The aim of the work is to carry out a study on the influence of climatic conditions and fertilization with chemical fertilizers on wheat production, in the specific conditions of Pecica, county of Arad. A fundamental contribution to the increase in production per unit area is made by the level of N, P and K fertilisation and optimal soil and climatic conditions for exploiting the productive potential of the cultivated variety. The high ecological plasticity of wheat and its constant production means that farmers are still very interested in this crop. Growers are also interested in the crop with the highest yield per unit area. The aim of the paper is to highlight the production results of Ciprian wheat variety obtained in the soil and climatic conditions of the Pecica-Arad of 2019-2020, under the influence of nitrogen, phosphorus and potassium fertilization in order to determine the growers to choose the optimal wheat fertilization option. Wheat yield obtained was determined by nitrogen fertilizer application by difference from the control variant as follows: N30-485kg/ha, N60-584kg/ha, N90605kg/ha and N120kg/ha, at all four rates the differences are statistically assured as highly significant. With reference to the influence of climatic factors the greatest influence is had by the variable precipitation (Pp), followed by temperature, and N fertilizer has the greatest influence, followed by P-dose, K-dose.
