Effect of spacings and levels of nitrogen on growth and seed yield of kharif onion



Effect of spacings and levels of nitrogen on growth and seed yield of kharif onion



Seed Research 1994; 20(2): 147-148



The cultivation of onion in Rajasthan has been hampered by lack of quality seed. Seed production of onion (cv. Agrifound Dark Red) was carried out at Jaipur during the kharif season. The plants were spaced at 45 x 30, 60 x 30 or 60 x 45 cm, and given 4 rates of nitrogen (zero, 40, 80 or 120 kg N/ha), split equally into basal and top dressings. The closest spacing gave the highest seed yield, but the umbel size, and incidence of purple blotch and thrips was not affected by the plant spacing.
