Abstract:

For effect of nitrogen fertilizer on yield component of maize an experiment was carried out at Research Station of Islamic azad university of Miandoab in 2012. The experiment was conducted as factorial based on completely randomized block design with four replications. Cultivars included hybrids of SC301 and SC320 (early hybrids of corn). Treatments were nitrogen levels fertilizer (100, 150, 200 and 250 kg N ha-1). Plant density was 90 plants ha-1. In this study indicated that number of ear (ears m-2) meter hybrid of SC320 was significantly higher than SC301 but number of grains (grains ear-1) and 1000-grain weight (g) in hybrid of SC320 was significantly lower than SC301. It was found that increasing nitrogen fertilizer levels significantly increased the number of ears per unit area and one thousand grain weight reduced one number of grains per ear.
