Field experiment was conducted in the Dept. of Agronomy at Tamil Nadu Agricultural University, Coimbatore, to study the effect of organic and inorganic foliar nutrients on the performance of blackgram during summer 2002. The results revealed that the growth parameters viz., plant height, leaf area index, drymatter production and yield attributes viz., number of flowers plant-1, number of pods plant-1, number of filled grains pod-1 and grain yield were significantly higher in the foliar treatment of 1% Urea spray at floral initiation and 15 days after flowering. This was on par with the treatment of 2% DAP spray with regard to the yield parameters. To conclude, foliar spray of 1% Urea or 2% DAP at 35 and 55 DAS can be recommended to increase the productivity of blackgram.
