Abstract:

A field trial was conducted at Karzin flood, Ghir Karzin city, Fars province, Iran, from 2004/ 2005, to determine the effect of sowing date and different tillage methods on the yield and different parts of Canola plant the trial was split plot arranged in randomized complete block (RCB) with three replications. Main plots were tillage and without tillage and subplots were three sowing dates (6. Nov, 16. Nov and 26 Nov. 2004). The trial showed that following results: 1) Different tillage methods and sowing dates and interaction between them on the plant height were not significant differences. 2) The number of sheaths were significant differences at level 5 percent and interaction between them was non significant. 3) The number of seeds in the sheaths on tillage and without tillage treatments were non significant but sowing dates were significant differences at level 5 percent. 4) The effect of different sowing dates on the seed thousand weight were non significant but the effect of different tillage caused that increasing seed thousand weight about 16.47 percent at level one percent. 5) The effect of sowing dates and different tillage methods and interaction between them on the yield of canola were significant differences, respective, at level one and 5 percent.
