Pasture productivity in Iowa often is limited by the low yield of cool-season grasses in the summer. This project considers whether uneven seasonal distribution in pastures could be improved by including species that perform better under higher temperatures.
Does interseeding smooth bromegrass with alfalfa, birdsfoot trefoil, or kura clover improve pasture productivity and 2) Does rotating cattle to summer pastures consisting of with big bluestem or switchgrass improve season-long productivity?
The results indicate that interseeding bromegrass pastures with kura clover greatly enhances livestock performance. Kura clover was the only legume that persisted well over the five years the experiment was conducting. Rotating cattle to warm-season grasses in the summer gave inconsistent results depending on the weather.
