The experiment was conducted in 4 replicates according to a split-plot design. The difference between sowing densities and nitrogen doses plant height, ear height and gren yield significant. According to the results, when sowing densities an d nitrogen doses the highest plant height, ear height and green yield was obtained 70x10 (14 bitki/m²) sowind densitie and dose of nitrogen N₂₅.
