This study was conducted in the years 1991 and 1992 with 25 Egyptian species in the conditions of Erzurum. The output period of the varieties in the years 1991 and 1992 is 21.9 and 15.1 days respectively,the output period of the spice is 87.4 and 89.0 days, the output period of the spice is 92.5 and 92.8 days, the maturation period for the silage is 117.0 and 112.2 days, the number of leaves per wheat is 12.0 and 12.1 pieces, the number of spice per plant is 1.2 and 1.1 pieces, the length of the plant is 197.8 and 191.2 cm, the yield rate is 6811.1 and 6320.9 kg/day, the yield rate is 24.3 and 23.3, the yield rate is 1652.7 and 1460.7 kg, the yield rate is 5.25% and 5.80, the yield rate is 85.2 and 84.7 kg. According to the results of this research, even in the silagic eggs cultivation in Erzurum Ovas, the late mature varieties are dangerous and should be focused on early varieties, the early and relatively high-performance varieties of lnra 260 and lnra 380 and Tortum-1 are hopeful varieties that can be used for silagic purposes in Erzurum ecology. DETERMINATION OF CORN CULTIVARS FOR SILAGE PRODUCTION IN ERZURUM SUMMARY: This study was conducted using 25 corn cultivars in Erzurum in 1991 and 1992As an average of cultivars, median ernergence time vvai- 21.9 and 15 1 days, days lo 50% tasseling were 87.4 and 89.0, days to 50% silking were 92.5 and 92.8, days to maturity for silage were 117.0 and 112.2, leaf number per plant was 12.0 and 12.1, ear number per plan was 1.2 and 1. 1, plan height was 197.8 and 191.2 cm, green material yield was 6811.1 and 6320.9 kglda, dry rnaiıer comenl was 24.3 and 23.3%, dry material yield was 1652.7 and 1460.7 kglda, crude protein conieni >vas 5.25 and 5.80% and crude protein yield was 852 and 84.7 kglda respectively in 1991 and 1992 . This study suggested thal late maturing corn cultivars were risky evenfor silage produc-tion in Erzurum and, therefore, early genotypes must be considered. Early and high yielding cultivars of lnra 260, lnra 380 and Tortum-1 were promising for silage production.
