Abstract

Nitrogen is one of the most important elements needed in cereal crops especially CORN and its deficiency has been seen in agronomical fields of the world. To develop and improve of husbandry in the province and due to the need of development in cultivation of dent CORN alongside the forage CORN different experiments should be done in order to find out the agronomical needs of this kind of crop a field. Field experiment was conducted to evaluate the effect of NITROGEN FERTILIZER levels on GRAIN YIELD and YIELD COMPONENTS of CORN (Zea mays L.var.sc.704) at Chobar, GUILAN province using a randomized complete block design with 3 replications. Four levels of nitrogen (0, 67,138 and 207kgN/ha) were applied. GRAIN YIELD, YIELD COMPONENTS (grain number per ear, grain weight per ear and 1000 grain weight and other related traits (hectoliter weight, and ear length) were measured. The effects of nitrogen levels on all traits were significant. Application of 207kg/ha nitrogen resulted in highest GRAIN YIELD (10912.2 kg/ha), 1000 grain weight, grain weight, grain number per ear, hectolitre weight, ear length and grain weight per ear. Correlation coefficients showed that the ear length and the grains number per ear had positive and significant correlation with the GRAIN YIELD. Also the use of 207kgN/ha I increased the grain weight (227.1gr), 1000 grain weight(373.7gr) and hectoliter weight(72.84kg) and showed a positive and significant correlations with GRAIN YIELD.
