The diploma thesis deals with the cultivation of grain maize in the system of soil protection utlilizing underseeding and cover plants. It investigates the effect of underseeding of selected plant species on crop of corn grain. It assesses the suitability and potential of each species for their cultivation in the "subsoil" in view of limiting the production process of the main crop and at the same time soil protection function. In the 2018 experiment, 8 variants of the cover plants were included: soy, milk thistle, facelia, clover, ryegrass, pea-oat-pea, oat-pea, mixture of KeepSoil Corn. The following signs were observed on maize: total plant height, weight of one roll, length of the roll, number of grains per cross-section, harvest moisture, grain weight from 20 rolls. The cover plants were monitored for: soil cover and production of above-ground phytomass per unit area. The statistical evaluation shows that the crop of maize grain was affected by: milk thistle, pea-oat-pea, facelia, clover, ryegrass, pea-oat. Soil cover of at least 50% has been achieved by: milk thistle, facelias, ryegrass, mixture of KeepSoil Corn. From the results of the experiment it is possible to unambiguously recommend a milk thistle, facelium, ryegrass and commercial mixture of KeepSoil Corn as a grain maize cover crops. The experiment was carried out in extremely dry year 2018, which has also affected the results. |
