A study of two strains of Rhodes Grass (Chloris gayana Kunth.) and of Leucerne (Medicago sativa L.) as components of a mixed pasture at Lawes in South-east Queensland

Abstract

The results of investigations with Rhodes grass and lucerne as components of sown pastures at Lawes in south-east Queensland are reported. Two strains of Rhodes grass, differing very markedly in growth form, rate of maturity, and other characteristics, were shown to be virtually of the same value when grazed by cattle under a system of intermittent grazing at a heavy rate of stocking. It was shown that lucerne could be maintained in a mixed pasture with Rhodes grass, and that the presence of a small population of lucerne, of a density of 2-4 plants per square yard, resulted in Increased growth of Rhodes grass and increased live-weight gains by the steers. Reasons for these increases are discussed.It is considered that the mixture, which can be expected to give improved grazing mainly during the summer months, has possibilities for large areas in south-east Queensland.
