Various plant spacing resulted in the increased plant height, onion bulb size, weight of the bulbs, number of the bulbs per plot and yield of the bulbs. In case of different nitrogen levels, all the parameters under the study were significantly affected. However, 12 cm plant spacing with 100 kg N ha -1 gave the best results. Maximum yield of onion bulbs (22.90 and 22.82 t ha -1) was obtained from 12 cm plant spacing with 100 kg N ha -1, respectively.
