Abstract

The field experiment was carried out during two successive Rabi seasons of 2021-22 and 2022-23 at the Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.).The treatment combinations of 4 crop residue management, viz. conventional tillage without residue, conventional tillage with residue (3 t/ha rice residue), zero tillage without residue, zero tillage with residue (3 t/ha rice residue) and 5 weed management practices, viz. Triallate 50% EC @ 1250 g a.i. ha-1, Triallate 50% EC @ 2500 g a.i. ha-1, Clodinafop propargyl 15% + Metsulfuron methyl 1% (60 g + 4 g a.i. ha-1),  hand weeding at 20 and 40 days after sowing (DAS) and weedy check in wheat were tested with 3 replications in split-plot design, 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 nutrient content and nutrient uptake followed by conventional tillage with residue. Conventional tillage without residue showed lowest values of on nutrient content and uptake by crop. While in case of weed management practices hand weeding at 20 and 40 days after sowing (DAS) had a significant impact on maximizing nutrient content and nutrient uptake followed by post-emergence application of Clodinafop propargyl 15% + Metsulfuron methyl 1% (60 g + 4 g a.i. ha-1).

Keywords: Field experiment, wheat, cereal crop, nutrient management
