Tillage and residue management on nutrient uptake by wheat under rice-wheat cropping system

Abstract

A 2-year field experiment was carried out to investigate the effects of tillage and residue management practices on yield and NPK uptake by wheat under rice wheat cropping system at Birsa Agricultural University, Ranchi, Jharkhand. There were four tillage practices and four residue management practices arranged in split plot design with three replications. Higher NPK uptake by wheat, protein productivity, grain and straw yield as well as yield attributes viz., number of spikes m-2, number of grains spike-1 and 1000-seed weight (g) recorded under conventional tillage wheat sown after conventional tillage rice (CTCT) and residue retained in both crops (R-R) whereas lower recorded under zero tillage wheat sown after zero tillage rice (ZT-ZT) and without residue retained in both crops (NR-NR) during both the year of experimentations.
