Evaluation of yield and qualitative parameters in hybrid winter rye

The main part of the thesis is evaluation of yield and qualitative parameters of hybrid winter rye. A small plot experiment was made at the Faculty of Agriculture of the University of South Bohemia in České Budějovice (380 m). The trial took place in two years: 2016/2017 and 2017/2018. The effect of sowing (early and late), seed quantity (standard - 2 MKS / ha and reduced - 1 MKS / ha), variety and year were evaluated in three varieties of hybrid rye (Cossani, Performer, Santini). To achieve the most accurate results, all 12 variants were sown in 4 replicates. From the qualitative parameters were determined: Falling number, volume weight, content of N substances. Concerning the yield, use of a standard seed rate (2 MKS / ha) was more stable, with an average yield increase of 0.64 t / ha. The most profitable was the Performer variety, which stood out with a consistently high falling number
