Effect of Nitrogen and Zinc Levels on Growth and Yield of Black Gram (Vigna mungo L.)

To study the retaliation performance of Nitrogen and Zinc on growth, yield and yield attributes of black gram (Vigna mungo L.) During the Zaid season of 2021, a field experiment was carried out at the agricultural research farm of SHUATS, Prayagraj, to analyze the influence of nitrogen and zinc levels on the growth and yield of a Black gram. The experiment was conducted in a randomized block design (RBD) it was carried with Nine treatments, each treatment have three replications and we observed each treatment on the bases of one-year experimentation. In view of this experiment three Nitrogen levels, i.e.N1 - (15 kg/ha), N2 – (20 kg/ha) and N3 – (25 kg/ha) and Zinc levels, i.e., Zn1 – (0.25 %), Zn2 – (0.5 %), Zn3 – (0.75 %) .The results was obtained that the treatment with the application of N 25 kg/ha+ Zn 0.5% was observed significantly maximum plant height (41.50 cm), number of nodules per plant (25.50), number of branches per plant (7.65), plant dry weight (9.61 g/plant), pods per plant (37.55), seeds per pod (6.83), test weight (39.23 g), grain yield (937 kg/ha), stover yield (2418 kg/ha). Maximum net return (Rs42008.92/ha) and B:C ratio (2.22) were recorded with treatment of N 25 kg/ha+ Zn 0.5%.This study concluded that the maximum grain yield (937 kg/ha) was acquired with application N 25 kg/ha+ Zn 0.5%, significantly superior to the rest of the treatments.
