| Abstract : An RCBD 3X3factorial experiment with three replicates where conducted in a semi arid region in Bashika area located 12Km north–east of Nineveh province ,which depend on rainfall for irrigate, the study include the effect of three sowing dates the 1st of January,15th of January and 2nd of February on three varieties of wheat, these are Sham 6, Ebaa95, Ebaa99. Data recorder of plant height spike length, number of seeds per spike, number of spike per squared meter, 1000grain weight, yield kg/ha and the harvest index. Statistical analysis of the traits for the effects of varieties and dates of planting and their interaction showed significant effect of varieties at the 5% level for the number of spike/m2 while there were a significant effect of both spike length and the 1000 grain weight at the 1% level. While the dates of planting there were significance at the 5% level for the plant height, yield and wheat index. Whereas the interaction was significant and 1% level for the 1000 gram weight and yield Kg/ha. the Sham 6 variety was superior for the traits of 1000gram weight and harvest index, while Ibaa 99 showed superiority in plant height, length of spike, number of spikes/m2 and yield kg/ha. The 1st date of planning was the best in plant length, spike length ,number of seeds per spikes. While the 2nd date was superior in the 1000grm weight and the yield in kg/ha . While in case of interaction the variety Sham 6 with the 2nd date of planning showed superiority in both 1000gram weight and total yield. At the same time the variety Ibaa 99 with 1st date of planning where the best in the height of the plant, spike length and the number of spikes. | ||
