An experiment was conducted at Horticultural Research Center, Chauras Campus, Department of Horticulture, H.N.B Garhwal University, Srinagar (Garhwal), Uttarakhand to assess the impact of humic acid and ascorbic acid on growth and yield of onion bulb. The experiment was formulated with foliar application of humic acid 0, 30, 50 and 70 ppm and Ascorbic acid 0, 25, 40 and 60 ppm concentration at 30 and 45 days after transplanting with three replications under randomized block design. The maximum plant height (39.44 cm), number of leaves per plant (10), highest bulb length (5.93 cm), bulb diameter (5.47 cm), bulb fresh weight (88.20 g), bulb dry weight (13.88 g) and bulb yield per plot (6.39 kg) were obtained with the spray of Humic acid 70 ppm + Ascorbic acid 40 ppm (T15), while minimum were recorded with control (T1).

Keywords    Humic acid, ascorbic acid, yield, onion.
