Establishment, Hay Yield, and Persistence of Two Sainfoin Growth Types Seeded Alone and With Low-Growing Grasses and Legumes1

Abstract

Abstract

‘Eski’ sainfoin (Onobrychis viciaefolia Scop.), a “one-cut” cultivar, and ‘Remont’ sainfoin, a rapid regrowth “two-cut” cultivar, were evaluated for hay production in pure stands and in mixtures with low-growing grasses and legumes on irrigated land over a 4-year period. Measurements were made of seedling establishment, yield, and persistence. Yields of Remont were slightly greater than those of Eski for the 4-year period. The difference in yield was primarily due to greater seeding year yields of Remont. Within a given year, Eski yielded more at the first harvest and less at the second harvest than Remont. Yields of both cultivars decreased in the fourth year due to a partial loss of stand.

Sainfoin mixtures containing either birdsfoot trefoil (Lotus corniculatus L.) or black medic (Medicago lupulina L.) were most productive and those containing Ladino or common white clover (Trifolium repens L.) least productive. The latter species were more competitive with sainfoin, particularly Eski, because of rapid regrowth following clipping.

Pure stands of both sainfoins were heavily invaded by dandelion (Taraxacum officinale Weber) in 1971, and mixtures of sainfoin with either birdsfoot trefoil, black medic, or common white clover were invaded to a lesser degree. Sainfoin cultivars grown with Ladino clover, Kentucky bluegrass (Poa pratensis L.) or red fescue (Festuca rubra L.) were not invaded by dandelion. The relative merits of the two sainfoin types are discussed.
