Investigations were undertaken to study the effect of nitrogen in combination with foliar spray of bioregulators and micronutrients on growth and productivity of CO5 black gram. Photosynthetic pigments and foliage soluble protein content were estimated at different phenological phases of black gram. Seed yield were assessed at the time of harvest. Significant increase in the chlorophyll content of the leaf due to basal application of nitrogen 25 kg per hectare with foliar spray of urea 2% and 0.1 ppm brassinolide. The biochemical constituents such as soluble protein content were also greatly enhanced by the basal application of nitrogen 25 kg per hectare with foliar spray of urea 2% and 0.1 ppm brassinolide treatment.
