This bachelor thesis is focused on comparing selected varieties of winter wheat based on efficiency of their pesticide’s treatment cost in the Czech Republic. 13 varieties were chosen from the List of recommended varieties (SDO) between years 2015 and 2019. Data for calculations were provided by the Central Institute for Supervising and Testing in Agriculture (ÚKZUZ). Conclusion was focused mostly on comparison of yield ability of varieties in treated and untreated variants of testing in small plot field experiments and an increase in the contribution to the payment (increase in the CP = difference between increase in sales and increase in variable costs) in response to the intensification on the treated variant. The highest CP was achieved by varieties Elly and Bohemia, which showed lower resistance against illnesses, which is why they reacted well to intensification by pesticides and nitrogen fertilizers. On the other hand, profitable varieties with higher resistance against illnesses (Gordian and Dagmar), did not show increase in the CP on the treated variant, however they reached above average sales (Kč/ha) in all testing areas. Varieties of this kind van be used in so-called ecological agriculture, allowing high level of production and yield to be maintained while reducing the amount of used agrochemicals. |
