【 摘 要 】

This study was carried out at Campo Experimental do Cerrado in Embrapa Amapá, Brazil, aiming to select, based on the agronomic characteristics of productivity, dry matter and nutritional quality of the forage, the accesses of species from the genus Paspalum that possess potentiality of use as forage plants. During the years 2000, 2001 and 2002, 21 accesses of grasses were evaluated, including 18 of Paspalum and three control species: Brachiaria decumbens, Andropogon gayanus cv. Baetí and Brachiaria brizantha cv. Marandú. The experimental design was complete randomized block with three replications. The variables studied were: production of dry matter, neutral detergent fiber on the dry matter, in vitro digestibility of dry matter and crude protein content in the dry matter. All the accesses showed marked reduction in productivity and quality of produced forage, when the climatic conditions became unfavorable, showing that Paspalum as the other tropical grasses have high seasonal production. Based on the variables studied, the selected accesses were P. guenoarum (BRA-014851), P. atratum (BRA-9661) and Paspalum sp. (BRA- 009407).
