Effect of tillage, residue and residual of nitrogen management on protein yield, factor productivity and nutrient uptake by maize under rice - maize cropping system

Abstract

Field experiment was conducted on effect of tiilage, residue and residual of nitrogen management practices at Institute Research Farm of ICAR – National Rice Research Institute, Cuttack (Odisha) during the rabi of 2016-17 and 2017-18 years. The experiment was laid out in split – split plot design with three replications. The results revealed that significantly higher nutrient uptake (N, P and K), partial factor productivity (nitrogen, phosphorus and potassium), protein yield and productivity of maize was recorded under treatment R3 – RDF + residue mulching (6 t ha-1) as compared R1 – RDF + no residue, but protein content was found non – significant influence by different treatment of maize.
