A field experiment was carried out to study the impact of application of water-soluble fertilizers at different growth stages on growth and yield of soybean at Experimental Research Farm, College of Agriculture, Latur during kharif season of the year 2021-22. A set of nine treatments viz., T₁-Control, T₂-RDF, T₃-RDF+19:19:19 @0.5% at 30 DAS, T₄- RDF + 00:52:34 @1.0% at 45 DAS, T₅- RDF + KNO₃ @1.0% at 60 DAS, T₆- T₃ + T₄, T₇- T₄ + T₅, T₈- T₃ + T₅ and T₉- T₃ + T₄ + T₅ were taken out for the field experiment under Randomized Block Design with three replications. The experimental results revealed that application of treatment T₉ which received foliar spray of 19:19:19 @0.5% at 30 DAS + 00:52:34 @1.0% at 45 DAS + KNO₃ (13:00:45) @1.0% at 60 DAS along with RDF recorded significantly higher growth parameters viz., plant height (71.66 cm), number of branches plant^-1 (9.55) at harvest stage, number of leaves plant^-1 (61.70) at 60 DAS and total chlorophyll content (10.66 mg g^-1 fresh weight) in soybean at 45 DAS. The similar trend was observed in case of yield attributes viz., Number of Pods plant^-1 (75.70), Number of seeds pod^-1 (3.68) and seed yield (2206.52 kg ha^-1) and straw yield (3444.27 kg ha^-1) with the application of T⁹ which was found at par with treatment T₆ which receives foliar application of 19:19:19 @0.5% at 30 DAS+ 00:52:34 @1.0% at 45 DAS along with RDF.
