The yield formation and quality of winter wheat in low-input conditions

The aim of this thesis is to evaluate basic yield formation and food quality of grain in selected winter wheat varieties, depending on the intensity of cultivation. There was 5 varieties chosen for the experiment of which 3 was linear (Patras, Turandot and Rumor) and 2 varieties was hybrid (Hyfi and Hybery). Each variety was repeated three times during the experiment. The vegetation was assessed in two variations - the checking one and the one fertilized by the nitrogen. This experiment was conducted in growing season 2017/2018 on the field of Faculty of Agriculture of University of South Bohemia. The withdrawal of the vegetal material for the purpose of the following sample analysis was done right before the harvesting. The yield formation and the health condition of the vegetation was assessed in the fieldwork. The determination of qualitative parameters was made with the help of the apparatus in the laboratory of the faculty. Then, the results was marked in tables and graphics. Finally, the statistical evaluation of the obtained data. An average yield of all assessed varieties of the winter wheat was 8,52 t.ha-1 at the checking variation. On the contrary, at the nitrogen fertilized one the average yield was 8,94 t.ha-1. The evaluated varieties in the growing season 2017/2018 had the baking quality A and B. Regarding the qualitative parameters, there was found lower values of volume quantity than those that are stated in the norm for the food wheat (at least 76,0 kg.hl-1). The highest values were found at the variety Turandot fertilized by nitrogen (77,8 kg.hl-1), which met the requirements of the ČSN 4611 00-2
