Abstract

The sowing season has great influence on the establishment of forage, as spreading seeds out of season tends to harm productivity. Consequently, the aim of this study was to evaluate sowing seasons, production and bromatological quality of Brachiaria forage species in Mineiros-GO. The experiment was held at IPAF/FIMES, in a typical Quartzarenic Neosol. The experimental treatments consisted of five sowing dates and five cultivars/species of forage grass (Brachiaria brizantha (Hochst) cv. Marandú, Brachiaria brizantha cv. Xaraés, Brachiaria hybrid cv. Mulato, Brachiaria decumbens Stapfe and Brachiaria ruziziensis). The experiment was designed in randomized blocks with sub-plots, with four replications, each block represented by a sowing date. Dry matter production was higher in the first and second sowing dates. Cultivar Mulato achieved the highest productivity among the assessed cultivars. The sowing season and cultivars influenced the levels of crude protein, neutral detergent fiber and acid detergent fiber. It is concluded that a marked decrease occurs in dry matter production and bromatological quality of Brachiaria species when the sowing is done after mid-March.
