Abstract :

This research was conducted to determine the effects of different cultivars (PR 31Y43, OSSK-644 and Lacasta) and fertilizer treatments (organic, inorganic, ½ organic + ½ inorganic) on some corn silage quality parameters in the years 2011 and 2012 under the ecological conditions of Eskipazar-Karabuk. The fertilizer treatments were statistically significant on silage dry matter and dry stem ratio values in the second research year and highest values were obtained from inorganic and ½ organic + ½ inorganic fertilizer treatments. While the highest fresh ear ratio values were obtained from Lacasta cultivar in both research years, highest dry leaf ratio values were obtained from PR 31Y43 and Lacasta cultivars in the second research year. High flieg scores obtained from each of the fertilization treatments and corn cultivars in the first and second research year. When we consider the negative effects of inorganic fertilizers on human and environmental health, organic fertilizer treatments come into prominence. Each of the corn cultivars would be preferable due to high flieg scores.
