Corn is the most important plant that is grown for silage both in our country and worldwide (Turgut, 2002). The concentrate feed requirement decreases by 33-50% in animals fed with corn silage (Sade and Soylu, 2008). Corn (Zea mays L.) is the most important silage plant which can satisfy the demand for both concentrate feed and fodder. Feed costs include 65% of animal production costs. The increase in the consumption of animal products can only be possible by producing these products in our own country in adequate amounts and at reasonable costs. Consumption of animal proteins should be increased to at least 50% for balanced nutrition (Tukel and Hatipoglu, 1997). Key words: Corn, drip irrigation, subsoil drip irrigation, subsoil capillary irrigation, plant density, silage quality parameters.Įven if hunger is not currently an issue in Turkey, we can still observe unbalanced nutrition dependent on cereals. When plant CP yield is taken into consideration, the 142 850 plant ha -1 density is more important. As a result of the research, high Flieg scores were obtained from each irrigation method and plant density. The highest fresh ear ratio values were obtained from subsoil capillary x 119 040 plant ha -1 and drip x 119 040 plant ha -1 interactions the highest plant and silage CP ratio values were obtained from subsoil capillary x 142 850 plant ha -1 and subsoil drip x 102 040 plant ha -1 interactions. While the irrigation method x plant density interactions were significant for silage CP ratio in the first year, they were significant on fresh ear ratio in the second year. The highest fresh ear ratio values were obtained with 102 040 and 119 040 plant ha -1 densities and the highest plant CP yield with 142 850 plant ha -1. Plant densities were significantly different on fresh ear ratio and plant crude protein (CP) yield in both years under study. Bailey) in 20 under ecological conditions in Eskipazar-Karabuk, Turkey. This study was conducted to determine the effects of different irrigation methods (drip, subsoil drip, and subsoil capillary) and different plant densities (102 040, 119 040, and 142 850 plant ha -1) on silage quality parameters of PR 31Y43 hybrid corn (Zea mays L. ( yield and quality of corn silage is related to genotype as well as factors such as climate, soil conditions, altitude, planting time, plant density, irrigation, and harvesting time. Bailey)ġKarabuk University Eskipazar Vocational School, Department of Plant and Animal Production, Karabuk, Turkey. Effects of different irrigation methods and plant densities on silage quality parameters of PR 31Y43 hybrid corn cultivar (Zea mays L.
