Abstract

The current study aimed to investigate at the Agronomy farm (Faridpur) K.N.I.P.S.S Sultanpur, Uttar Pradesh during kharif 2022-2023. The research was conducted in randomized complete block design (RCBD) with 8 treatments, viz. weedy check, one hand weeding at 15 DAS, hand weeding at 15 and 30 DAS, pendimethalin @ 0.75 kg a.i./ha as pre-emergence (W3), quizalofop-ethyl @ 60 g /ha (20 DAS), Imazethapyr @ 60 g /ha (20 DAS), pendimethalin (PE) fb imazathapyr (20 DAS), pendimethalin (PE) fb quizalofop ethyl (20 DAS). Among all the treatments, growth and yield attributes such as pods count/plant (38.17), seeds count pod-1 (8.66) and yield (12.89 q/ha) were obtained highest with hand weeding at 15 and 30 DAS. Furthermore, the concurrent use of pre- and post-emergence herbicides, demonstrated by combinations like pendimethalin (PE) followed by imazathapyr at 20 DAS and pendimethalin (PE) followed by quizalofop ethyl at 20 DAS, yielded outcomes similar to those achieved through manual weeding.
