Abstract: The present study was stimulated by the problem of onion seed production where seed production isrnpossibly only winter period after which rapid increase in temperature as well as early shower adverselyrnaffect the quality of seed. The experiment was laid out in a randomized complete block design with fourrnreplications to determine the effect of bulb size on the yield and quality of onion seeds. Three treatmentsrnviz. B1= 10 g, B2= 15 g and B3= 20 g were consisted to achieve the objective. The research work wasrndone at On-Farm Research Division, BARI, Bogra during September, 2011 to June, 2012. The resultsrnrevealed that the growth parameters, seed yield parameters, health and quality of harvested seeds werernsignificantly influenced by the different treatments. Results showed that among different treatments,rnoptimum bulb size is 15 g for production true seeds of onion at Bogra region in Bangladesh.
