting play pivotal roles in enhancing groundnut productivity within this region, particularly in light of the changing climate conditions.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":"51 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141342390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines the influence of optimized plant spacing and nutrient management on the performance of summer green gram. Proper spacing is crucial for minimizing competition for resources among plants, ensuring adequate sunlight, and promoting effective pest and disease control. Different plant densities and their impact on biomass production, pod formation, and seed quality are analysed. Nutrient management, particularly the balanced application of macro and micronutrients, plays a significant role in enhancing physiological and biochemical processes in the plant. The review highlights the importance of integrating organic and inorganic fertilizers to improve soil fertility, boost microbial activity, and increase nutrient uptake efficiency. Studies indicate that appropriate nitrogen, phosphorus, and potassium levels, along with essential micronutrients like zinc and boron, are vital for optimal plant development and yield. The synergistic effects of spacing and nutrient strategies on green gram's growth parameters, including plant height, leaf area index, nodulation, and chlorophyll content, are explored. This comprehensive review synthesizes current research findings and offers practical recommendations for farmers and agronomists aiming to enhance green gram productivity sustainably. By adopting optimal spacing and tailored nutrient management practices, significant improvements in yield and resource use efficiency can be achieved, contributing to food security and agricultural sustainability. The review underscores the need for continued research to refine these agronomic practices under diverse environmental conditions to fully realize the potential of summer green gram cultivation.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":"2 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141346640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes impact food security, crop yields, and the livelihoods of millions of farmers worldwide. Crops face threats from heat stress, changing pest and disease dynamics, water scarcity, and unpredictable growing seasons. Crop resilience involves a complex interplay of genetics, environmental factors, and agricultural practices. Researchers and agricultural scientists are exploring innovative approaches like selective breeding, genetic modification, and precision agriculture to enhance crop resilience. Integrating traditional knowledge and indigenous farming practices into modern agricultural strategies is essential for securing food production, ensuring the sustainability of agricultural systems, conserving biodiversity, and supporting community resilience in an uncertain climate future. Crop resilience is central to ensuring global food security, supporting rural livelihoods, preserving ecosystems, and advancing sustainable agriculture in the face of climate change challenges. Biochar, a climate-resilient agricultural amendment, is gaining attention for its role in enhancing agricultural sustainability and mitigating climate change. Its porous structure and high carbon content sequester carbon dioxide, improve soil health, and reduce nutrient leaching. Biochar's porous nature fosters a rich microbial community, aids in nutrient cycling, and aids in rehabilitating degraded soils. It also reduces synthetic fertilizer requirements and environmental pollution. Climate change significantly impacts crop agriculture, disrupting traditional growth patterns and threatening global food security. High temperatures cause heat stress, while droughts and floods cause soil desiccation, impairing crop yields. Increased plant diseases and pests spread, while higher CO2 levels stimulate photosynthesis but reduce essential nutrients. Rising temperatures disrupt vegetative and reproductive growth phases, pollination, and seed formation, compromising crop quality and market value. Biochar is a porous material formed through pyrolysis, a process where organic biomass is decomposed under limited oxygen conditions. It is primarily carbon-rich but contains hydrogen, oxygen, nitrogen, and minerals. As a soil amendment, biochar is a stable carbon sink with a high carbon content of 70-90%. Its porous structure allows it to efficiently adsorb and retain water, nutrients, and organic compounds. Its large surface area facilitates interactions with soil microbes and nutrient ions, and its high CEC helps in nutrient retention and soil fertility.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":"40 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141358774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, it is crucial to understand the mechanisms and processes underlying heat-related male sterility in order to maintain food security. Elevated temperatures elicit acclimation responses that permit pollen development under restricted heat stress conditions; physiological injury leading to pollen development and functioning failure occurs at higher temperature stress. Pollen and the surrounding anther tissues respond to increased temperature at the transcriptome, proteome, and metabolome levels. To counteract the damaging effect of misfolded proteins under heat stress, HSPs (Heat Shock Proteins) accumulate in the cytoplasm and organelles to stabilize, resolubilize, and refold proteins. The pathways leading to the production of carbohydrates, amino acids, phenolic compounds, polyamines, hormones and lipids are interconnected and contribute to the metabolic homeostasis required for the growth and viability of the pollen. The pathways leading to the production of carbohydrates, amino acids, phenolic compounds, polyamines, hormones and lipids are interconnected and contribute to the metabolic homeostasis required for growth and viability of the pollen. Using molecular markers to access specific genomic regions associated with a specific trait along with QTL (Quantitative Trait Loci) fine mapping can identify several candidate genes associated with thermo-tolerance.  A deep understanding of the molecular mechanisms and metabolic processes involved in the stress response to high temperatures in flowers and particularly in the male reproductive organs will be a major step towards developing of effective breeding strategies for high and stable production in crop plants.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":"18 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141360671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
