Maintaining proper herd size, renovating pastures with a legume, fertilizing according to soil test, and
utilizing a rotational grazing system can aid in reducing summer forage shortages. However, during
drought conditions, the risk of having a short supply of feed still exists. Drought conditions during the last
couples of years have shown many cattle producers that summer is a critical time in a livestock operation.
You cannot only depend on perennial warm-season pastures to provide adequate forage during the
summer. It is time to start thinking about planting a few acres of warm-season annual forage grasses that
will serve as emergency forage. Selecting a type or variety of summer annual should be based on the
needs of individual livestock programs. Summer annual grasses have different growth characteristics
increasing moisture stress, and a reduced leaf
area at flowering may have led to decreased
yields. Thousand-seed weight was unaffected by
cutting date. Tiller density increased with later
cuts, but as inflorescence density remained similar, tiller fertility decreased. Seed purity was
unaffected by cutting date. Closing cuts had a
large, negative effect on inflorescence size, indicated by dramatic reductions in pure seed yield
per inflorescence with successive cuts. Seed germination percentage decreased following cutting
in September or October, resulting in lower pure
live seed yield. Closing cut dates between May
and August should be investigated.
