Abstract

A Field experiment was conducted to study the effect of different levels of sulphur on growth and yield of onion under drip irrigation on years (2013-2014) at RHREC, College of Horticulture, Bangalore. The experiment was conducted with a Randomized block design with four replications. The treatments comprised of 7 combinations (0, 15, 30, 45, 60, 75 and 90 kg S/ha) in which sulphur was supplied through gypsum. The results indicated significantly higher bulb yield (61.96t ha-1) and yield components like average bulb weight, bulb yield per plot and marketable bulb yield was obtained due to application of recommended dosage of fertilizer plus 45 kg S ha-1. The growth components viz., plant height, number of leaves, collar thickness and neck thickness showed significant with the application of result in the recommended dosage of fertilizer plus 45 kg S ha-1. Compared to other levels of sulphur.
