The field experiment was carried out during two successive Rabi seasons of 2021-22 and 2022-23 at the Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.).The treatment combinations of 4 crop residue management, viz. conventional tillage without residue, conventional tillage with residue (3 t/ha rice residue), zero tillage without residue, zero tillage with residue (3 t/ha rice residue) and 5 weed management practices, viz. Triallate 50% EC @ 1250 g a.i. ha-1, Triallate 50% EC @ 2500 g a.i. ha-1, Clodinafop propargyl 15% + Metsulfuron methyl 1% (60 g + 4 g a.i. ha-1), hand weeding at 20 and 40 days after sowing (DAS) and weedy check in wheat were tested with 3 replications in split-plot design, keeping crop residue management in main plots and weed management practices in subplots. Among the different crop residue management, zero tillage with residue was found most effective in maximizing nutrient content and nutrient uptake followed by conventional tillage with residue. Conventional tillage without residue showed lowest values of on nutrient content and uptake by crop. While in case of weed management practices hand weeding at 20 and 40 days after sowing (DAS) had a significant impact on maximizing nutrient content and nutrient uptake followed by post-emergence application of Clodinafop propargyl 15% + Metsulfuron methyl 1% (60 g + 4 g a.i. ha-1).

Aims: The aim of this study was to evaluate the genetic variation, heritability, and direct and indirect effects of various traits on grain yield in 64 rice genotypes under early transplanted conditions. Study Design: The study utilized a randomized block design with two replications. Place and Duration of Study: The research was conducted at the Agriculture Research Station, Sakoli, District. Bhandara under Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra, India during the Kharif season of 2022. Methodology: The experimental material comprised 64 rice genotypes along with the regional check Sakoli-6. Observations were recorded on the following traits: days to 50% flowering, days to maturity, plant height (cm), number of panicles per square meter (panicles/m²), and grain yield (kg/ha). Data were analyzed for genetic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), heritability, genetic advance, correlation, and path analysis to determine the direct and indirect effects of these traits on grain yield in early transplanted condition. Results: High GCV and PCV were observed for grain yield, with moderate values for the number of panicles/m², indicating significant variability conducive to improvement. Grain yield, number of panicles/m², and plant height exhibited high heritability and genetic advance. Whereas, correlation analysis showed significant positive correlations between the number of panicles/m² and grain yield, and significant negative correlations between days to 50% flowering and days to maturity with grain yield. Path analysis indicated that days to 50% flowering, followed by the number of panicles/m² and plant height, had the highest positive direct effects on grain yield. Conclusion: The study identified the number of panicles/m² as a critical trait for selecting superior genotypes. Based on these findings, the rice genotypes RP 6496-JB 202-4-6-1-1-1-1, OR 2800-4, and KNM 13557 were recommended for further breeding programs under early transplanted conditions.

This comprehensive review focused on understanding the critical interplay between Brassinosteroids (BRs), a class of plant hormones, and the high-temperature stress response in wheat (Triticum aestivum) in the context of climate change. In 2022-23, heat stress caused by a spike in temperatures in mid-March 2022 reduced India's wheat crop yields by 10-15%. This lowered the country's forecasted wheat production from 110 million metric tons (MMT) to 99 MMT for the 2022/23 market year (April-March) (USDA, 2023). The adverse effects of climate change and abiotic stresses on agriculture and crop productivity are well-established, with rising temperatures identified as a significant factor in the decline of plant growth and yield. In light of this, this review aims to delve into the intricate relationship between BRs and wheat's response to high-temperature stress. Given that global mean surface temperatures have already increased and are projected to continue rising throughout the 21st century, it is imperative to explore innovative strategies to mitigate the detrimental impacts on crop productivity. To this end, the study seeks to enhance our understanding of how BRs influence the growth and yield of wheat when exposed to high-temperature stress conditions. The overarching goal is to develop effective strategies that can bolster the resilience and productivity of wheat, which is a cornerstone staple crop worldwide, facing the escalating challenge of climate change. This review builds on the existing body of knowledge, synthesizing current research findings and shedding light on the potential of BRs as a key player in ameliorating the consequences of climate change in agriculture.

