Effect of dates of sowing and seed rate on sets production of onion (Allium cepa) for raising kharif crop.

摘要

A field study was conducted during the rabi season of 1999-2000 and 2000-01 to determine the suitable date of sowing and seed rate for higher production of onion sets for planting of kharif crop in Jaipur, Rajasthan, India. The treatments consisted of 5 sowing dates, i.e. 15 December, 31 December, 15 January, 31 January and 15 February; and 4 sowing rates, i.e. 12.5, 25.0, 37.5 and 50.0 g/m2. Pooled data revealed that sowing of onion seed on 15 December recorded significantly higher yield of total sets (742.08 q/ha) and optimum size sets (593.63 q/ha) over later dates of sowing and it was found at par with 31 December sowing. Sowing of onion seed at 25 g/m2 resulted in significantly higher yield of optimum size sets, i.e. 377.27 q/ha, over lower and higher seed rates.
