A work was conducted in 1978/79/80 in the area of Instituto Agronômico do Paraná (IAPAR) Ponta Grossa, PR, Brazil, to verify the forage crop potential of four subtropical grasses: Hemarthria altissima, Paspalum notatum cv. IPEAME, Cynodon plectostachyus and Setaria anceps cv. Nandi, isolated and in association with one of the following legumes: Desmodium intortum cv. Greenleaf, Macroptilium atropurpureum cv. Siratro, Galactia striata, Neonotonia wightil cv. Cooper and Lotus corniculatus cv. São Gabriel, disposed in a split-plot design with three replications. During the time of observation, a total of 3 t/ha of dolomite lime, 540 kg/ha of hiperphosphate, 550 kg/ha of superphosphate and 200 kg/ha of potassium chloride were applied in all plots. The annual productions of dry matter and crude protein from some associations were significantly higher than the productions of grasses that were planted isolated. The grasses associated with the legumes always showed better proteic value than the isolated grasses.
