Resumo

The aim of this work was to evaluate the agronomical characteristics, chemical composition and removal of potassium of five different genotypes of corn grown for silage. A split-plot complete randomized block design was used, with three hybrids (DKB 390, AGX 8517, A-2560) and two varieties (ALBianco, Piratininga), using two cut heights (20 and 40 cm above soil level) and four replications per treatment. After harvest, plants were analyzed for chemical characteristics and potassium (K). Milk production and DM intake were predicted for each treatment. There was an increase in DM content with the increase in cut height (p
