This study was conducted in the winter season of 2012-2013 at AL- Hemidat / thaljah village (20 km) west of Mosul and in the fields of the Faculty of Agriculture and Forestry - University of Mosul.

The study was carried at each of the two Location to study the effect of supplementary irrigation on growth character, forage and grain yield of five varieties namely (ICARDA Tall , Possum , Mitika, Kangaroo and ICARDA Short).

The experiment was carried out according to split plot desing with three replicates.

showed :ICARDA Tall varietiy surpassed on all studied varieties in fresh and dry forage yield and gave at Mosul Location, 26.3 and 5.5 ton/ha in mosul Location and 17.7and 3.64 ton/ha in Thalija Location respectively, while Kangaroo varietiy surpassed on the varieties of ICARDA Tall , Possum , Mitika , and ICARDA Short in grain yield and gave in 2.1 ton/ha Mosul Location and 2.88 ton/ha in Thalija Location.

All the growth character , forage and grain yield not affected significantly by supplemental irrigation except the number of tillers / m2 at Thaljah Location and fresh yield at the Mosul Location connector and the Panicles/m2 at both Locathions A higher grain yield achieve from the interaction between varietiy K with rain at Mosul Location 2.13 ton/ha in the thaljah 2.4 ton/ha of interaction varietiy K also with rain gave the interaction between varietiy T and supplementary irrigation highest fresh and dry forage yield at Mosul Location, 27.5 and 5.7 ton/ha at thaljah Location 17.7 and 3.7 ton/ha and , respectively
