comparison of different propagation methods on yield and quality of two onion cultivars

this study was conducted to compare different propagation methods and two cultivars (azarshar red, and kashan white) as a rcbd in factorial with four replications in shirvan in 2001. in azarshar red onion, high yield belonged to sets method that 30 percent more than seed sowing. in kashan white bulb cultivar, high yield was get from seedling cultivation and there were no significant differences with the other two cultivation methods. bulb weight decreasing in store was shown high significant difference and in azarshahr red onion cultivar minimum was due to sowing and maximum was due to seedling cultivation. in kaslian white cultivar seedling cultivation methods had minimum bulb weight decreasing and maximum value due to sowing. in azarshahr red cultivar maximum dry matter was get from sowing whereas, in kashan white cultivar was gets from sets cultivation.
