Abstract: Promising kharif onion cultivars or breeding lines developed at different at different Agricultural Universities and National Research Centre for Onion and Garlic, Pune have been evaluated under different temperature regimes by three plantings in field condition under tropical-humid conditions to assemble the basic information on the possibility of growing onion under early rabi condition in the Gangetic plain of West Bengal. Average day/night temperature of 20o to 21 oC coupled with rainless condition has been found suitable for growing early onion in the humid condition in the Gangetic alluvial region of West Bengal. Growing early-rabi onion with planting of seedlings in the first week of October employing the varieties like, Baswant 780, Agrifound Dark Red, Arka Pragati and Phule Safed and harvesting the bulbs during last week of February appeared to be the best.
