WHEAT YIELD RESULTS UNDER THE INFLUENCE OF N, P, K FERTILIZATION AND CLIMATIC CONDITION

The aim of the work was to carry out a study on the influence of climatic conditions and fertilization with chemical fertilizers on wheat production in the specific conditions of Didactical Farm (SDE) of the University of Life Sciences "King Mihai I" from Timisoara (ULST). A Fundamental contribution to the increase of the yield per unit area is made by the level of N, P. K fertilization and optimal soil and climatic conditions for exploiting the productive potential of the cultivated variety. The high ecological plasticity of wheat and its constant productions 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 this paper is to highlight the yield results of Ciprian wheat variety, obtained in the soil and climatic conditions of SDE during 2019-2020, under the influence of nitrogen, phosphorus and potassium fertilization in order to determine the growers to choose an optimal wheat fertilization option. Wheat yield obtained was determined by nitrogen fertilizer application from the control variant as follows: N30- 485gk/ha, N60-584 kg/ha, N90-605 kg/ha, at all four rates the differences are statistically assured as highly significant.
