Effect of Fym and Sulphur Application on Nutrient Availability In Soil Growth and Yield of Urdbean

Abstract

A field experiment was conducted to assess effect of FYM and sulphur on nutrient availability in soil and growth at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.), during kharif season of 2020. In the seven treatments consistent application of FYM and sulphur viz., Control, RDF, RDF + FYM @ 2.5 t ha-1, RDF + S @ 10.0 kg ha-1, RDF + FYM @ 5.0 t ha-1, RDF + S @ 20.0 kg ha-1 and RDF + FYM @ 2.5 t ha-1 + S @ 10.0 kg ha-1 were tested in RBD with three replications. Shekhar-2 was grown as a test variety. The results revealed that the combined application of FYM and sulphur exhibited significant influence on the growth, yield attributes and yields of urdbean as compared to control during year of experimentation. Significant improvement in growth parameters viz. plant height, number of branches plant-1, number of trifoliate leaf plant-1, dry matter accumulation (g plant-1), number of root nodules plant-1, dry weight of nodules (mg plant- 1), protein content, 1000-grain weight, nutrient content and grain yield was recorded with the application of RDF + FYM @ 2.5 t ha-1 + S @ 10.0 kg ha-1, which established its superiority over rest of the FYM and sulphur treatments. The total nitrogen, phosphorus, potassium and sulphur uptake (94.53, 15.63, 61.31 and 9.23 kg ha-1, respectively) by urdbean crop was also highest with the application of RDF + FYM @ 2.5 t ha-1 + S @ 10.0 kg ha-1 and 91.63 and 42.06% increase in grains and straw yield of urdbean was recorded in the same treatment. The application of RDF + FYM @ 2.5 t ha-1 + S @ 10.0 kg ha-1 resulted in higher protein yield (274.58 kg ha-1). Thus the application of RDF + FYM @ 2.5 t ha-1 + S @ 10.0 kg ha-1 was found better for sustainability of urdbean
