Winged bean Psophocarpus tetragonolobus (68 accessions) and P. scandens (3 accessions) were evaluated at Homestead, Florida for potential use as a forage crop. CP content of 2nd yr vegetative growth was 11-32% (av. 22%) and nitrate content was 0.01-1.02%. Excessive growth was detrimental to sorghum seed set, but low vigour bean plants observed in the trial could be selected to produce a high protein mixed forage crop.
