Effect of integrated fertilizer use on nitrogen fixation by soyabean crop

Ashok Lodha, U.K. Vaishya, Shahina Tabassum, Smita Singh

Abstract

Integration of fertilizer with organic manure (FYM) significantly increased yields and N uptake by soybean and wheat. Maximum grain yields of soybean and wheat were recorded with treatment 100% recommended dose of NPK+ 15 t FYM over rest of the treatments and control. Highest N fixation by soybean was recorded with 100% recommended dose of NPK+ 15 t FYM. The highest uptake of nitrogen was observed in the treatment 100% recommended dose of NPK+ 15 t FYMby soybean and wheat.