A field experiment was conducted at the Instructional-cum-Research (ICR) Farm, Assam Agricultural University, Jorhat. The experiment was laid out in split-plot design with three replications. The treatments consisted of five levels of irrigation in main plot viz., I0:Rainfed, I1: Irrigation at critical growth stages, I2: Irrigation at IW:CPE ratio of 1.0, I3: Irrigation at IW:CPE ratio of 1.2 and I4: Irrigation at IW:CPE ratio of 1.4 along with four levels of N- N0: 0 kg N/ha, N1: 30 kg N/ha, N2: 60 kg N/ha and N3: 90 kg N/ha in sub- plots. The soil of the experimental site was sandy loam in texture, medium in organic carbon, available N and available P2O5, acidic in reaction and low in available K2O. The result revealed that the highest leaf area index (LAI) recorded in irrigation at IW:CPE ratio of 1.4 at all the three cuts respectively during both the years. The crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) of ryegrass as influenced by different irrigation regimes were found to be non-significant at 30 DAS while at later growth stages i.e. 45 DAS, 60 DAS, 90 DAS and 120 DAS were significantly influenced during both the years. The application of irrigation at IW:CPE of 1.4 produced higher value of CGR, RGR but the highest NAR was recorded in rainfed treatment. The data on LAI as influenced by different N levels was found to be significant in all three cuts. Application of 90 kg N/ha recorded the highest LAI. The CGR, RGR and NAR as influenced by different N levels were found to non significant at 30 DAS but significantly influenced at later growth stage i.e. 45 DAS, 60 DAS, 90 DAS and 120 DAS during both the years. The highest data on CGR and RGR were recorded in 90 kg N/ha but the highest NAR was found in 0 kg N/ha.
在乔哈特阿萨姆农业大学的教学科研（ICR）农场进行了一项田间试验。试验采用分小区设计，三次重复。主小区的处理包括五个灌溉水平，即I0：雨水灌溉；I1：关键生长期灌溉；I2：IW:CPE 比值为 1.0 时灌溉；I3：IW:CPE 比值为 1.2 时灌溉；I4：IW:CPE 比值为 1.4 时灌溉；子地块中的四种氮含量--N0：0 千克氮/公顷；N1：30 千克氮/公顷；N2：60 千克氮/公顷；N3：90 千克氮/公顷。试验地的土壤质地为沙壤土，有机碳、可利用氮和可利用 P2O5 含量中等，反应呈酸性，可利用 K2O 含量低。结果表明，在灌溉条件下，IW:CPE 比值为 1.4 时，两年中所有三茬作物的叶面积指数（LAI）最高。不同灌溉制度对黑麦草的作物生长率（CGR）、相对生长率（RGR）和净同化率（NAR）的影响在 30 DAS 时不显著，而在生长后期，即 45 DAS、60 DAS、90 DAS 和 120 DAS 时则有显著影响。灌溉的 IW:CPE 值为 1.4 时，CGR 和 RGR 值较高，但雨水灌溉处理的 NAR 值最高。不同氮水平对 LAI 的影响数据在所有三季中都很显著。施用 90 千克氮/公顷的 LAI 最高。不同氮肥水平对 CGR、RGR 和 NAR 的影响在 30 DAS 时不显著，但在生长后期，即这两年的 45DAS、60DAS、90DAS 和 120 DAS 有显著影响。90 千克氮/公顷时的 CGR 和 RGR 数据最高，但 0 千克氮/公顷时的 NAR 最高。

Groundnut is cultivated mainly by small and marginal farmers. Seed cost and sowing are stated to be the most expensive operations which combined are responsible for about 45% of the entire cost of groundnut cultivation. The seed cost is increased mainly by the operation of shelling, which raises it to 3 times. The objective of this research was to test the viability of sowing groundnut with pods after proper seed treatment to reduce the shelling cost. Treatments include four spacing and three nutrient levels. It was sown in the spacing of 30 cm × 10 cm, 20 cm × 20 cm, 25 cm × 15 cm, and 30 cm × 15 cm. The different nutrient levels followed were the soil-based recommendation approach, 100% Recommended dose of fertilizers (25: 50: 75 N, P2O5, K2O kg ha-1) and, 125% Recommended dose of fertilizers (31.25: 62.5: 93.75 N, P2O5, K2O kg ha-1). Groundnut response was evaluated based on dry matter production, number of pods per plant, hundred pod weight, pod yield, haulm yield, harvest index and B: C ratio. The combination of 30 cm × 15 cm spacing, and 125% recommended dose of fertilizers (S4N3) documented the highest double pods per plant, hundred pod weight, highest pod yield of 3791 kg ha-1 and benefit-cost ratio of 2.89. The higher yield as well as the higher benefit-cost ratio, indicates the practical feasibility and economic viability of adoption of pod-seeded groundnut.

The research was conducted to determine the effect of the application of PNSB on the growth and yield of komak beans under shade. The experiment was arranged in a Split Plot Design, consisting of two factors, namely shade as the Main Plot and concentration of PNSB as Sub-Plots. The shade consists of two levels (no shade and 50% shade). The PNSB concentration consists of three levels (0; 5; and 10 mL L-1). Each treatment was carried out with four replications. Data were analyzed using analysis of variance and continued with Duncan's Multiple Range Test at a 5% significance level. The results showed that the effect of shade was significantly different on stem diameter at 70 DAP, chlorophyll content (a, b, and total), and the number of dry seeds, very significantly different to stem diameter at 105 DAP, dry pod weight, number of dry pods, dry seed weight, and light intensity. 50% shade reduces the yield component even if PNSB is provided. The effect of PNSB was not significantly different on all variables, except for the number of leaves at 35 DAP and total N content. Application of PNSB 10 mL L-1 increased the number of leaves aged 35 DAP and the total N content, both without shade and with shade, increased total chlorophyll content with 50% shade, but decreased without shade.

The present investigation was carried out to identify soil fertility constraints and map the fertility status of erstwhile Warangal District, Telangana, India using geographic information system (GIS) and global positioning system (GPS). 241 geo-referenced surface soil samples (0-20 cm) from the study area were analyzed for their fertility parameters. Soil fertility maps were prepared for each parameter under GIS environment using Arc-GIS v 10.8.2. The soils in study area were slightly acidic to slightly alkaline in reaction (6.16 - 8.34), non saline in nature (0.14 to 1.00 dS m–1) and low to high (0.12 - 1.14%) in organic carbon (OC%) content. The soils were low in available nitrogen (136 to231 kg ha-1), low to high in available phosphorus (14.00 to 166.00 kg P2O5 ha-1) and medium to high in available potassium (199 to 997 kg K2O ha-1). The wide variation from deficient to sufficient was observed in the status of available zinc (0.13 to 2.05 mg kg-1), iron (0.09 to 11.80 mg kg-1), copper (0.14 to 2.14 mg kg-1) and manganese (0.18 to 10.30 mg kg-1). The soil fertility status in study area revealed that soil organic carbon, available nitrogen and zinc are important soil fertility constraints in the erstwhile Warangal District Telangana India. To build up organic matter, zinc content, native nitrogen and maintain nutrient balance in the soil the farmers are advised to adopt farmyard manure (FYM) and ZnSO4 application regularly.
