The main purpose of the research undertaken to develop this work was the impact of chemical fertilization on maize yield in the experimental field of SDE Timisoara. Fertilizers make their best contribution to the enhancement only if it falls within a hierarchical system of technological measures good and the doses used are related to crop plants, soil, climate and culture technology. The fertilization system influenced the maize harvest, leading to production of 9123 kg of maize / ha. In recent years, the amount of fertilizer used has remained relatively constant while average yields have steadily increased. Because of the complex nature of soil and weather variability, farmers face significant challenges in optimizing the amount of nitrogen to apply to each field, year and area within a field. This results in under-application of nitrogen in some years and fields, with resulting yield losses and over application of nitrogen in other years and field areas resulting in inefficient use of nitrogen resources
