The experiment was conducted during the kharif season of 2022 and 2023 at Students’ Instructional Farm, Department of Agronomy, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur- 208002 (U.P.) India. The experiment was laid out in in Split Plot Deign with three replications and 16 treatment combination. In Main plot (Crop establishment method) P1- ZT-DSR + Sesbania co- culture, P2- Conventional till-DSR + Sesbania co- culture & Sub plot (Weed management) W1-Oxadiargyl @ 90 g a.i./ha (Pre. Emer.), W2-Pretilachlor 30.7% EC @ 1500-2000 ml/ha (Pre. Emer.), W3- Penoxasulam 1.02% + Cyhalofop - butyl 5.1% OD @ 2000-2500 ml/ha (Pre. Emer.), W4-Pretilachlor 30.7% + Pyrazosulfuron ethyl 0.75% WG @ 2000 g/ha (Pre. Emer.), W5-Oxadiazon @ 500-750 g. a.i./ha (Pre. Emer.), W6 -Oxyflurofen @ 150-250 g/ha (Pre. Emer.), W7-Hand weeding at 15, 30 and 45 DAS, W8-Untreated control. Higher growth attributing characters such as higher plant height, tillers, dry matter accumulation and leaf area index at different crop stages along with maximum grain yield were recorded with ZT-DSR + Sesbania co- culture, and in weed management practices three hand weeding at 15, 30 DAS and 45 DAS significantly enhanced key growth parameters in direct seeded rice.
