Abstract
The present investigation was carried out during 2002/2003 and 2003/2004 growing seasons at Nubaria Aqriculture Research Station. A split split plot design was used. The objectives of this investigation was aimed to study the effect of irrigation treatments (two, three and five irrigations), the nitrogen fertilizer rates (72, 144 'and 216 Kg N I hal 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 t ha and its components. There is insignificant differences between two irrigations treatment or three irrigations treatment on number of sptkes/rn" and number of grains f spike, grain yield tha which reduced by 17.57 and 4.82 % compared with full irrigation treatment.
2-lncreasing nitrogen fertilizer rates from 72, 144 to 216 Kg N/ha significantly increased number of splkes/rn'', number of grains t spike, straw, grain and biological yields tha and harvest index.
3-Results indicated that Bhrikuti, CM 85836 and ICW 92 genotypes were recorded highest grain yield fha, number of grains 1 spike, and 1000 grain weight without significant differences between them.
In general, it could be recommended that utilization of five irrigations and addation of 216 Kg N fha could give the highest wheat yield under newly reclaimed land conditions.
