Abstract: The field investigation entitled “Effect of plant growth regulators on growth, yield attributes and yield of soybean (Glycine max (L.) Merrill)” was conducted at experimental farm, Department of Agronomy, College of Agriculture, VNMKV, Parbhani during kharif 2018-19. The experiment was laid out in a randomized block design with nine treatments and three replications with a view to find out the influence of different growth regulators applied at flowering and pod developing stage of soybean. From the result it was revealed that application of seaweed extract (20%) + organic plant extract (80%) at flowering and developing stage recorded higher growth attributes such as plant height (cm), more number of functional leaves, higher leaf area (dm²), higher number of branches, higher dry matter accumulation (g), also yield and yield attributes such as weight of seed plant^-1, number of pod plant^-1, number of seeds plant^-1, seed index (g), seed yield kg ha^-1, straw yield kg ha^-1, harvest index % and it was at par with organic plant extract and brassinosteroides (0.01%) + organic plant extract.
