Abstract

A field study was carried out during 7th and 8th cycles in conservation agriculture to assess the influence of cropping system {(maize-mustard (MMu) and maize-wheat (MW)}, residue application {(with residue (WR) and without residue (WoR)} and precision nitrogen management options in preceding crop {recommended dose of N (RDN), 33%, 50% and 70% basal RDN + green seeker (GS) based N application} on succeeding summer mungbean. The WR enhanced 17.5% and 13.6% seed yield with 29.1% and 12.06% higher net returns of mungbean in MMu and MW, respectively. Residue mulching with 50+ GS significantly increased the seed protein content. The MMu with WR and 33+ GS produced higher environmental footprints (532.8 and 479.5 kg CO2-e Mg−1), respectively. Similarly, significantly higher gross energy was produced in WR (44.2 × 103 MJ ha−1) while, WoR produced higher net energy (11.7 × 103 MJ ha−1) under MMu compared to MW (43.1 and 8.31 MJ ha−1), respectively. Thus, growing of mungbean under maize-based cropping systems with residue and 50+ GS guided N fertilization to previous crops (maize-wheat/mustard) improved yield and net returns with lower environmentally footprints and energy consumption in Indo-Gangetic plains (IGP) and similar agro-ecologies.
