Abstract

The dynamics of warm-season grass and legume plant communities are affected by grazing landscape and soil type. This project explored how these factors could be managed by western Iowa farmers to successfully establish higher-quality summer pastures comprised of warm-season grass/legume mixtures.

Key Question

Can the productivity of warm-grass pastures be improved by interseeding legumes?

Findings

The results suggest that in western Iowa, interseeding switchgrass or big bluestem pastures with legumes has an adverse impact on the grasses due to early season competition from the legume. Stands of both warm-season grasses were signifi­ cantly reduced by interseeding legumes, and for this reason it should not be a recommended practice.
