Abstract

An experiment was conducted at Sukranagar, Chitwan to assess the effect of nitrogen (N) and off season bulb size on seed production of onion cv. Bemausami-1 (N-8293) during 2009/10. Five levels of nitrogen (0, 40, 80, 120 and 160 kg N/ha) as main plot factor and three bulb size (<1, 1-3 and >3 cm diameter) as sub plot factor were used as treatments and laid out in a split plot design with three replications. Plant height, number of tillers, leaves; scapes, umbels, and flowers per plant were significantly high at higher doses of nitrogen and similar results were found at the bigger sized bulb too. Seed yield was the highest (300.2 kg/ha) at 160 kg N/ha and >3 cm bulb size and the lowest (200.1 kg/ha) at 0 kg N/ha and <1 cm bulb size. B: C ratio was the highest (1.79) at 160 kg N/ha with medium sized bulb (1-3 cm) and the lowest (1.05) at 0 kg N/ha with bulb size of < 1 cm.
