Study was conducted in Harran Plain-Şanlıurfa conditions according to complete randomized block design with tree replicates in 2010, 2011 and 2012. Samada-07 dent corn silage variety was used in the study. Sowing densities were 14285 plant/da (intra row space 10 cm), 10204 plant/da (intra row space 14 cm), 7937 plant/da (intra row space 18 cm), 6493 plant/da (intra row space 22 cm) and 5494 plant/da (intra row space 26 cm). Sowing densities were significant at silage yield, dry grass yield, plant height, stem diameter, leaf number and dry matter ratio (P≤0.01). The highest silage yield (6884 kg/da) and dry grass yield (2131 kg/da) were found at 14286 plant/da (10 cm intra row space) sowing density. But the highest dry matter ratio (%29.91) was obtained from 5494 plant/da (26 cm intra row space). Keywords : Corn, sowing density, silage yield, GAP, Harran Plain
