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 experimental soil was clay texture, moderately calcareous in nature and slightly alkaline in reaction and normal in salt content. The results emerged out clearly indicated that the significantly higher plant height (12.2 cm) at 20 DAS, (34.26 cm) at 40 DAS and at harvest (38.80 cm) with treatment T9 (RDF + 00:52:34 @ 0.5%+ GA + SA @ 50 ppm each 27 DAS) foliar spray among all treatments. The significantly higher number of nodules at flowering stage (30-35 DAS) (58.3) were recorded in treatment T10 (RDF + 13:00:45 @ 0.5%+ GA + SA @ 50 ppm each 45 DAS). The significantly higher number of pods plant-1 (28.00) was also recorded in treatment T9 (RDF + 00:52:34 @ 0.5% + GA + SA @ 50 ppm each 27 DAS).
