Kura clover is known for its longevity once established. However, its use in pastures has been limited by a reputation for being slow to establish. Kura clover (Trifolium ambiguum cv Endura) was planted into a dessicated wheat cover crop in southeastern Ohio on 18 Apr 2002 using a no-till drill. Grass seed was planted either in spring with the kura or no-till drilled on 19 Sep 2002. Treatments also included nitrogen (0 or 50 kgN/ha) in May 2002. Grass seed planted with the kura included Duo festulolium, Tekapo orchardgrass, Bronson tall fescue, Quartet perennial rye, and “Virginia Mix” (20% Tekapo, 40% Quartet, 40% Duo). All treatments were subjected to rotational grazing and mowing after establishment. Measurements included seedling establishment in first season, botanical composition, survivability of grasses and kura, and total forage mass. Data will be used in conjunction with the Integrated Farm Systems Model to model pasture characteristics of kura clover and to predict farm productivity and economic impacts of establishing kura clover in cattle pastures.
