Nutrients are essential for plant growth and soil that was found with high pH levels in alkaline character regions negatively affected the uptake of micronutrients (Zn, B, Mn, Cu, Co, Mg, Se, and Fe) with the exclusion of molybdenum. Current practices in attempts to solve this problem is to add nutrient fertilizers and natural hormone combinations via foliar. In this study nutrients and natural hormone combinations that could not be taken by roots were applied to the leaf and the effects on corn analyses. The experiment carried out in 2010 and 2011 was under in the field conditions in Aydin. Plant materials used in this experiment were: NK-Arma, 31G98, Kermes and 31D24 hybrid corn varieties which is cultivated commercially in Turkey. The fertilizer solutions included: a solution (1) containing auxin and zinc (Zn) foliar and a solution (2) containing boron (B) fertilizers were used. At the end of the final study it was determined that the yield of 168.8-260.0 g in cob had been obtained. Protein measurement revealed between 826-1505 kg.ha-1, fatty yield was determined between 359-574 kg.ha-1 in the total yield. We observed that solution 1 (auxin and Zn) and solution 2 (B) applications positively affected both the corn yield and the quality in this study. Additionally it was found that foliar applications prolonged corn’s vegetative period and increased GDD average values of the vegetative period with Auxin, Zn and B applications. The highest cob yield, protein yield and fatty yield values were found in 31D24 and this genotype stood out from all other genotypes in the research.
