Porovnání výnosu a kvality zrna u vybraných odrůd pšenice ozimé v konvenčním a ekologickém způsobu pěstování
Voňková, Terezie
This bachelor thesis aimed to compare the yield and grain quality of eight varieties of winter wheat grown using conventional and organic cultivation practice. The experiment was conducted at the Field Experimental Station in Žabčice, and the varieties included Genius, Butterfly, LG Orlice, Illusion, Pirueta, Mercedes, LG Absalon, and RGT Telemark. All these varieties were registered for conventional farming and are tested for suitability for organic farming. Two experiments were established in the same field with the same fore crop of alfalfa (Medicago sativa). The organic experiment was grown in accordance with eco-farming regulations. The basic parameters for baking quality were determined at the Breeding Station RAGT Czech s.r.o. in Branišovice. This thesis compares results of yield, thousand seed weight, protein concentration in dry matter, Zeleny sediment test, falling number amount and wet gluten content. Yield of most of varieties was higher in the conventional experiment than in the organic experiment. The average yield of the conventional experiment was 0,56 t·ha-1 higher than the average yield of the organic experiment. The difference of thousand seed weight and all of tested parametres of quality ended same as in yield comparison. The conventional experiment was 0,5 g higher in thousand seed weight than the organic experiment. In Zeleny sediment test was results of conventional experiment 2,5 ml higher than in the organic experiment. The conventional experiment had 0,6 % higher protein concentration in dry matter. The conventional experiment had 26 s higher falling number than the organic experiment. The wet gluten content was 0,7 % higher in conventional experiment than in organic experiment. Overall the conventional experiment had higher yield and better quality in all aspects than the organic experiment.
