Abstract

To analyze the effects of NITROGEN fertilizer on YIELD, YIELD component, MORPHOLOGICAL CHARACTERISTICS and protein of MAIZE hybrids in climatic conditions of Dezful an experiment was conducted on the field of Islamic Azad University of Dezful Branch in arable year of 2009 in order to choose proper hybrid (s) compatible with the region, to remove harvest problem, to encounter hazards of the late season, and to use NITROGEN fertilizer optimally. This experiment was performed in the form of split plots in randomized complete block design in three replications. Treatments included three different levels of NITROGEN fertilizer (200, 240 and 280 kg/ha in the form of urea as main plots and five hybrid consisting of S.C.704 (control), S.C.700 and B.C.666 (foreign hybrid) and KLM and K47 (the group ripening earlier than the control) were in sub plots. The results obtained from this experiment showed that there was no significant statistical difference for grain YIELD at different levels of NITROGEN fertilizer. For different hybrids, significant statistical difference was observed such that the maximum and minimum amount of grain YIELDs with 10160 and 7447 kg/ha was associated with treatment KLM and K47 respectively. The results obtained for YIELD component indicated that the seed number per row, row number per ear and 1000 grain weight and also some MORPHOLOGICAL CHARACTERISTICS such as plant height, ear height from surface of the ground, ear diameter and era length no significant difference at various levels of NITROGEN fertilizer; however, a very significant difference was observed between hybrids. For the features of biological YIELD and harvest index there was a significant statistical difference between hybrids only. According to the results obtained from this study, the amount of 200 kg/ha NITROGEN was suggestible and the hybrid K47 made it possible to use environment (especially light and heat) and nutrition factors optimally.
