Abstract
A field experiment was performed during the autumn season of 2011 year in the (Abi Garaq) 10km west Hilla city. To study the effects of two cultivars ( Engath ، Kaffer) and cutting stages ( booting stage , half bloom ,soft dough stage) on chemical characteristics . the experiment was Applied by using split –plots according to (R.C.B.D) with three replicates. Cultivars were assigned as a main-plots. and cutting stages as sub- plots. The results indicated that using kaffer cultivar significantly increased the percentage of dry matter and protein percent while using (Engath) cultivar significantly increased the total ash percent .the cutting stages was significantly different in all the studied charecteristics .soft dough stage was given higher percent of dry matter yield and protein percent and crude fiber percent , While booting stage was given higher protin percent and total ash percent .Soft dough stage was also given higher dry matter percent was ( 13.17) ton.ha. the results indicated significant interactions between cultivars and cutting stages in dry matter percnt and total ash percent .
