Abstract

Two field experiments were conducted in two successive season at two sites El-Emam Malek Village and NRC Farm (according to the cultivation periods), Nubaria, Behaira Governorate to study the effect of two types of sprinkler irrigation system and three water amount on Coefficient of variation (CV) and water productivity (WP) of wheat crop (Triticumaestivum L. cv. Gemmaiza 9, Varity).  The results could be summarized as following: Coefficient of variation (CV) had been practical evaluated in the two experimental fields for two irrigation systems types under studying and resulted were 16.7 and 32.5 under using Permanent and Simi portable sprinkler irrigation systems, respectively. The effects of the sprinkler irrigation type on all studied of quality parameters were significant at the 5% level except seed index. Decreasing the irrigation water from I 100 to I 75 or I 50 had positive effects on % net flour, % of grain protein, % of fat and % of total sugar. Differences in most parameters among treatments were significant at the 5% level. Moving the lateral lines in SPS system after irrigation each 4 days in a wet soil caused soil compaction, poor aeration and root growth impedance. The better production of in grain wheat quality under experiment conditions was in the second season 2012/2013. The permanent sprinkler system gave the highest grain wheat quality.  

Keywords: Sprinkler, Semi-portable, Permanent, CV, Wheat, quality.
