WINTER WHEAT YIELD AND QUALITY DEPENDING ON CHEMICAL FERTILIZATION, DIFFERENT TREATMENTS AND TILLAGE SYSTEMS

Winter wheat is one of the most important crop in the world of particular economic importance, bread made from wheat flour being the essential food, also ensuring about 20% total calories consumed. Identifying a technology that ensures a superior quality, but also a high and stable production of the wheat crop by choosing: the right tillage system, the optimal level of fertilization and the treatment to combat diseases and pests is one of the priorities of agricultural research. In order to evaluate the influence of chemical fertilization, seed treatment and tillage system on winter wheat yield and quality, a field experiment was conducted at Agricultural Research and Development Station Turda (ARDS Turda), in 2020-2021. The Andrada winter wheat variety was used for the experiment. The experimental factors were: soil tillage system with four graduations, seed and foliar treatment with three graduations and chemical fertilization with three graduations. Even if high yield was obtained when conventional system was adopted, good winter wheat yield was observed in minimum tillage or no-tillage system when high doses of fertilization were experimented.
