Under in situ dry season grazing horse gram gave steer rates of liveweight gain (RLWG) of from 0.25 to 0.64 kg head–1 day–1 over four years for periods of from 63 to 98 days. RLWG was strongly correlated with horse gram and total nitrogen yields. Effective stands lasted for only two seasons from each planting. The early maturing cultivar Leichhardt gave higher pulse yields than the midseason accession Q6837 but had larger seeds and slightly lower hard seed content. There was no difference in the persistence of the two lines. A light cultivation in the late dry season increased seedling regeneration over the next wet season, especially of Leichhardt.
