GROWTH AND YIELD OF SOME PROMISING WHEAT GENOTYPES AS AFFECTED BY SEEDING RATE AND NITROGEN FERTILIZATION
Abstract: Tow field experiments were carried out at Sids Agricultural Research Station, Agricultural Research Center during 1996 / 97 and 1997/98 growing seasons to evaluate the two long spike wheat varieties Sids 8 and Sids 10 versus the commercial cultivar Sids 1 .
The three bread wheat genotypes were supplied with 4 N levels (75, 100, 125 and 150 kg / fad.) and were seeded at 3 seeding rates ( 300,350 and 400 seeds / m ² in the first season and 200, 400 and 600 seeds / m ² in the second season. Results showed that.:
• No significant differences were detected in biological yield , grain yield / fad. And harvest index among the three genotypes. However sids 8 outyielded sids 1, and sids 10 in grain yield by 4.8 and 11.9% in the first season, respectively, corresponding to 6.8 and 5.4 % in the second season. The present t results did not show any clear superiority of the long spike genotypes over the commercial cultivar sids 1. the main defect of these genotypes is the few number of spikes / m ² due to their limited tillering capacity.
• Biological yield / fad. significantly increased by increasing N level in 1996 / 97 season , whereas grain yield / fad was not affected.
• LAD from anthesis to ripening increased with increasing seeding rate . On the other hand FLA insignificantly reduced due to increasing seeding rate.
