Productve behavior of Holcus lanatus populatons in Santa Catarina, Brazil

Abstract

The objectve of this study was to evaluate genotypes of Holcus lanatus L. regarding forage producton, persistence and seasonal distributon. Two experiments were carried out in two different locatons of Santa Catarina State (in the municipalites of Canoinhas and São Joaquim) in 2009-2010. Treatments were arranged in a randomized complete blocks split-plots design with four replicatons. In Canoinhas there was no difference among Holcus lanatus genotypes in dry mater producton. The seasonal distributon presented biannual behavior with producton concentraton in winter. In São Joaquim, where Holcus lanatus producton showed perennial behavior, its genotype ‘Urubici Morro da Igreja’ presented a higher producton compared to the commercial cultvar. The species presented concentraton of dry mater producton in spring. Comparing the two locatons, Holcus lanatus showed larger potental use in the São Joaquim region.
