| Abstract |
The present investigation was carried out during 2002/2003 and 2003/2004 growing seasons at Nubaria Agriculture Research Station. A split split plot design of irrigation treatments (two, three and five irrigations), the nitrogen fertilizer rates (72, 144 and 216 kg N/ha) on productivity of some bread wheat genotypes. The main results could be summarized as follows:
1 - Results showed that full irrigation treatments significantly maximized grain yield/ha and its components. There is insignificant differences between two irrigations treatment or three irrigations treatment on number of spikes/m2 and number of grains/spike, grain yield/ha which reduced by 17.57 and 4.82% compared with full irrigation treatment.
2 - Increasing nitrogen fertilizer rates from 72, 144 to 216 kg N/ha significantly increased number of spikes/m2, number of grains/spike, straw, grain and biological yields/ha and harvest index.
3 - Results indicated that Bhrikuti, CM 85836 and ICW 92 genotypes were recorded highest grain yield/ha, number of grains/spike, and 1000-grain weight without significant differences between them.
In general, it could be recommended that utilization of five irrigations and addition of 216 kg N/ha could give the highest wheat yield under newly reclaimed land conditions.
