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

Abstract

A field experiment was conducted during Zaid 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to study treatments consisting of three levels of Molybdenum viz. Mo 1 kg, 1.5 kg and 2 kg/ha and three levels of Sulphur viz. 10, 20 and 30 kg/ha. The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28 %), available N (225 kg/ha), available P (19.50 kg/ha) and available K (92 kg/ha). Ten treatments were replicated thrice and laid out in Randomized Block Design. The results revealed that treatment nine (Molybdenum2kg/ha+ Sulphur 30kg/ha) recorded significantly higher plant height (42.54 cm), number of branches/plants (6.93), number of leaves/plants (15.00), plant dry weight (5.27 g), number of nodules/plants (20.60), number of pods/plant (27.6), number of seeds/pod (9.53), seed yield (1.25 t/ha), stover yield (2.87), harvest index (30.3%), gross returns (87500.00), net returns (47281.52)and B:C ratio (1.18) as compared to other treatments.
