An experiment was carried out in sandy loam soil at M. G. C. G. Vishwa Vidyalaya Farm, Chitrakoot during kharif of 2013. The objectives were to evaluate the effect of zinc (Zn) and boron (B) on the yield, nutrient content and quality of blackgram [Vigna radiata (L.) Wilczek] and to find out the optimum dose of Zn and B for yield maximization. There were four levels of zinc (0, 10, 20 and 30 kg/ha) and boron (0, 2.0 kg/ha one spray with boric acid and 2 kg/ha two sprays with boric acid) along with a blanket dose of N20 P40 K20 kg/ha. The experiment was laid out in factorial randomized block design with three replications. Results showed that the application of 30 kg zinc/ha and boron 2 kg/ha with two foliar sprays resulted in highest grain yield with their interaction effect on grain yield (8.98 q/ha) as well as all growth, yield, quality and nutrients uptake parameters. The lowest value of symbiotic traits, yield parameters, quality and uptake status were recorded under control treatments. Increasing dose of zinc and boron increased the all parameters.
