Abstract
In Kharif 2022, a research study was conducted at Crop Research Farm, SHUATS, Prayagraj to investigate the “Influence of nitrogen and weed management practices on yield and economics of Blackgram (Vigna mungo L.)”. The study included three levels of nitrogen (15, 30, and 45 kg/ha) and three weed management practices (hand weeding twice at 20 and 40 DAS, Pendimethalin pre-emergence at 5 DAS, and Imazethapyr post-emergence at 25 DAS). The experiment was designed using a randomized block design with 10 treatments, each replicated thrice. The results indicated that the higher pods/plant (32.13), seeds/pod (8.20), grain yield (1223.33 kg/ha), stover yield (2472.67 kg/ha), lower weed population/m2 (4.06), gross returns (83109.00), net returns (55489.05), and benefit-cost ratio (2.01) were observed in treatment 9, which involved the application of 45 kg/ha nitrogen and 75 g/ha Imazethapyr post-emergence.
