Great Plains Research: A Journal of Natural and Social Sciences
Our objective was to evaluate adaptation and compatibility of cool-season annual legumes overseeded into perennial grasses in the southern Great Plains. Freeze damage, vigor, and standing crop of 14 annual legume species were evaluated during spring at three locations in Oklahoma and Texas from 2006 to 2008. Across locations and years, standing crop of hairy vetch (Vicia villosa Roth) and Austrian winter pea (Pisum sativum L. ssp. arvense (L.) Poir.] averaged 3,513 and 3,210 kg dry matter (DM) ha-1, respectively. Standing crop of crimson clover (Trifolium incarnatum L.) and arrowleaf clover (T. vesiculosum Savi) averaged …
