e ( rain fall only; supplemental irrigation with rain fall) on yield, yield components, and grain physiochemical properties of six bread wheat varieties (Tamoz/2, Ez/66, Abu-ghraeb/3, Telafar/3 Cham/6 and Iba'a/99) Afield experiment was carried out at two sites using split plot in RCBD design.

The results showed the supplementary irrigation did not affect yield components and physiochemical properties of grain at both location except grain yield (gm/m2) in both location, wet gluten in Faidah and test weight in Mosul.
