The main objective of the research is to determine how the localized application at seeding of different type of chemical fertilizers, influences the raw protein, amino acid, hectoliter weight and fat composition of the maize grain. Corn constitutes an important source of carbohydrates, protein, vitamin and mineral. The research takes place in experimental field from U.S.A.M.V.B. "King Michael I of Romania" in Timisoara Didactic Station from Timisoara and after that in the research lab of Soil Science Department from Agricultural Faculty. The experiments are stationary type, with wheat – maize – sun flower rotation. Each plot is sub-dived in four repetitions, linear, with size of 10 x 3 m (30 m2). The hybrid used for this experiment is MAS 44 A. The fertilizers used are: Microstar 10.40.0 + 11 SO3 + 2 Zn micro granulated fertilizers, 15.15.15 complex mineral fertilizers, N 28 liquid foliar fertilizers. To obtain changes as corn, chemical fertilizers were used rationally. Crop quality is appreciated not only by morphological and technological but by the content of biochemical compounds (carbohydrates, proteins, essential amino acids, minerals, vitamins, and fats).
