This study was carried out in Fazenda Canchim in Sao Carlos-SP, physical base of Embrapa Southeast Livestock, aiming to select, based on the agronomic characteristics of productivity of dry matter and quality of the forage, the accesses of suitable gender Paspalum for possessing potentiality of use as foraging plants. Were evaluated for 3 years, with 22 forage grasses, being 19 of Paspalum and three more of control species: Brachiaria decumbens, Andropogon gayanus cv. Baet and Panicum maximum cv. Tanzania, submitted to two intensification levels: high (fertilizer after each cut and supplemental irrigation) and low (only fertilizer of annual replacement without irrigation). The experimental design was of split blocks subdivided in the space and time with two replications. The studied variables were: dry matter production, in vitro dry matter digestibility and crude protein content. The results show that the accesses responded to the intensification level minimizing the negative effect of the stational production. Based on the studied variables, the selected accesses were: BRA-011401 (Paspalum glaucescens); BRA-011681 (P. atratum); BRA009661 (P. atratum) and BRA-019186 (P. regnellii).
