Performance of Black gram (Vigna mungo L.) as influenced through the application of Zn, B, and Mo

An experiment was conducted in the wire net house of the Department of Crop Physiology, C. S. Azad University of Agriculture and Technology, Kanpur, during the Kharif season of the year 2019. The experiment was conducted to find out the effects of Zn, B, and Mo combinations on growth, yield, and attributes of Black gram laid out in CRD with 7 treatments and 3 replications. The study found that black gram grown with T7-Zn +B + Mo @ 0.5% + 0.2% +0.1% grew significantly better, as evidenced by taller plants (33.65 cm), more leaves/plant (12.55), more branches/plants (7.77), dry weight of the leaves/plant (4.41g), number of nodules/plants (10.72), number of pods/plants (25.99), dry weight of pod/plant (16.86 g), dry weight of stem/plant T₇-Zn +B + Mo @ 0.5% + 0.20% + 0.1% also increased leaf area per plant (121.75 & 196.98), chlorophyll intensity (46.15 & 34.10), days to 50% flowering (59.10), days to pod formation (64.20), grain yield per plant (3.45 g), and protein content (21.89%). In the same way, yield characteristics (number of seeds per pod, number of seeds per plant, and weight of 1000 seeds in grams) were also significantly higher with the same treatment.
