Abstract

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.
