| Abstract | ||
| This study was conducted in the Eexperimental Farm, Faculty of Environ. Agric. Sci., EL-Arish city, Suez Canal University during two seasons of 2011 and 2012. Sunflower cultivar (Sakha53) was provided by Oil Crops Research Department, Field Crop Research Institute, ARC, Egypt. Seeds with rate of 4 kg fed.-1 were planted under drip irrigation system. The experiment included 4 treatments in four replications. Plot area was 20 m2 containing 5 rows each of 8 m length and 50 cm between rows. All of the other agricultural practices were carried out as recommended for sunflower growing under the conditions of North Sinai as a semi-arid region. Plants thinned to single plant per hill after 15 days and distance between hills was 25 cm apart. This study was aimed to study the influence of different sowing dates (15th April, 15th May, 15th June and 15th July) on growth and yield components of sunflower (Sakha53) cultivar under North Sinai condition. Results indicated that 15th April was the favorable sowing date and increased each of plant height (cm), number of green leaves/plant, head diameter (cm), head weight (g), seed weight/plant (head), 100- seed weight (g), number of seeds/head and seed yield/fed. of sunflower (Sakha53) cultivar. | ||
