Determination of Crude Protein Yield and Some Quality Traits in Different Silage Corn Varieties

The study was conducted to determine crude protein yield and some quality traits of different silage corn varieties (samada-07, arifiye, sakarya, ada-9510, ada-9516, ada-523, aga, kerbanis, keravnos, kolessous, simpatico, kilowatt, kalideas, larigal, sy-antex, sy-inove, sy-gladius and dragma) in the ecological conditions of bilecik during the two years (2019-2020). the experiments were arranged in randomized blocks design with three replications. in the silage corn varieties harvested at dough stage and, crude protein content, crude protein yield, acid detergent fiber (adf), neutral detergent fiber (ndf), potassium (k), phosphorus (p), calcium (ca) and magnesium (mg) content were investigated. according to the results of two years; crude protein content ranged between 6.58-9.84%. the highest crude protein yield was determined samada-07 (353.64 kg/da), sakarya (287.80 kg/da), ada-9510 (288.12 kg/da), ada-9516 (340.45 kg/da), aga (294.41 kg/da), sy-inove (285.36 kg/da) and sy-gladius (315.44 kg/da), while the lowest was simpatico (207.35 kg/da). the adf ve ndf ratios ranged between 29.28-42.69% and 46.65-67.23%, respectively. the mineral content of corn varieties for silage was at a level to meet the needs of the livestock. as a result; sakarya, ada-9510, ada-9516, sy-inove, and sy-gladius varieties have exhibited superior performance in terms of protein yield and quality traits.
