SUMMARY
The present study was conducted during 2022-23 and 2023-24 at research farm, Department of Agronomy, CCS Haryana Agricultural University, Hisar. The experiment consisted of four crop establishment methods and residue management treatments in main plots (T1: Conventional Tillage without residue incorporation (CT-R), T2: Conventional Tillage with residue incorporation (CT+R), T3: Zero Tillage-Permanent beds without residue retention (PB-R), T4: Zero Tillage- Permanent beds with residue retention (PB+R) and five nutrient management treatments in sub-plots (F1: 75% RDF, F2: 87% RDF, F3: 100% RDF, F4: 113% RDF, F5: 125% RDF) accommodated in split plot design with three replications. The dry matter accumulation in PB+R at 60 DAS (444.8 and 455.9 g/m.r.l.), 90 DAS (695.2 and 707.8 g/m.r.l.) and at harvest (805.5 and 819.8 g/m.r.l.) was significantly higher than other crop establishment methods except for PB-R during 2022 and 2023, respectively. Among nutrient management treatments, the maximum dry matter accumulation was found with 125% RDF at 30 DAS (191.6 and 196.6 g/m.r.l.), 60 DAS (437.5 and 442.8 g/m.r.l.), 90 DAS (681.5 and 688.7 g/m.r.l.) and at harvest (788.4 and 811.8 g/m.r.l.) during 2022 and 2023, respectively. The stover yield of maize was significantly higher under PB+R (8788 and 10423 kg/ha) as compared to CT+R and CT-R during 2022 and 2023, respectively. Among different nutrient management treatments, the highest stover yield was obtained with 125% RDF (8554 and 9779 kg/ha). The maximum dry matter accumulation of wheat was recorded under PB+R at 60 DAS (44.9 and 48.1 g/mrl), 90 DAS (207.0 and 222.7 g/mrl), 120 DAS (324.5 and 346.6 g/mrl) and harvest (333.5 and 355.4 g/mrl) during 2022-23 and 2023-24, respectively. Among crop establishment methods and residue management, the maximum straw yield was found with PB+R (6852 and 7007 kg/ha) during 2022-23 and 2023-24, respectively which was significantly higher than CT+R (5820 and 6203 kg/ha) and CT-R (5553 and 5647 kg/ha) during 2022-23 and significantly higher than all the other treatments during 2023-24. It was recorded maximum with 125% RDF (6455 and 6544 kg/ha) which significantly outyielded all other treatments except 100 and 113% RDF during 2022-23 and 2023-24, respectively.
