Abstract

Pasture productivity in Iowa is often limited by low productivity of cool-season grasses during summer. This uneven seasonal distribution of for age production could be improved by including species in pasture systems that perform better under higher temperatures. Warm-season grasses produce most of their growth during summer when cool-season grasses are semi -dormant. By using cool-season and warm-season pastures in a sequential system it should be possible to improve seasonal productivity. The overall objective of this project i s to evaluate the productivity of sequential grazing system s for beef cattle production in Southern Iowa. Specific objectives are to: 1) evaluate the impact of legumes on the productivity of cool-season pastures grazed in the spring and fall, 2) evaluate warm-season grasses f or summer grazing, and 3) determine the effects of pasture sequence on the productivity of season-long grazing systems.
