A field experiment was conducted during late Kharif 2018 on sandy loam soils at College of Agriculture, University of Agricultural and Horticultural Sciences, Shivamogga, Karnataka, to study the effect of foliar application of water soluble fertilizers on nodule count and microbial population in green gram (Vigna radiata L.). The experiment was laid out in a Randomized Complete Block Design comprising of 3 replications and 13 treatment combinations consisting of three water soluble fertilizers along with package of practice (viz., 2 % DAP, 1 % 19:19:19, 2 % 19:19:19, 1 % monopotassium phosphate, 2 % monopotassium phosphate, 1% 19:19:19 +1 % monopotassium phosphate). All water soluble fertilizers were given as foliar spray at two crop growth stages (30 and 45 DAS). Results showed that foliar application of monopotassium phosphate and 19:19:19 each @ 1 per cent at 30 and 45 DAS along with package of practice recorded significantly higher number of nodules (36.92) at 45 DAS and the same treatment recorded significantly higher bacterial population (49.24 cfu g-1 of soil and 46.12 cfu g-1 of soil at 10-5 and 10-6 dilution, respectively), fungi population (17.13 cfu g-1 of soil and 14.97 cfu g-1 of soil at 10-3 and 10-4 dilution, respectively) and actinomycetes population (10.97 cfu g-1 of soil and 8.93 cfu g-1 of soil at 10-2 and 10-3 dilution, respectively) as compared to other treatments.
