While transplanting onions is practiced widely in tropical and temperate regions, in Jamaica this practice is unconunon as an alternative method of planting. A study was conducted at the BodIes Research Station from September 1997 to March 1998. to determine the optimum transplant age for bulb yield, and to compare yields of direct seeded and transplanted onions. Yields of the former were higher but the difference was not significant(p;oO.0092).Highly significant interactions ofmean yields among cultivars were found. At both transplanting dates, significantly higher percentages ofdouble bulbs were produced with direct seeding. The survival rate ofplants was highest for direct seeding (81%) and lowest for transplanting at six weeks (66%). There were significant differences between planting methods and among cultivars with respect to bulb size.
