Abstract

Six field experiments were carried out at the experimental farm, faculty of agriculture, Zagazig university, Khattara region, Sharkia governorate, Egypt during two successive summer seasons of 2006 and 2007 to study the effect of planting density, nitrogen fertilization levels and sowing dates on yield attributes, yield and seed quality of two sunflower cultivars. The results indicated that delaying sowing date from April, 15th to May, 15th then to June, 15th significantly decreased plant height, head diameter, 100-seed weight, head seed density, weight of seeds / head, seed, oil and protein yields / fad. as well as seed oil content. The results also revealed the superiority of Sakha-53 cv. in upper mentioned characters as compared with Giza-102 cv. Wide spacing of 30 cm between hills (23,333 plants / fad.) appeared to produce the highest values of plant height, head diameter, 100-seed weight, head seed density, weight of seeds/head and seed oil content, while the dense planting of 35,000 plants / fad tended to produce higher seed, oil and protein yields / fad. Increasing nitrogen fertilization levels from 60 to 90 then to 120 kg N/fad. significantly increased plant height, head diameter, 100-seed weight, head seed density, weight of seeds/head, seed, oil and protein yields/fad. as well as seed oil content.
