Production efficiency and nutrient uptake by rice as influenced by tillage, residual effect of residue and nitrogen management practices under conservation agriculture

Abstract

The field experiment was conducted during kharif season 2016 and 2017 at Research Farm of ICAR - National Rice Research Institute, Cuttack (Odisha) to study the effect of tillage, residual effect of residue and nitrogen management on nutrient uptake, partial factor productivity and production efficiency of rice. Findings revealed that tillage, residual effect of residue and nitrogen management had significant on yield, nutrient uptake, Partial factor productivity and production efficiency of rice. Treatment conventional tillage (CT), RDF + residue mulching (6 t ha-1) and LCC based (100% RDN) registered significantly the highest grain yield, nutrient uptake (N, P and K), partial factor productivity and production efficiency in comparison to their respective treatments.
