Soybean (Glycine max (L.) Merr.) is one of the major oilseed crops in the world. A study was conducted at Main Agricultural Research Station, University of agricultural sciences Dharwad. Plant biostimulants contain substance(s) and/or micro-organisms when applied to plants stimulate natural processes to enhance/benefit nutrient uptake, nutrient efficiency, tolerance to abiotic stress and crop quality. 1^st spray of biostimulants was taken up 5 days prior to the flowering, and the crop was in pod formation stage on 52 DAS, 8 days later 2^nd spray of biostimulant was taken up. Significantly higher growth parameters such as leaf area (11.47 dm2 plant^-1), leaf area index (3.82) and dry matter accumulation (72.25 g plant^-1), between 30-60 DAS, AGR (2.062 g day^-1) and CGR (68.72 g m^-2 day^-1) and between 60 DAS to harvest, AGR (0.211 g day^-1), CGR (7.02 g m^-2 day^-1) and biomass duration (1239.7 g days plant^-1) were recorded with foliar application of Crop Max @ 750 ml ha^-1 at flower initiation followed by Biozyme @ 625 ml ha^-1 at pod formation (T8). Crop Max as a biostimulant @ 750 ml ha^-1 followed by Biozyme @625 ml ha^-1 has a significant influence on the growth parameters and growth indices.
