Coupling of soil and foliar application of fertilizers can be adapted to improve the yield and quality of crops could be a viable option for nutrient management. A field experiment was thus conducted with green gram (CV: NVL-516) in an acidic soil of the Agricultural Research Farm, Siksha ‘O’ Anusandhan, Bhubaneswar in order to study the impact of combined soil and foliar application of nutrients nodular characteristics and yield of summer green gram in Odisha. The experiment was laid out in a Randomized Block Design with three replications and eight treatments consisting of recommended dose of Nitrogen, Phosphorous, Potassium and Sulphur (NPKS) along with foliar application of 2% urea, diammonium phosphate (DAP), KCl, N: P: K (19:19:19) and 1% KNO3 and control. Foliar application was done two times at 30 and 45 DAS. The highest yield (1582 kg ha-1) was recorded in treatment where 1% KNO3 was applied as foliar spray along with the recommended dose of NPKS and was at par with 2% DAP (1574 kg ha-1). There was enhanced nodulation at 45 DAS as a result of increased rhizobial activity under the influence of foliar nutrition of 2% NPK (19:19:19), urea and DAP at 30 and 45 DAS.
