A field experiment comprising recommended package of practices (RPP), RPP + soil (2.5 and 5.0 kg ha-1 at 10 DAS), foliar (0.5 and 1.25 % at 45 DAS) application of solubor and combination of both soil and foliar application was conducted during kharif 2017 at the MARS, University of Agricultural Sciences, Dharwad, Karnataka to study the boron nutrition effect on growth, nodulation, yield attributes and yield of soybean in boron deficient Vertisol. A Randomized Complete Block Design was used for the experiment with three replications. The results revealed that RPP along with soil (@ 2.5 kg ha-1) + foliar (@ 0.5 %) application of solubor improved the growth and yield parameters significantly. However, soil application of solubor @ 5 kg ha-1 recorded the highest number of effective nodules per plant (18.64).Seed yield (2806 kg ha-1) response of soybean (16.97 % more yield than RPP) recorded with RPP + soil (2.5 kg ha-1) and foliar (0.5 %) application of solubor was significant except that recorded with soil (5 kg ha-1), soil (5 kg ha-1) + foliar (0.5 %) and only foliar (0.5 %) application of solubor. However, slightly higher benefit cost ratio (2.97) was observed with foliar application of solubor (@ 0.5%).
