Effect of nitrogen doses and spacing on seed yield of onion (Allium cepa L.) cv. Pusa Red



Effect of nitrogen doses and spacing on seed yield of onion (Allium cepa L.) cv. Pusa Red



Seed Research 30(2): 230-233



The effects of N (0, 40, 80 and 120 kg/ha) and plant spacing (45 x 30, 60 x 30 and 60 x 45) on the yield of onion Pusa Red were determined in a field experiment conducted in Pantnagar, Uttaranchal, India during 1996-98. Plant height, length of flowering stalk, number of umbels per bulb, 1000-seed weight, purple blotch and seed yield increased with increasing rates of N up to 80 kg/ha.
