Resumo: 	Forage yield of three species of leguminous forrages: alfalfa, Medicago sativa L.; red clover, Trifolium pratense L.; and birdsfoot trefoil Lotus corniculatus L. was evaluated in waterlogged soils in the VIIth Region, Chile, during four seasons with three fertilization rates: 2 t lime ha-1 + 150 kg P2O5 ha-1; no lime application + 150 kg P2O5 ha-1; and no lime + 70 kg of P2O5 ha-1, applying half of the fertilizer dose during the seasons following establishment. The experimental design was randomized complete blocks with four repetitions. An analysis of variance was carried out and means were compared using the Duncan test (P &amp;#8804; 0.05). Alfalfa needed high fertilization to achieve production comparable to birdsfoot trefoil and red clover, reaching its best production with complete fertilization in the first season (4.6 t DM ha-1). The red clover maintained high production until the second season independent of the fertilizer dose (11.8 t DM ha-1), but began to decline in the third season. The birdsfoot trefoil was the species best adapted to these soil conditions, DM yield was not affected by the dose of phosphorus in the four years, reaching production levels of 7.1 t DM ha-1 during the fourth season.
