Abstract
A field-plot experiment investigated the re-establishment and productivity in 1987 (following wheat (Triticum aestivum) in 1986) of burr medic (Medicago polymorpha) and subterranean (sub-) clover (Trifolium subterraneum), which were each sown with 0, 20, 40, 60, 80, or 100% grass in 1985. There was no difference in the amount of dry matter production by medic or sub-clover over the whole growing season but medic was more productive earlier and sub-clover more productive later. Grass generally had little effect on legume or total dry matter production at proportions <40%, though medic productivity was slightly more vulnerable to the effect of grass-infestation than sub-clover.
