Abstract
The present study was stimulated by the problem of onion seed production where seed production is possibly only winter period after which rapid increase in temperature as well as early shower adversely affect the quality of seed. The experiment was laid out in a randomized complete block design with four replications to determine the effect of vernalization on the yield and quality of onion seeds. Four treatments viz. V1= 10°C, V2= 12°C, V3= 15°C and V4= 30 ± 2°C (control temperature) were consisted to achieve the objective. The research work was done at On-Farm Research Division, BARI, Bogra during September, 2011 to June, 2012. The results revealed that the growth parameters, seed yield components, health and quality of harvested seeds were significantly influenced by the different treatments. Results showed that among different treatments, vernalized at 12°C for 45 days produced high yield of quality seeds of onion at Bogra region in Bangladesh.
