In order to comparisation of yield, yield components and morphologic characteristics of maize hybrids in second cropping in Khoy region, an experiment was carried out in summer 2004 in research farm of Islamic Azad University, Khoy branch. In this experiment, seven hybrids of maize including very early ripening hybrid K.S.0 108, early ripening hybrids K.S.0 301, K.S.0 303, hybrid K.S.0 404, semi delay ripening hybrids K.S.0 600, K.S.0 604 and K.S.0 647 comparised by randomized complete block design in four replications. Tenth of July was determined as Planting date of all experimental varieties. Maximum dry matter, fresh fodder, leaf dry weight, stem dry weight, stem height and stem diameter obtained in 647 three way cross hybrid and highest leaf area index obtained in K.S.0 404. uppest ear/shoot ratio obtained in K.S.0 303 and the highest ear dry weight obtained in 600 hybrid variety. Result of this study showed that 647 T.W.0 hybrid corn is the best silage corn hybrid for secondary cropping in khoy region.
