Abstract:

Two field experiments were carried out at the Agricultural Research and Experimental Center, Faculty of Agriculture at Moshtohor, Kalubia Governorate, Zagazig University, (Banha Branch), during 2001/ 2002 and 2002 / 2003 seasons to study the effect of three harvest date ( 150, 160 and 170 DAS), four N rates ( 0, 50 ,100 and 150 kg/fed.)and three plant spacing ( 20, 30 and 40 cm) on growth, yield and its attributes and seed quality of canola cv. Pactol. The soil of the experimental field was clay textured with pH value of 8.01 , 19.8 ppm available N , 2.00 % organic matter content and 3.80 % CaCO3. The results showed that growth and yield components did not differ significantly due to different harvesting dates. While, delayed harvest significantly reduced seed yield due to shattering of seeds. Application of 150 kg N/fed produced the highest values of growth characters and yield attributes which resulted in the highest seed yield. Growth , yield and its components significantly increased by increasing plant spacing from 20 to 40 cm between plants. All theeffect of theinteraction between the experimental factor were not significant on all studied characters in both seasons with one exception for the interaction between harvest date and nitrogen rates. Key words : canola, Brassica napus, L , harvest date , N rates and plant spacing.
