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).
