Abstract:
An experiment was conducted at Instructional Farm of Department of Agronomy, Faculty of Agriculture, AKS University, Sherganj, Satna (M.P.) during Kharif season of 2021-22. The experiment consisted of randomize block design having with three replications. In this experiment, 12 treatment The treatments consisted of weedy check, control, weed free plot, Pendimethalin 30 EC @ 850 ml/ha + hand weeding, Diclosulam (strong arm) @ 80 gm + hand weeding, Chlorimuron – ethyl 9% EC @ 67.5 ml/ha, Fenoxaprop-p-ethyl 9% EC @ 67.5 ml/ha, Chlorimuron-ethyl 25% WP @ 9.37 gm/ha + Fenoxaprop-p-ethyl 9% EC @ 67.5 ml/ha, Quizofop-p-ethyl 5% EC, Imazethapyr 5% SL @ 50 ml/ha, Chlorimuron 25% WP @ 2 kg/ha, Propaquizafop + Imazethapyr and Alachlor at 1 kg/ha. During the experimentation was observed that the maximum and significantly higher grain yield (10.39 q/ha), gross return (Rs. 91998.00/ ha) as well as highest B: C ratio of 2.73:1. While highest net returns (R.s 65824.00/ ha) was obtained with Chlorimuron – ethyl 9% EC @ 67.5 ml/ha, due to lower cost of inputs comparison to others. Hence, it can be concluded that weed free treatment with B:C ratio 2.7 can be used as an effective weed management in integrated manner to chemical treatment subjected to unavailability and insufficient of labour.
