Abstract :This study aimed to provide the placement of rapeseed in the present production system and to determine the best conven-ient sowing date for rapeseed in the intersection zone of Blacksea region. The research was conducted in Merzifon county of Amasya province between 1998-2001 years in accordance with randomized complete block design with four replications and separately for each cultivar. Three rapeseed cultivars (Capitol, Eurol and Bristol) which are winter type were used as material and six sowing dates (September20, September 30, October 10, October 20, October 30, November 10) were tested. Plant height, 1000 seeds weight, branch number and seed yield were examined in the study. As a result of the study, maximum yields were obtained from Capitol sown September 20 with 4135 kg/ha, from Eurol sowing September 30 with 4810 kg/ha and from Bristol sown September 30 with 3770 kg/ha. It was concluded that because delayed sowind for winter rapeseed resulted in decreasing seed yield, winterrapeseed must be sown up to October10.Keywords : Kolza, ekim zamanı, çeşit, verim
