Reduction of seed production cost of onion in India may play an important role in bridging the demand-supply gap of onion bulb in both domestic as well as international market, but choices to be made require appropriate cultural manipulations to reduce the mother bulb requirement, the key cost component of seed production. A field experiment in West Bengal, India was conducted between 2014-15 to 2016-17 on a clay loam (Alfisol) soil to evaluate seed production using five different portions of mother bulb (whole bulb of 70-80g; cross section cut at middle of 40-50g; longitudinally half cut of 35-40 g; longitudinally one third cut of 30-35 g and small but whole bulb of 30-35g) of Sukhsagar variety. Growth, productivity, production cost and net return generally increased with increasing mother bulb size. However, umbels per plant, seeds per umbel, setting percentage, test weight, seed yield and gross return were at par with using whole bulb of 70-80g and longitudinally half cut of 35-40 g. Cost analysis of onion seed production shows 70.86% share alone in procuring mother bulb. Thus, longitudinally half cut reduced mother bulb requirement by 50%. Net return, benefit cost ratio, benefit in terms of rupees or grams per unit rupee investment in mother bulb were higher than that of using whole mother bulb. Based on economic considerations alone, half cut bulb of 35-40 g weight can be recommended instead of using conventional whole bulb of 70-80g weight as cost saving onion seed production options with a possibility of doubling area.
