Abstract: Bio stimulants are important biological or microorganism origin substances which is intended to use for increase plant nutrient use efficiency and growth process. It is used as organic fertilizer and substitute for synthetic fertilizers. Therefore, to analyse the effect of different bio stimulants on yield and quality of sweet potato, an experiment entitled “Effect of biostimulants on growth, yield and quality of sweet potato (Ipomoea batatas L.) cv. CO-34” was conducted at the vegetable farm, Department of Vegetable Science, College of Horticulture and Forestry, Jhalawar during rabi season 2020-21. The experiment consisted of twelve treatment combinations having four levels each of humic acid (0, 10, 20 and 30 ml/l) and seaweed (0, 1 and 2 ml/l) in Factorial Randomized Block Designwith three replications. There was significant effect of biostimulants (humic acid and seaweed) on growth, yield and quality of sweet potato alone and combination over control. Significant increase in net return (Rs. 225039.30 / ha) and B:C (4.22) ratio was obtained with treatment T11 (Humic acid 30 ml/l and seaweed 2 ml/ l).
