Abstract: A field experiment was conducted during Kharif, 2017 at Agronomy field unit, College of Agriculture, Shivamogga to study the effect of humic substances on nutrient uptake and yield of soybean [Glycine max (L.) Merrill]. The experiment consisted of 10 treatments replicated thrice was laid out in Complete Randomized Block Design. Soybean variety used in this experiment was JS-335. Application of vermicompost on FYM ‘N’ equivalent basis was found superior by recording significantly higher grain yield (1957 kg ha-1)and nutrients uptake (N, P and K) by grain, haulm, total plant uptake and less soil available nutrient status after harvest of the crop. Among humic substances treatments, soil application of humic substances @ 5 kg ha-1 at sowing + foliar application of humic substances extracted from vermicompost (0.2%) at 40 DAS resulted in significantly higher grain yield (1741 kg ha-1) and nutrient uptake of N, P, K by grain, haulm, total uptake and less available nutrient status after harvest of the crop when compared to control.
