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 ā€˜Nā€™ equivalent basis was found superior by recording significantly higher grain and haulm yield and nutrient uptake of N, P, K by grain, haulm, total uptake and less available nutrient status after harvest of 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 and haulm yield 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.
