Results of the two—year experiment at Nit-Ghamr, Dakah— lia, showed that N had a significant effect on major yield components. The highest head diameter. weight of seed per head, weight of seeds per• plant were obtaln•d with 40 kg/fad. in both seasons. The 100-seed weight character showed the highest increase with 20 kg/fad. shelling per centage was not affected by rat, of N. The highest seed yield/fad. was favored in both seasons with 40 kg N/fad. However, straw and biological yields were the highest with 20 and 40 kg N/fad. in the first and the second season, respectively. N affected oil percent adversely but had no effect on oil acidity or saponification value. Protein con tent of seeds was increased by increasing up to 40 kg/fad. None of the characters included was affected by the applica— tion treatment. Rate X application treatments was not sig nificant for all traits and thus considered
