Significance of micronutrients are similarly essential as macronutrients for plant growth and development. Boron has a vital role in biological nitrogen fixation in pulses, which resulted in significant production. Mungbean (Vigna radiata L.) is a primeval and familiar crop among Asian countries due to its dietary and nutritional value. A field experiment was conducted during 2013 at Agronomic Research Area, University College of Agriculture, University of Sargodha, Pakistan to evaluate the efficacy of B in three Mungbean cultivars namely NM-92, NM-11 and AZRI-06 through the application of B in the form of Borax (11%). The B treatments comprised; 0 ppm (Bo), 5 ppm (B1), 10 ppm (B2) and 15 ppm (B3) on growth and yield of mungbean cultivars. Born was applied as foliar on vegetative and reproductive stage. Results revealed that different doses of boron affected the growth and yield of mungbean cultivars. Number of pods per plant, number of seeds per pod, 1000-seed weight (g) and seed yield (t ha-1) was significantly affected by different boron doses. Optimum dose of boron improved the yield whereas dispersion from optimum range yield was reduced. The interaction between boron doses and Mungbean cultivars was also recorded significantly.
