Abstract :Nitrogen insert ignore into journalissuearticles values(N); is one of the most important and complex nutrients for the crop plants especially for grain yield and quality. Field trials were carried out in 2007-08 and 2008-09 growing years to investigate response of six oat cultivars insert ignore into journalissuearticles values(Seydisehir, Apak, Yesilkoy-330, Amasya, Checota and Yesilkoy-1779); to three N rates insert ignore into journalissuearticles values(0, 10 and 20 kg da-1); for agronomical traits. In the research the traits such as panicle number per m-2 insert ignore into journalissuearticles values(PN m-2);, plant height insert ignore into journalissuearticles values(PH);, grain number per panicle insert ignore into journalissuearticles values(GNP);, grain weight per panicle insert ignore into journalissuearticles values(GWP);, 1000-grain weight insert ignore into journalissuearticles values(1000-GW);, grain yield insert ignore into journalissuearticles values(GY);, biomass insert ignore into journalissuearticles values(BY); and harvest index insert ignore into journalissuearticles values(HI); were investigated. Results indicate that agronomical traits significantly differed for the years, cultivars and N rates, except PH for cultivars. Among the cultivars, Checota had the highest GWP, 1000-GW and GY insert ignore into journalissuearticles values(3.12 g, 38.5 g and 259.6 kg da-1 respectively);, while Seydisehir had the highest PN m-2 and BY insert ignore into journalissuearticles values(543 PN m-2 and 1666 kg da-1 respectively);. Investigated traits were gradually increased with increasing of nitrogen rates. Checota cultivar had the highest GY, while Seydisehir cv. had the highest BY at 20 kg da-1 N rate
