Comparison of GM hybrid maize MON 810 with hybrids selected
POSPÍCHAL, Miroslav
The aim of the thesis was to evaluate and to compare the rate of corn borer and the production capability of 4 hybrids of corn (Zeamays L.) of different earliness. For the comparison a variety test was layed out in the land of my father in Klimětice (Central Bohemia). Before the harvest a sampling for detection of dry matter content in the biomass has been made to determinate the date of harvest. The number of samplings depended on the attainment of required dry matter content in the biomass. By the harvest the yield and dry matter content of the biomass, yield and percentage of corn ears, dry matter yield and the starch yield were determined. In the experiments the differences in infestation of corn borer were determined. Further differences in observed parameters were found out, which were dependent on the different utility trends and earliness of the given hybrids. The result was the appreciation of the given hybrids and determining of their suitability for their growing in conditions of my fathers lands.
The production of biomass and dry matter at maize and sorghum for silage
TROJÁKOVÁ, Gabriela
The aim of this thesis was to evaluate and compare the production capacity of the two hybrids of maize (Zea mays L.) genotypes and selected sorghum (Sorghum Adams). For the evaluation of this experiment there was based a plot on the piece of land of South Bohemia University in České Budějovice. The samples were picked up before harvest to compare the evaluated high - yielding indicators. The number of samples depended on the desired dry matter content in biomass. During corn harvest the yield of biomass was determined, and yield and share of corncobs, dry matter content of biomass and corncobs, and yield of dry biomass. At the harvest of sorghum the yield of biomass was determined, the content of dry matter and yield of dry matter in biomass. Out of one-year experiment it was found out a slower increase of dry matter content in sorghum hybrids in comparison with the corn maize hybrids. Selected hybrids reached optimal values of solids dry matter content for the production of high quality silage.
