Různé technologie hnojení při pěstování pšenice zimé

The aim of this bachelor thesis was to compare a fertilizing technology of the Yara Agri Czech republic, s.r.o. company with a classic winter wheat fertilizing technology (LAD) used in the Czech Republic. The issue was being solved in the economic year 2014/2015 by a small-scale field experiment at the Mendel University Brno experimental compound, at Žabčice Field Research Station and at Vatín Feed Research Station near the town of Žďár nad Sázavou to be exact. Three variants were included in the experiment: 1. Non-fertilized; 2. LAD fertilized; 3. Yara fertilizing technology. With the Yara variant, Sulphur-containing nitrogenous fertilizers were used, but not with the LAD variant. The influence of a variant on a nutritive state of the growth, as well as grain yield and its qualitative parameters were evaluated. A statistically conclusive influence of fertilizing on N-tester values, grain yield, ni-trogenous substances and sedimentation values of grain was observed at the Žabčice Field Research Station. The best results was achieved by the LAD variant, with its grain yield and N-tester values conclusively higher than both the non-fertilized variant and the Yara fertilizing technology variant. Regarding the N-substance content in grain and the sedimentation value, the fertilized variants were statistically inconclusive. At the Vatín Feed Research Station, the sedimentation value was statistically con-clusively higher with both the fertilized variants in comparison to the non-fertilized var-iant. The N-tester values were only statistically conclusively higher with the LAD vari-ant in comparison to both other variants. The results of grain yield and nitrogenous sub-stances content results were inconclusive and highly variable, with the control variant achieving better average results than the fertilized variant
