Abstract:
The effect of nitrogen application on biomass production and yield of legumes and maize under rainfed field conditions was studied to estimate the amount of nitrogen fixed by various leguminous crops under fertilized and non-fertilized conditions and to compare the yield, income and net return of legumes and non-legumes. Yield and biomass of summer legumes were not affected significantly with N application but in case of maize there was an increase of 69 and 74 percent in dry matter and grain yield, respectively. The nitrogen application significantly increased straw yield of summer legumes but had a negative effect on N-fixation at flowering and at pod fill stage.
