The study was conducted to determine hay yield and some quality characteristics of 18 silage maize varieties in the ecological conditions of Bilecik during the 2019 and 2020 years. The experiments were arranged in randomized blocks design with three replications. In the silage corn varieties harvested at dough stage and, plant height, stem diameter, number of leaf, number of ear, first ear height, ear weight and hay yield were investigated. According to the results of two years; plant height, stem diameter, number of leaf, number of ear, first ear height, ear weight ranged between 2.98-3.78 m, 1.75-2.76 m, 11.70-16.53, 1.41-2.44, 0.99-1.52 m and 337.89-534.60 g respectively. The highest dry matter yield was determined in Samada-07 (4262,57 kg/da), Arifiye (4086,03 kg/da), ADA-9516 (3634,06 kg/da) ve AGA (3644,14 kg/da), while the lowest was in Simpatico (2503,62 kg/da). As a result, it was determined that FAO groups are important for variety selection in Bilecik ecological conditions, and latest varieties are better than the median and earliest varieties. In this respect, Samada-07, Arifiye, ADA-9516 and AGA varieties performed better than other corn varieties in terms of the morphological characteristics and hay yield.
