摘要：This study was performed in order to evaluate the yield and grain quality of four maize hybrids: Pioneer 31G98, Carella, Famoso and NK-Arma, among different plant densities of 89286, 79365, 71429, 64935 and 59524 plants ha-1, at Aydin-Turkey in 2010 and 2011 growing seasons. The significant hybrid x plant density interactions estimated for protein and oil content and fatty acid composition such as palmitic, oleic, linoleic and linolenic. There was a quadratic response of grain yield to plant density, and the most profitable yield of all hybrids was at 71429 plant ha-1. The significant effects of planting arrangements and varieties on quality of maize revealed that different plant density and variety should be suggested for grain quality parameters.
