Impact of residue incorporation and organic manures on basmati rice growth and productivity

Abstract

Incorporation of green manuring of dhaincha and rice residue resulted in better growth and significantly increased the grain yield of wheat and rice crop, respectively. There is increase in soil organic carbon, EC and porosity (%) of soil although decrease in bulk density and soil pH was found due to green manuring and residue incorporation. Available N, (P) and (K) in soil also increased due to incorporation of green manuring and residue incorporation as compared to chemical fertilizers. Incorporation of green manuring and crop residue incorporation results in higher growth attributing characteristics namely plant height, tiller density, number of effective tillers, dry matter production, and panicle length, number of grains panicle-1, test weight, grain yield, and straw yield both rice and wheat crops.
