| Abstract The experiment was conducted out at the College of Agriculture and Forestry Farm-Mosul University, In loam soil during the seasons 2011 ـ 2012 and 2012ـ 2013 to study the effect of three levels of organic fertilizer (0, 10 and 20 ton .ha-1) and four phosphorus fertilizer levels (0, 25, 50 and 75 kg P2O5 .ha-1) on growth and yield of rapeseed. The experiment was arranged in Split Plots design with three replicates. The results showed that a significant superiority in : plant height, no. of branches. plant-1, leaf area index, no. of siliqua. plant-1, no. of seeds. siliqua-1 ,1000 seed wt., seed yield, seed oil percentage and oil yield, for both seasons in the treatment of 20 ton. ha-1 of organic fertilizer adding to the soil. Using phosphorus fertilizer with 50 kg P2O5 .ha-1 gave a significant superiority in the previous traits. The interaction of 20 ton. ha-1 organic fertilizer with 50 kg P2O5 .ha-1had gave a high significant values for : no of siliqua. plant-1, (211.2, 238.3 siliqua) no. of seeds. siliqua-1 (21.1 , 22.5 seed), seed yield (1118.4 , 1252 kg.ha-1), and oil yield (485.3, 550.9 kg.ha-1) for seasons 2011 ـ 2012 and 2012 ـ 2013 respectively. | ||
