In order to obtain the best of sowing date and variety an experiment was conducted with using split- plot design on randomized complete block with three replication in zahk Agricultural Research station of zabol during two cropping seasons( 2005-2006 and 2006-2007). Four sowing date from 10/8/2004 at 15 day interrals was main plot and three spiring rapeseed varieties ( Hyloa40 1 , Y3000,RGS003) were carried sub main plot. The results variance analysis indicated that year effect was significant on seed yield. The results indicative significant differences sowin date on,number of silique in plant, number seed in silique, grain Yield, height, oli yield, during flowering period and during vegetative period in %1 leveI.So that In between sowing dates, the highest seed yield with mean 3396 kglha in sowingdate first" and lowest of seed yield with mean l588kglha in sowing date fourth ( 25/9/ Det4rnber) was obtaind. In within cultivars , Y3000 Hybrid With mean 2562 kglha accompany with Hyola40] had the most seed yield. Intraction effects varieties at sowing date was not significant difference on seed yield and yield components (number of silique in plant, number seed in silique, weight 1000 grain ). With attention to results, the best of sowing date in the early october anduse premature varieties suhc as Hyloa401 , Y3000 and RGS003 is recommend in condition sistan region
