Abstract
Studies on the performance of Coropulse (a unique emulsifiable concentrate formulation) were taken up on black gram (Vigna mungo). The experiment was laid out in a randomized block design with seven treatments and three replications. The objective was to study the effect of Coropulse toward improving the Rhizobium nodulation and a concomitant increase in the available nitrogen for crop growth and yield. Coropulse at 2.0 mLL−1 of water was sprayed on PU 31 black gram variety on 10, 15, and 20-day-old seedlings for one time and at 10 days followed by 15/20/25 DAS for two times. Coropulse was shown to significantly increase the nodule number as against untreated control at 25 and 49 DAS. Fresh weight of 50 Rhizobium nodules at 49-day age of crop recorded more in Coropulse sprayed plot compared to untreated control at 10 and 25 days of crop growth. Further Coropulse increased leaf area, root length, number of pods plant−1, number of seeds pod−1, 1000-grain weight, and seed yields (18.97 q ha−1) as against untreated control (10.77 q ha−1) that resulted in higher benefit-cost ratio.
