Resumo:  ABSTRACT This study aimed to evaluate the production of two pasture species, Brachiaria brizantha cv. BRS Piatã and Panicum maximum cv. Mombaça, under different irrigation depths. The experiment was carried out from May to December 2014, at the State University of Maringá, in the municipality of Cidade Gaúcha-PR, Brazil. The experiment was set out in a strip-plot design, with four replicates, six irrigation depths in the plot and two pasture species in the subplot. Irrigation depths were represented by a percentage of reference evapotranspiration (ET0), which was estimated by the Penman-Monteith equation. Four pasture cuts were performed during the studied period and there were no differences between the yields of both evaluated pasture species; however, irrigation depths caused a quadratic response on pasture yield. The maximum values of dry matter yield of the pastures under irrigated conditions were 52.1, 41.6, 26.2 and 25.1% higher than under non-irrigated conditions, for the 1st, 2nd, 3rd and 4th cuts, respectively. Irrigation depths that applied water volumes close to ET0 promoted considerable increases in pasture yield.
