Abstract: A field experiment was conducted at the Research Farm, School of Agriculture, ITM University, Gwalior, (M.P.) during the kharif season of 2019-20. A set of 12 treatment combinations including four phosphorus levels viz., 0 kg/ha (P₀), 20 kg/ha (P₁), 40 kg/ha (P₂) and 60 kg/ha (P₃) with three Sulphur levels viz., 10 kg/ha (S₁), 20 kg/ha (S₂) and 30 kg/ha (S₃) were evaluated. Treatments were replicated thrice as per Randomized Block Design with Factorial concept. Crop sown with application of phosphorus @ 60 kg/ha combined application with Sulphur @ 30 kg/ha attained significantly higher plant growth and yield at all the growth stages of plant. The significantly higher plant height, number of branches as well as leaves per plant, number of root nodules per plant, grain and stover yield per hectare of black gram at maximum crop growth stage was recorded under the application of phosphorus @ 60 kg/ha combined application with Sulphur @ 30 kg/ha with the respective values of 23.69, 42.72cm, 11.78,9.92,20.76,15.12 q/ha and37.72 q/ha, respectively proved significantly superior to rest of the treatments. Result showed that black gram variety when sown the application of phosphorus @ 60 kg/ha combined application with Sulphur @ 30 kg/harecorded the maximum and significantly higher values of these parameters.
