The experimental soil was clay texture, moderately calcareous in nature and slightly alkaline in reaction and normal in salt content. A field experiment was conducted to study the “Effect of water soluble fertilizer with growth regulator on growth, yield and quality of black gram grown on Vertisol” at the farm of Department of Soil Science and Agril. Chemistry, College of Agriculture, Badnapur during kharif 2019-2020. The experiment comprised of ten treatments with three replication which included the foliar spray of water soluble fertilizer and growth regulator and RDF application through soil at the time of sowing. The results emerged out clearly indicated that application of RDF + 00:52:34 @ 0.5%+ GA + SA @ 50 ppm each 27 DAS significantly increases growth parameters, such as plant height, leaf area and number of root nodules of black gram. The application of foliar nutrition helps to overcome the specific occurrence of stress and as a result of maximum vegetative growth due to optimized nutrition of the plant. Application of RDF + 13:00:45 @ 0.5% + GA @ 50 ppm 27 DAS significantly increases nutrient uptake of nitrogen and application of RDF + 00:52:34 @ 0.5%+ GA + SA @ 50 ppm each 27 DAS significantly increases nutrient uptake of phosphorus and potassium.
