Abstract:
To determine the most suitable sowing date for rapeseed cultivars this study was carried out in Busheshr Agriculture Research Center, Borazjan in 1997-1998 cropping season using a strip plot design with four replications. Rapeseed cultivars were: Global, Regent, Tower, Pf7045/91, Pf5045/88 and Maluka which were sown on four different dates with fifteen days interval (oct.20, nov.5, No. 20 and dec.5). Each plot was four row (3m), with 50cm row distances. Results showed that mean seed yield was highest (1509 kg/ha) when sown on oct.20. Interaction between sowing date and cultivars indicated that Pf7045/91 and Pf5045/88 sown on oct. 20, produced the highest mean seed yield of 2010 and 1840 kg/ha, respectively. Results of correlation studies indicated that grain yield had a positive and significant relation with oil yield, plant height and height of first pod. The heighst correlation was determined between seed yield and oil yield(r=0.99) and there was no significant correlation between the other traits.
