Growth of Introduced Temperate Legumes in the Edwards Plateau and South Texas Plains

A study was conducted to evaluate production of 2 temperate, annual legumes at locations where temperature and moisture may seasonally place severe constraints on growth. Arrowleaf (Trifolium vesiculosum Savi) and subterranean (Trifolium subterraneum L.) clovers were grown at Beeville, in south Texas, and at Brady, 230 miles north of Beeville. Standing crop samples were collected at approximately 2-week intervals, starting 30 days post emergence and continuing to plant maturity during 2 years. Very little growth was made prior to 1 March at Brady in either year or at Beeville the first year. Total production was minimal (
