Effect of Different Doses of Sulphur and Vermicompost on Yield and Nutrient Uptake of Black Gram (Vigna mungo L.)

Abstract

The study investigated the impact of varying doses of sulphur and vermicompost on the yield (grain and straw yield) and nutrient uptake (N, P, K and S) of Black gram var. IPU 11-2 at Banda, U.P. A Randomised Block Design (RBD) with three replications and eight treatments were used, comparing different treatments including RDF, and RDF with different levels of sulphur and vermicompost. The results indicated that the application of sulphur and vermicompost i.e., Treatment T8 (RDF+45 kg S (SSP)/ha+3 ton vermicompost/ha), significantly increased both grain (725.33 kg/ha) and straw yield (1673.67 kg/ha) compared to the control. Moreover, it also increased the nutrient content i.e., N- 3.96%, P- 0.96%, P- 0.96% and S- 0.94%. and total nutrient uptake (N- 28.72 kg/ha, P- 6.94 kg/ha, K- 6.96 kg/ha and S- 6.80 kg/ha) in the grain of black gram. These findings suggest that the integrated use of inorganic sulphur along with vermicompost enhances the productivity and nutritional quality of the black gram, offering a more sustainable agricultural practice. The study also provides practical insights for farmers in improving black gram productivity and contributes to the growing body of research on sustainable agriculture.
