  In order to evaluate the effect of direct seeding and transplanting methods on yield and yield components of seven onion cultivars, an experiment was conducted as factorial arrangement in randomized complete block design with four replications in Agricultural Research Station of Minab at 2011. The factors were consisted of culture methods (direct seeding and transplanting) and onion cultivars (602, 611, Mars, Mega, Primavera, Stratus and early White). Sowing in nursery was done in the middle of September and transplants were transferred to main field in the middle of November. Direct seeding was done at October, 22. In the direct seeding method, the transplants were thinned 50 days after sowing and plants distances were regulated 10 cm. Results showed that bolting percent, plant height and bulb shape index in the transplanting method were more than direct seeding method. Regarding, days to bulbing and harvest, transplanting onions were earlier ripening than direct seeding onions. Bulb yield in transplanting method was more than direct seeding method in all cultivars but this difference only was significant in 602, Mega and Stratus cultivars. The 611 and Primavera cultivars were earlier ripening than other cultivars. The lowest bulb yield was recorded in the 611 and Mars cultivars and there was no significant difference between other cultivars. Generally, in the condition of this experiment, transplanting method led to increasing of yield and early ripening of onion. Manuscript profile
