A field experiment was conducted during Kharif seasons of 2017 at Zonal Agricultural Research Station (ZARS), in Gandhi Krishi Vigyan Kendra (GKVK), University of Agricultural Science (UAS), Bengaluru on red sandy clay loam soil which was medium in available NPK, to evaluate the effect of water soluble fertilizers on growth attributes of soybean crop. The experiment was laid out in a RCBD design with three replications and 10 treatments. Water-soluble fertilizers (WSF) (NPK: 19: 19: 19) was used at different growth stages with 1.5 %, 2 % and 2.5 % concentration. Significantly higher yield parameters like number of pods plant-1 (75.70), seed yield plant-1 (28.27 g), seed yield (3250 kg ha-1), haulm yield (7129 kg ha-1), harvest index (0.313), higher net returns (Rs. 70766 ha-1) and higher B:C ratio (3.64) were obtained with the treatment recommended dose of fertilizer (RDF) + spraying of water-soluble fertilizer at 2.5 % at flowering + pod formation stage at 60 DAS, compared to other treatments.
