The study looked at how different farming practices affect soil and crop growth in greengram plants. They found that using zero-tillage with crop residue helped improve soil quality and increase crop yields. Adding residue to the soil also boosted the productivity of greengram plants. Traditional tilling methods without residue led to lower soil fertility and crop yields. Overall, using conservation agriculture techniques like zero-tillage with residue and weed management can be profitable for growing greengram crops.
