Abstract

Eight accessions of perennial Arachis spp. were planted into Argentine bahia grass (Paspalum notatum) swards at Grafton, in northern NSW. These accessions were measured over a 9-year period for dry matter production, rate of spread and nitrogen, phosphorus and potassium concentration.
The Arachis glabrata accessions, particularly CPI 19898, 22987, 58111 and 22762 had the greatest dry matter production and highest rates of spread over that time. Arachis pintoi cv. Amarillo, the only commercially available Arachis in Australia, had high dry matter production in the early years but this decreased markedly with time. Arachis repens persisted poorly.
