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.
