A field experiment was carried out to study the suitable water soluble fertilizer and its concentration for spraying on soybean at Regional Research Centre, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Amravati, Mahrashtra during kharif season of the year 2017-18. A set of eight treatments control RDF (30 kg N, 75 kg P2O5 and 30 kg K2O per hectare at the time of sowing) + (No spray), RDF + water spray, RDF + spray of 19:19:19 (0.5 %), RDF + spray of 13:00:45 (0.5 %), RDF + spray of 00:52:34 (0.5 %), RDF + spray of 12:61:00 (0.5 %), RDF + spray of urea (02 %), and RDF + spray of DAP (02 %), were taken (one at flower initiation and second at pod filling stage) under Randomized Block Design with three replication. The experimental results revealed that application of nutritional foliar spray treatment RDF + spray of DAP (2%) recorded significantly higher grain yield (1736 kg/ha) over treatment control RDF + (No spray) (1355 kg/ha) and RDF + water spray (1397 kg/ha) but at par with treatment RDF + spray of 19:19:19 (0.5 %), RDF + spray of 13:00:45 (0.5 %), RDF + spray of 00:52:34 (0.5 %), RDF + spray of 12:61:00 (0.5 %) and RDF + spray of urea (2 %). The same trend was observed in straw yield. Treatment RDF + spray of DAP 2% showed significantly higher gross monetary returns (52155 Rs/ha), net monetary returns (23748 Rs/ha) and B:C ratio (1.81) over treatment control RDF + (No spray) and RDF + water spray but at par with treatment RDF + spray of 19:19:19 (0.5 %), RDF + spray of 13:00:45 (0.5 %), RDF + spray of 00:52:34 (0.5 %), RDF + spray of 12:61:00 (0.5 %) and RDF + spray of urea (02 %).
