Since yellow clover is usually grown as an adjunct to permanent pastures, it can scarcely be called a rotation plant. But, like other clovers, it enriches the soil, and, therefore, should be followed by crops that are specially benefited by such enrichment, as, for instance, the small cereal grains. Yellow clover when sown is usually sown with other grass mixtures, and along with grain as a nurse crop; hence, that preparation of the soil suitable for the nurse crop will also be found suitable for the clover. It is, moreover, a hardy plant, insomuch that in some instances, if the seed is scattered over unplowed surfaces, as those of pastures, in the early spring, a sufficient number of plants will be obtained to eventually establish the clover through self-seeding. The seed is usually sown in the early spring, but in mild latitudes it may also be sown in the early autumn. It may be sown by the same methods as other clovers. (See page 267.) It is usually sown to provide pasture, the seed being mixed with that of other pasture plants before being sown. As the plants, like those of the small white variety, have much power to increase rather than decrease in pastures, it is not necessary to sow large quantities of seed, not more usually than 1 pound to the acre. But should the crops be wanted for seed, then not fewer than 3 to 5 pounds per acre should be sown and without admixture with other grasses or clovers. When the plants once obtain a footing on congenial soils, there is usually enough of seed in the soil to make a sufficient stand of the plants in pastures without sowing any seed, but since the seed is usually relatively cheap, where an insufficient supply in the soil is suspected, more or less seed should be sown. Since the stems of yellow clover plants become tough as the season of growth becomes considerably advanced, where it forms a considerable proportion of the pasture the aim should be to graze most heavily during the early part of the season. The plants do not make much growth during the autumn. It would probably be correct to say that it can grow under conditions more dry than are suitable for white clover, and, consequently, it is more uniformly prominent in evidence in permanent pastures when it has become established. Yellow clover is not a really good hay plant, owing to its lack of bulkiness. But in some soils its presence may add considerably to the weight of a crop of hay, of which it is a factor. This plant produces seed freely. The seeds are dark in color and weigh 60 pounds to the bushel. The seed matures early, usually in June or July, according to locality. The methods of harvesting, threshing and preparing the seed for market are substantially the same as those adapted in handling small white clover. (See page 272.)
