The contribution of biological nitrogen fixation (BNF) to the N nutrition of six annual forage legumes, subterranean clover ( Trifolium subterraneum), burr medic ( Medicago polymorpha), balansa clover ( Trifolium michelianum), Persian clover ( Trifolium resupinatum), yellow serradela (Ornithopus compressus), and pink serradela ( Ornithopus sativus) was evaluated by the N-15 natural abundance technique, using four grass species (Briza maxima, Bromus mollis, Hordeum berteroanum, Avena barbata) and two composite species (Leontodon leysseri and Hedipnois cretica) as reference plants. An additional objective was to determine whether alternative legume species to those in common use ( T. subterraneum and M. polymorpha) in the area, could improve BNF. The field studies were conducted in two edaphic conditions, granitic (Entisol) and clay (Vertisol) soil, located in Cauquenes, VII Region, in the sub-humid Mediterranean zone of Chile. In the granitic soil the percentages of N derived from fixation were high in all species ( 74 to 94%); yellow serradela cv. Tauro presented the greatest N content in dry matter and N fixation, equivalent to 91 kg N ha(-1). In contrast, pink serradela cv. Cadiz and subterranean clover cv. Gosse presented the lowest N fixation. In the clay soil, under periodically waterlogged conditions, balansa clover cv. Paradana and persian clover cv. Prolific had high percentage values of BNF (> 95%) and fixed more N (100.2 and 82.5 kg N ha(-1), respectively) than burr medic and subterranean clover cv. Gosse. The present study allowed the identification of new germplasm of high capacity of N fixation which is an additional criterion for selecting species for infertile and waterlogged soil conditions in the Mediterranean area of Chile.
