Four cultivars of soft wheat (Abu Ghraib, IPA 99, Sham 6 and Al Ezz) were planted in sandy loam soil in one of the countryside of Ramadi in the two agricultural seasons 2012-2013 and 2013-2014. The aim of the study was to know the growth and production of these cultivars under the influence of levels of DAP fertilizer (0, 100, 200 and 300) kg.h −1 . The cultivars (main plot) and levels of fertilizer (Sub-plots). These factors (4×4) were input with design in RCBD at three replicates. The seeds were sown at a rate of 120 kg.h −1 on the first half of December. The results showed that IPA 99 had the highest mean spike length by 12.8 and 12.4 cm and while the highest number of grains were 90.0 and 83.7 for each spike, which resulted in high grain yield 6.9 and 4.2 t.h −1 which was non significantly different from the product of Abu Ghraib and Sham 6, which gave high rates of grain in both seasons. Sham 6 has the highest number of spike per square meter 484.8 and 469.3 spikes in both seasons. The addition of DAP fertilizer didn’t affect the length of spike, number of grains per spike and the weight of 1000 grains, while the effect of adding it significantly in the number of spikes per square meter and the grain yield. Adding the level of fertilizer 200 and 300 kg.h −1 gave the highest rate of the number of spikes that reached (432.6, 436.7) in the first season and (437.5, 438.0) spike in the second season, as well as the highest equivalent of the grain yield of 6.7 and 4.1 t.h −1 respectively. In conclusion cultivars varied in their productivity and showed an obvious response to the addition of DAP fertilizer, especially the addition of 200 kg.h −1 , which is capable of processing the necessary nitrogen and phosphorus for the growth and production of wheat.
