The influence of selection of maize hybrid on forage quality

The aim is to assess the impact of choosing hybrid for digestibility of neutral detergent fiber in forage maize in relation to other quality parameters. Recommendations on hybrids based on testing can be economically advantageous for growers. At the beginning of the experiment hypothesis was stated: Selection of maize hybrid for the habitat significantly affects reached digestibility neutral detergent fiber when harvested for silage. Nine different maize hybrids in triplicate were enrolled in the experiment (Dynamite, NK Octet, Rubben, DKC 3507, 3795 DKC, DKC 4014, Susann, 30,311 LG and LG 32.64) for cultivation on an experimental plot in Prague Uhříněves. The evaluated characteristics were, inter alia, revenue and portion of buds. To evaluate the chemical analysis of samples was collected chop of the whole plant from the middle rows of experimental plots. Following parameters were evaluated: content of crude protein, content of neutral detergent fiber, content of digestible neutral detergent fiber, digestible organic matter, starch and solids content. Among the hybrids significant differences were observed in parameters: revenue, portion of buds, protein content, content of neutral detergent, content of digestible neutral detergent fiber, digestible organic matter and starch content. Statistically insignificant difference between hybrids was at the percentage of the dry matter. Selecting the appropriate corn hybrid is therefore one of the most important measures for cultivation. The correct choice is key to improving the quality of forage for optimal production of livestock. Corn is one of the pillars of production of meat and milk. When choosing a suitable hybrid corn, it is necessary to take into account many factors. Each hybrid has certain characteristics and these must be respected, but also used for benefit. Not only to the price of seeds, but also the potential yield and utilization of nutrients is of great importance for the economy of the production
