International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad in terminal period can be controlled and manage without investing on high-cost irrigation inputs but simply by utilising the residual moisture timely couple with other short or mid duration kharif rice varieties which may give farmer ample time for this demonstration. T4a-31P-1317 Growth and Growth Parameters of Soybean influenced by different Land Configurations and Crop Residue Management Practices S. S. Kinge 1* , G. A. Bhalerao 2 , A. J. Rathod 1 , M. N. Wairagde 2 and J. D. Kalambe 1 1 Department of Agronomy, VNMKV Parbhani, India. 431402 2 Department of Agronomy, College of Agriculture Nagpur, 440012. * sunilkinge40@gmail.com Land configurations have a major influence on soil aeration, moisture availability, and temperature of soil which in turn affect the yield and quality of the crop. The broad bed furrow and ridge and furrow are newly developed methods of soybean cultivation in India. Therefore, need for standardized land configuration for the cultivation of soybean in India. Among different conservation measures, Crop residue practices on the soil surface to reduce the evaporation rate and discourage weeds is another water conservation practice in India. To conserve as much rainwater as possible during fewer rainfall years and ways of overcoming excess moisture. The combination of land configuration and crop residue practices conserves soil moisture and improves water use efficiency and grain yield. Hence field experiment entitled “Studies on Land Configuration and Crop Residue Management on Soybean (Glycine max (L.) Merrill)” was conducted at the Department of Agronomy, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during Kharif 2019 to study the effect of land configuration and residue management practices on growth and yield of soybean. Methodology The experiment was carried out in split plot design with three replications consisting of fifteen treatment combinations. The land configuration practices consisted of Flatbed (L1), Broad bed furrow (L2), Ridges & furrow (L3) and five treatments on crop residue management practices of Crop Residue @1.25T ha -1 +5 kg ha -1 decomposing microorganism (CR1), Crop Residue@ 1.25 T ha -1 +10 kg ha -1 decomposing microorganism (CR2), Crop Residue @ 2.5 T ha -1 + 5 kg ha -1 decomposing microorganism (CR3), Crop Residue @ 2.5 T ha -1 + 10 kg ha -1 decomposing microorganism (CR4) and without crop residue control (CR5). 631 | Page Resource conservation and rainfed agriculture
International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Results Among the land configuration treatments broad bed furrow recorded higher growth and yield attributing character. In Land configurations method L2 (broad bed furrow) recorded significantly higher values for plant height, functional leaves plant -1 , leaf area plant -1 , number of branches plant -1 and total dry matter plant -1 than L1 (flatbed) and found at par with L3 (ridges & furrow) in soybean. The increase in seed yield kg ha -1 was attributed to increased growth parameters and yield attributes of soybean. This result correlates with the work of Karande (2006) and Rudrawar (2007). Among the crop residue management practices, the application of Crop Residue @ 2.5 T ha -1 + 10 kg ha -1 decomposing microorganisms recorded higher growth characters and yield attributes. Application of Crop Residue @ 2.5 T /ha + 10 kg ha -1 decomposing microorganism (CR4) produced higher values for plant height, functional leaves plant -1 , leaf area plant -1 , number of branches plant -1 and total dry matter plant -1 than rest of the treatments and found at par with the application of Crop Residue @ 2.5 T ha -1 + 5 kg ha -1 decomposing microorganism (CR3). The increase in seed yield kg ha -1 was attributed to increased growth parameters and yield attributes of soybean. These results correlate with the work of Shelar and Khandekar (2013) and Jadhav et al. (2017). The interaction effect of land configurations and crop residue management practices in growth and growth parameters was found to be non-significant.
