Abstract

Grasses from genus Brachiaria are widely used for grazing systems in the Northwest of Paraná, as well as throughout Brazil. Marandu palissadegrass is the most used cultivar, but there are some options that need to be evaluated. The objective of this study was to evaluate forage mass, morphological characteristics and sward heigth (at 95% canopy light interception) of five Brachiaria brizantha cultivars (Marandu, Xaraés, Piatã, Paiaguás and MG-4) and Brachiaria hybrid Convert HD 364. A completely randomized design was used, with six treatments and four replicates. Sward height, light interception, forage mass and morphological composition were evaluated. The cultivars Xaraés, Paiaguás and MG-4 stood out for the greater total and leaves forage mass, particularly in the dry season. These materials are good alternatives for the Marandu cultivar. The pre-grazing sward height recommended for cultivars Marandu and Piatàwas 25 cm, Xaraés and MG-4 is 30 cm, Paiaguás 34 cm, and Convert 23 cm.
