Sweet clover
Biennial white blossom sweet clover, seeded at the rate of 18 pounds of scarified seed to the acre in early spring, provides useful grazing in August and September of the same year and from May to August in the following year. It is more valuable as a substitute for permanent pasture than as supplementary pasture, for it makes its best growth at the same time as permanent pastures.
Marrow-stem kale
Few crops are available to provide additional feed in October, a time when it is often of great value. Marrow-stem kale is useful for this purpose. It is a cross between Kohlrabi and thousand-headed-kale and derives its name from the tall thick stem which contains a marrow-like pith. It is one of the most productive green crops available and is unusually high in carotin. Seed may be sown at the rate of about 3 pounds to the acre in April or May, in rows about 28 inches apart, and the best growth is made when the plants are thinned to from 6 to 9 inches apart. The crop may be cut and fed to stock on pasture or indoors. Marrow-stem kale is resistant to injury by frost, and usually remains in good condition for feeding until severe frosts in November.
