Abstract

A field experiment was carried out during a successive growing season of 2007 and 2008 at Abu-Ghriab, Experimental Research Station,State Board for Agricultural Research, Baghdad , Iraq. Using a Randomize Complete Block Design , to evaluate the performance of six forage hybrids , belong to different forage field crops ( Sorghum , Sudan grass and Millet ).
The results indicated the exceeding two hybrids Superdan-2 (sudan grass) and Sweet jumbo(sorghum) superiority in total green yield ( 66.85 , 66.1 , 66.48 , 66.51 , 65.81and 66.16 t/ha . ) ، total dry matter (9.84, 9.64 , 9.74 , 9.55 ,10.02 and 9.79 t/ha.) and total dry leaf yield ( 5.25, 5.15, 5.2 , 5.11 , 5.41 , and 5.26 t/ha), Nutrifeed (millet) gave the highest dry leaf/stem ratio: 54.53% , 54.29% then sweet jumbo ( 53.7% , 53.56%) and Superdan 2 (53.42% , 53.28%) for the first and second cuts for the two seasons 2008 and 2009 respectively. Nutrifeed , Superdan-2 and Sweet were resistance to loading and leaf rust and have the highest protein percentage ( 16-22% , 12-18% , and 12-18 %) respectively. And could be used for making high quality hay and silage.
