Výhody a nevýhody porostů ozimé pšenice založených jako směs odrůd

This thesis was aimed on the elaboration of literature review and a on the practical assessment of the field trial with a mixtures of varieties. The first part of the literature review was devoted to crop diversification in agriculture, which is closely related to mixtures of varieties. In the other part were characterized advantages of mixed varieties, such as better yield of mixed varieties in comparison with component varieties. We have also described some of the mechanisms for the creation of income (and mechanisms against pathogens). Another part was devoted to quality of mixed varieties. The last part was devoted to disadvantages resulting from the cultivation of mixed varieties. In the year 2013 it was founded field trial in Žabčice -- Nova obora, which was investigated in practical part. It was investigated effect of three binary mixtures. These mixtures were identified as : Elan + Golem, Viriato + Tobak Baletka and Annie. Each of pure component varieties were planted for checking and comparison. The main examined factors were yield, weight of thousand seeds, sedimentation index, wet gluten, gluten index, falling number, nitrogenous substances, weight and height of the plant. The best yield reached mixture Elan + Golem (average yield was 9.61 t / ha), it's yield reached the yield of the best variety Elan (9.92 t / ha). The mixture Tobak + Annie had higher average value of the falling number and nitrogenous substances than the pure varieties, average results this mixture reached in values of sedimentation index and wet gluten. In the total evaluation this mixture was recommended as the best one. The holder of the quality in this mixture was the Annie variety. This mixture has fulfilled requirements for baking quality and reached Czech elite level.
