Abstract
To study the effect of different levels of nitrogen fertilizer and foliar micronutrient boron element properties cropping of corn hybrid (SC704), an experiment was conducted in randomized complete block design with spilt-plot arrangement during 2011 growing season in agricultural research farm of Islamic Azad University, Varamin- Pishva, Iran. The main plots allotted to Nitrogen Fertilizer (N0= Lack of nitrogen fertilizer, N1= 50% recommended nitrogen fertilizer, N2= Use the recommended amount of fertilizer nitrogen, N3= nitrogen fertilizer by 50% over the recommended); sub plots allotted to Boron rates (B1= Sprayed with water, B2= foliar boron concentration of 500 g ha, B3= thousand liters of water and sprayed boron concentration of 800 grams per thousand liters of water per hectare). The results showed that, except during Tassel other traits measured under different nitrogen levels were significant. Increase nitrogen intake improves biological yield of corn. Average dry matter yield of 1.136 kg m N0 treatment to 1.345, 1.431 and 1.499 kilogram per square meter respectively for treatments N1, N2 and N3 increased. Also spray the element boron is also positive and significant effect on dry matter production of corn and its rate of 1.259 kg m B0 treatment to 1.393 and 1.406 kg per square meter, respectively, for the two treatments B1 and B2 increased. Nitrogen concentrations measured in the experiment were affected by different levels of nitrogen intake.
