Abstract: Plant growth substances are well-known to improve the source-sink connection and encourage the translocation of photo-assimilates there by helping in effective flower formation, fruit and seed development and ultimately increase the yield of crops. A field experiment was conducted at VNMKV, Parbhani, MH. during June 2017 to Oct 2017 in a Randomized Block Design (RBD) based on three replications with a view to find out the influence of different plant growth regulators applied at different stages on the growth and yield of soybean cv. Application of plant growth regulators at flower initiation stage (35 DAS) and pod initiation stage (50 DAS) on plant showed significant effect on plant height, number of branches plant-1, chlorophyll content (SPAD value), Dry weight plant-1 and seed yield of soybean. Results showed that spraying of GA3 @ 100ppm produced the higher plant height (43.37cm, 56.72cm, 69.22cm) and higher leaf area observed 6.5dm2, 11.57dm2, 15.53dm2), Spraying of CCC @ 250ppm produced the higher number of branches (3.04, 4.98, 5.87) and same in chlorophyll content and protein content and also gave the highest dry weight (19.16 g plant-1) of soybean at harvest. Results also revealed that Seed yield highest recorded in spraying of TIBA @ 50ppm (21.24q/ha) at par with CCC @ 250ppm and MC 500ppm as compared to other growth regulators. So TIBA acts an important role for increasing soybean yield, when it was applied at 35 DAS and 50 DAS.
