Abstract:
The experiment was carried out in Kumarganj, Ayodhya, during the rabi season of 2021–2022 at the Agronomy Research Farm of Acharya Narendra Deva University of Agriculture and Technology to examine the effects of preand post emergence herbicides and weed control techniques on the productivity and economics of Indian mustard. In the experiment, fifteen weed management strategies were evaluated. The experiment was set up using a randomized block design with three replications. Application of pendimethalin (PE) @ 1000 g ha-1 + hand weeding at 40 DAS recorded minimum weed density over weedy check and highest weed control efficiency recorded with pendimethalin (PE) @ 1000 g ha-1 + hand weeding at 40 DAS over to other herbicide treatment, and WCI and HEI was highly correlated with WCE. The number of siliquea plants, number of siliquea seeds, length of siliqua, and seed and stover yield were all significantly increased as a result. Maximum net return values (in Rs. Pendimethalin (PE) @ 1000 g ha-1 + hand weeding at 40 DAS was found to be superior to other weed management treatments for B:C ratio (1.33 and 1.69) and B:C ratio (50537 and 64251).
