Abstract

The field experiment was conducted during two successive Rabi (winter) seasons of 2021-22 and 2022-23 at the Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.). Twenty treatment combinations comprised of 4 crop residue management, viz. conventional tillage without residue, conventional tillage with residue (3.0 tones ha-1 rice residue), zero tillage without residue, zero tillage with residue (3.0 tones ha-1 rice residue) and 5 weed management practices, viz. Triallate 50% EC PE @ 1250 gm a.i. ha-1, Triallate 50% EC PE @ 2500 gm a.i. ha-1, Clodinafop propargyl 15% + Metsulfuron methyl 1% WP PoE(60 gm + 4 gm a.i. ha-1), hand weeding at 20 and 40 DAS and weedy check in wheat were tested in split-plot design with 3 replications, keeping crop residue management in main plots and weed management practices in subplots. Among the different crop residue management, zero tillage with residue was found most effective in maximizing yield attributes and yield of timely sown wheat followed by conventional tillage with residue. Conventional tillage without residue showed lowest values of yield attributes and yield of wheat crop. While in case of different weed management practices hand weeding at 20 and 40 DAS had a significant impact in maximizing yield attributes and yield closely followed by post emergence application of Clodinafop propargyl 15% + Metsulfuron methyl 1% WP PoE(60 gm + 4 gm a.i. ha-1).
