=Barley= is grown chiefly in the states of Minnesota, California, Wisconsin, North and South Dakota, in the order named, these states raising seventy-five per cent of the output grown in the United States. It is used as food for live stock, and as an article of commerce is in demand principally for the making of malt in brewing beer, but in California and other western states, where Indian corn does not flourish, barley is used as a substitute grain for horses and mules. About two bushels to the acre are sown in the spring, with a drill or a broadcast seeder. It is admirably adapted as a nurse crop, as it stands up well and does not shade the ground so much as many other plants.
Barley for malting should be cut before fully ripe and put in well-capped shocks to cure; the price paid is largely governed by the color acquired in curing, which should be bright. A bushel weighs forty-eight pounds, and the yield is from twenty-five to forty bushels per acre.
=Buckwheat= (_Fagopyrum esculentum_) is a grain of minor importance, its flour being used as human food, mostly in the form of griddle cakes. The plant is esteemed for plowing under in summer, to supply humus, and its blossoms for the honey bee. Most of it is grown in New York and Pennsylvania, and it does well in soils too poor for most other crops. It is sensitive to frost, and used as a sort of catch crop, sown generally about the beginning of July, broadcast. Forty bushels, weighing forty-eight pounds per bushel, is a maximum yield.
=Clover= (_Trifolium pratense_). In the states east of the Missouri river _red clover_ is highly esteemed. It has much the same qualities as alfalfa, except it is a biennial, enduring but two years without re-seeding and at best gives two cuttings of hay per year, aggregating two to three tons. It is from the second cutting that seed is usually saved. Four quarts of seed is a common quantity to sow per acre. Red clover makes excellent hay, except for horses. Its seed, like that of alfalfa, weighs sixty pounds per bushel, and its yield is from one to five bushels per acre.
WHITE CLOVER (_Trifolium repens_) is a very useful pasture and honey plant, but is not used for hay. It spreads rapidly, and is widely used for sowing with other pasture grasses.
