Yellow Blossom Clover Legume (Melilotus officinalis)

Yellow blossom clover, also known as sweet clover, is a tall biennial plant. It exists in two forms: one with white flowers and the other with yellow, with little distinction between them. Once established, it demonstrates aggressiveness, developing a substantial taproot and significant biomass.

Applications

In the UK, yellow blossom clover is commonly employed as a green manure species for soil improvement. It can also serve as a component in diverse grazing mixtures, contribute to pollinator-friendly planting, and, to a lesser extent, be utilized for game cover. In regions like the United States, it finds use in forage production.

Persistence

As a biennial, yellow blossom clover dies off after flowering. It can produce seeds and reappear in subsequent crops, but since the plants tend to be relatively scarce, their impact on the following crop is limited. However, precautions should be taken to prevent volunteers from contaminating future cereal crops. Even a small amount can result in coumarin taint, leading to rejection of malting barley.

Advantages

As a legume, yellow blossom clover fixes nitrogen in the soil. It possesses robust roots that contribute to soil structure improvement and, if allowed to grow for its full two-year cycle, yields substantial biomass.

Frost Tolerance

Yellow blossom clover survives the winter through its taproot, with leaves absent by the end of the season.

Yield

Hay yields of 6 – 7 tonnes of dry matter per hectare can be achieved.

Sowing Rate Recommendation

6 kilograms per acre – 15 kilograms per hectare.

Yellow blossom clover seeds are small and should be broadcasted or drilled at a shallow depth (not exceeding a few millimeters). Planting too deep dramatically reduces germination. Rolling the soil after sowing enhances seed-soil moisture contact.

Mixture Sowing Rate Recommendation

1 kilogram per acre – 2.5 kilograms per hectare.

This sowing rate is intended when using yellow blossom clover as part of a diverse grazing mixture.

Optimal Sowing Time

March – May is ideal for spring sowing, while mid to late August is recommended for autumn sowing. If sowing extends too far into September, establishment becomes less reliable.

Management

Yellow blossom clover does not tolerate severe topping, so it should be cut 10 centimeters above the ground to avoid damaging the plant crown. This may restrict weed control options. Limited information is available regarding pest and disease tolerance in yellow blossom clover. Observations suggest that it is more susceptible to sitona weevil and downy mildew compared to red or white clover.

Distinguishing Characteristics

Seed

The seed is round or oblong, typically beige to light green in color, with a smooth texture. Its length averages around 2 millimeters.

Seedling

The seedling produces a pair of blunt-ended cotyledons, roughly half the width of their length. The petioles, if present, are short. The first true leaf is more elliptical in shape, with softly toothed margins.

Flowering Plant

A vertically growing species that can reach up to 1.6 meters in height during its second year. Its trifoliate leaves resemble those of lucerne, with oblong leaflets. However, the terminal leaflet is attached to a longer petiole than the lateral leaflets. The apex of these leaflets may exhibit toothed edges. The stipule of yellow blossom clover is small, narrow, triangular, and sharply pointed, without toothed margins. The stems are vibrant green when young but become duller and woody in the second year. The inflorescence is long, consisting of separate clustered flowers attached by short stalks along a central stem (raceme). These flowers may be yellow or white. The plant has several deep taproots, and aerial growth emerges from a crown.

Additional Information

The average number of seeds per kilogram ranges from 420,000 to 570,000. The average protein content is 15-16%.

Compatible Companions

Yellow blossom clover can be cultivated alongside other legumes like red or white clover as part of a diverse mixture, or combined with chicory for a two to three-year game cover blend.
