Abstract
A research trail was conducted in Kharif 2022, at Crop research form, SHUATS, Prayagraj. To study the “Effect of nitrogen and weed management practices on growth and yield of Blackgram” (Vigna mungo L.). The treatments consist of three levels of nitrogen (15, 30 and 45 kg/ha) and weed management practices (Hand weeding twice (20 & 40 DAS), Pendimethalin (0.75ml/ha) Pre-emergence (5 DAS), Imazethapyr (75g/ha) Post-emergence (25 DAS) are included. Experiment were laid out in randomized block design with 10 treatments each replicated thrice. The result showed that viz: significantly higher plant height (64.49 cm), number of nodules/plant (23.80), number of branches/plant (6.40), 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) recorded in (treatment 9) Nitrogen (45 kg/ha) + Imazethapyr (75 g/ha) Post-emergence.
