The purpose of this experiment was to find the most suitableplam densityof two rapeseed varieties in this area. The study was carried out as a split plot design using randomized complete block with four replications in fall season in Agriculture Research,Center,Borazjan in 2000-2001 The main plots consisted of wo rapeseed varities (pf7045/91,option500) and subplot was including 4 intra row (2.5,5, 7.5,10cm) treatments were planted in tlie farrows with inter row30 cm . Acording to the results of combined analysis were performed on data/There was significant differenc at 1% level observed between cultivars and significant differences observed between intra row at 5% level and other factors no significant . Comparison of mean by DMRT indicated .that the highest yield obtained from option500 in intra row 7,5 cm with 2896kg/ha , least yield from that variety was pf7045/91 (2.5cm) with 1521kg/ha.Therefore option500 is suitable cultivar and intra row between 5-7.5cm are recommended for Bushehr province.
