EFFECT OF PLANT DENSITIES AND CULTIVARS ON YIELD COMPENENTS OF RAPESEED (Brassica napus L.) UNDER DRY LAND FARMING IN IRAQI NORTHERN
The experiment was conducted at the college farm of Agriculture and Forestry – Mosul Univ . for two seasons 2005/2007 , to determine the effect of three plants density (500000 , 333333 and 250000 plants ha-1) with two cultivars (pactol and shiralee) on growth and yield of rapeseed under semi arid co...

| Summary: | The experiment was conducted at the college farm of Agriculture and Forestry – Mosul Univ . for two seasons 2005/2007 , to determine the effect of three plants density (500000 , 333333 and 250000 plants ha-1) with two cultivars (pactol and shiralee) on growth and yield of rapeseed under semi arid condition. The results showed that superiority of no. of seeds/siliqua , seed yield , oil percentage and oil yield with500000 plants ha-1 for both seasons . Pactol cultivar was superior on no. of siliqua/plant , wt. of 500 seeds , seed yield, oil percentage and oil yield for both seasons. The interaction of 500000 plants ha-1 with pactol cultivar gave excellent result on seed and oil yield , which increased up to 4796 and 1759.4kg ha-1 in the first season and up to 3835.3 and 1325.3kg ha-1 in the second season . Correlation between no. of seeds/siliqua and wt. of 500 seeds had positively related to no. of siliqua/plant, while oil yield correlated positively with the seed yield for both seasons . |
