摘要

Eighteen legume accessions were tested over three growing seasons on a previously controlled grazing site and a communal grazing management site. Within sites, there were two soil wetness blocks - namely, vlei and topland. Generally, the vleis produced better establishment in season 1. Most legume counts drastically declined in seasons 2 and 3 on all sites except for uncontrolled topland where some legume accessions increased significantly, including Aeschynomene villosa cv. Reid, A. villosa cv. Kretschmer, Chamaecrista rotundifolia cv. 93094 and C. rotundifolia cv. Wynn. Biomass production was very low for most legumes across all sites and the promising accessions were C. rotundifolia cv. 93094, C. rotundifolia cv. Wynn, C. pilosa, A. villosa cv. Reid and A. villosa cv. Kretschmer. While the results were not very encouraging, the C. rotundifolia accessions are worth pursuing on communal toplands, while the A. villosa accessions could be tried on the other sites.
