The present investigation was undertaken under field condition to study the effect of nutrients and plant growth regulators on growth and productivity of black gram variety CO 5. The leaf nutrient viz., nitrogen, phosphorus and potassium content were estimated at different phenological phases of black gram. Significant increase in the N and P 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 leaf potassium (K) 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.
