Study of Row Spacing Effects on Yield and Yield Components of Rapeseed (Brassica Napus) Cultivars in Khorramabad

food and edible oil supply is one of the serious problems in the recent years in Iran , About 95% of edible oil is imported ,for this reasns culture of oilseed is imprtant . the experiment was conducted in 1999 / 2000 at research farm of faculty of Agriculture in Khorramabad with six cultivars in three row spacing 15, 30 and 45cm . The experimental design was split plot with three replication . Results showed that: plants height between different row spacing wa significantly (P<5%) and Brian yield between rows was very significantly (P<1%) . Height of cultivars , number of Branch / plant , number of Pod / Plant , number of Seed 1 Pod and weight of 1000 Seed were significantly different (P<5%) . Grian yield between cultivars showed very significantly different (P<1%) . In this experment rows of 15 cm were better than others . The results have showed that narrow row was better than wide rows and so we can use from grain drill of cereal for cultivating colza (Brassica napus).
