Ourdays, the identification of friendly solutions in order to enhance physiological development of cereals is one of the main priorities of agriculture. This approach, also contributes to the promotion of the practices of the sustainable agriculture. A practice, which occupies more and more space is the use of endogenous type substances, as phytohormones, in order to increase cereals' physiological development, and nutritional traits. This is the context where the aim of our study is placed,

Two maize hybrids were studied, Turda Star, and Turda 200, respectively, and their elemental content was quantified by AAS, and raw data were processed with IBM SPSS Version 20. The results of our trial show the influence of GIBB A3 hormone upon the analyzed macro-(K, P, S, Cl, Mg, Ca), and microelemental (Fe, Mn, Zn) content of studied maize hybrids, mainly K, and P, which may also be considered as indicators of physiological status of the plant.
