摘要：

The field experiment was carried out for two years during rabi 1999-2000 and 2000-01 to study the effect of bulb size, cut and uncut bulbs and N levels on seed yield, and yield attributes of onion at Agricultural Research Station, Durgapura, Jaipur. Two years' results indicated that planting of large size bulbs increased significantly the seed yield of 1.5 q/ha over medium size bulbs. Planting of uncut bulbs produced significantly higher seed yield of 15.71 q/ha as compared to that of seed yield obtained under planting of cut bulbs (1/3 upper portion). Increasing levels of nitrogen from 80 to 160 kg/ha significantly increased the seed yield of onion. Application of 160 kg N/ha produced significantly higher seed yield of 16.71 q/ha over 80 kg N/ha.
