¹ Batı Akdeniz Tarımsal Araştırma Enstitüsü, Antalya DOI : 10.21566/tarbitderg.282818 - This research was conducted West Mediterranean Agricultural Research Institute in 2012 in Aksu Agronomy Department. BATEM 7252 as the study material (in SI), BATEM 7255 (DAWN) and BATEM 5455 (Burak) silage corn varieties are used. Dekar silage yield, the silage quality criteria in samples taken from the silage ADF (acid insoluble detergent fiber), ADL (acid detergent insoluble lignin) and NDF (neutral insoluble detergent fiber), crude protein, crude fat, crude fiber, pH, Flieger points, ash silage, it was examined in the silage dry matter and soil characteristics. Burak control plots, SIDE, respectively, the average yield varieties John DAWN kind 5281kg / ha, Side at 5193 kg / 5226 and the dawn sort kg/ha, respectively. 28 kg/ha of nitrogen application on the yield, respectively, 8348, 8114 and 8583kg/ it is determined. The highest nitrogen application (35 kg / N) in yield reductions were seen. N. in silage quality value (nitrogen), depending on the amount of ADF, ADL, NDF, pH, Flieger points and decreased ash content in the silage crude protein silage formed increases the maximum point in parallel to increase the amount of nitrogen was observed to affect the fat content of nitrogen. Of dry matter content in silage showed a decrease depending on the amount of nitrogen. To increase the quality of silage made in the analysis above and the animals were found to reduce the discarded items by facilitating the digestion. Keywords : Zea mays, silage, nitrogen, quality
