A field experiment was carried out the effect of growth regulator, organic and inorganic foliar nutrition on yield and yield attributes of blackgram. Field experiment was conducted in the department of crop physiology at Vindhya Science & Agricultural Research Institute, Raushar, Rewa (M. P.) during 2014 to 2015. Study the effect of basal application of nitrogen in combination with foliar spray of urea and plant growth regulators. Among the treatments, the basal application of nitrogen 25kg ha^-1 with foliar spray of urea 2% and 0.1 ppm brassinolide significantly expressed the higher values in growth attributes. Among the treatments T₇ performed its superiority and had higher leaf area (102.7, 246.0, 567.0 and 494.3 mg g^-1) at vegetative stage, flowering stage, pod filling stage and harvest stage respectively.
