| Abstract | ||
| Three field experiments were carried out in the Experimental Station of Desert Research Center at Maruyt, Western Delta during 2C01, 2002 and 2003 winter seasons, respectively to study the effect of sowing methods (direct seeding and transplanting), applying three levels of ammonium sulphate (0, 20 and 40 kg N per feddan) and two amounts of compost (0 and 10 m3 per feddan), on growth, yield and its components of canola (Brascia napus L ) of Pactol variety. Using the transplanting technique for canola cultivation under the new reclaimed soil conditions led to increase significantly all *tudied growth characters i.e. (plant height! cm, plant fresh and dry weight! 9, leaf area index “LAM, total pigments, total chlorophyll, and yield and its attributes i.e. plant survival at harvest (0/0), no, of branches per plant. no. of seeds per siliqua, weight of seeds per siliqia (mg), biological yield toni'fed., seed yield tonffed, 1000 seed weight (9), oil % and oil yield tonifed). Canola growth characters, yield and its components, survived plants% at harvest and seed oii% were significantly increased by increasing N fertilization up to 40 kg Ni fed as ammonium sulphate (20.5 % N). Applying compost as soil amendment significantly increased canola growth characters, yield and its components in addition to percentage of survival plants at harvest. First and second orders of interactions in general increased all the studied characters significantly. Higher observations obtained from the combination of (transplanting x 40 kg fed), (transplanting x 10 malfed of organic manure), (10 maffed of organic manure x 40 kg Nifed) and (transplanting x 10 malfed of organic manure x 40 kg N/fed). | ||
