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

A field experiment was conducted during zaidseason of 2022 at the crop research farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Science, Prayagraj (U.P) India. To study Response of Sulphur and zinc on growth and yield of Zaid blackgram. The experimental treatments consists of sulphur concentrations 20,25,30,kg/ha And zinc 5,10,15,kg/ha . There were 10 treatments each replicated thrice. The soil of each experiment plot was sandy loamy, slightly alkaline (pH 7.8), low in organic corbon (0.35%) available N(163.42kg/ha), available P(21.96 kg/ha)and available K (256.48 kg/ha). Results revealed that at higher plant height (39.80 cm), number of branches/plant(5.00), number of Nodules/plant(41.50), plant dry weight (4.85g/plant), pods/plant (37.36), seeds/plant (7.00), test weight (37.14g/plant), seed yield (13.63t/ha), stover yield (19.68t/ha), and harvet index (40.79 %). were significantly influenced with application of sulphur 30kg/ha +zinc 15kg/ha. Higher gross returns (INR 107670/ha), higher net returns (INR 74538.11/ha) and higher B:C (2.24) were also recorded in –treatment 9(sulphur 30kg/ha+zinc15kg/ha).
