Effect of foliar application of water soluble fertilizer on nutrient uptake and economics of soybean (Glycine max L. Merrill)

Abstract

The field experiment was conducted during 2016-17 at Zonal Agricultural Research Station GKVK, Bengaluru to study the effect of water soluble fertilizer on nutrient uptake and economics benefits of soybean (Glycine max L. Merrill). The experiment was laid out in Randomized Complete Block Design with seven treatments replicated thrice. Recommended dose of fertilizer (RDF) in combination with foliar spray of macro nutrients were taken into study. The results revealed that RDF + foliar application of WSF @ 2 % at flowering and pod filling stage recorded significantly higher nutrient uptake viz., nitrogen uptake (121.53 kg ha-1), phosphorus uptake (16.74 kg ha-1), potassium uptake (107.50 kg ha-1), and higher net returns (₹ 50526 ha-1), benefit cost ration (2.71) was recorded with significantly higher values.
