Influence of Nitrogen and Weed Management Practices on Yield and Economics of Blackgram (Vigna mungo L.)

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.

Influence of Various Nitrogen Levels and Herbicides Application on Nutrient Uptake and Quality Parameters of Rice (Oryza sativa L.)

“…This might be due to effective control of weeds reduce the crop weed competition, increased maximum availability of moisture, nutrient, space and light, to the plant resulted in higher crop growth and protein yield. Shekara et al [15] also reported the similar type of responses [16][17][18][19][20].…”
