Rye
Rye seems to be rather a new crop as compared with wheat and barley. Specialists consider rye to have been found first as a weed in wheat in central Europe. Then it was separated from the wheat and used as a new crop. It seems to have been cultivated first in western Asia and southern Russia.
Soil requirements of rye are not as exacting (взыскательный) as those of other small grains. It is more productive on infertile, sandy, or acid soils than wheat, oats, or barley. Rye often is the only small-grain crop that can be grown successfully on sandy soils, but it grows best being sown in a well-prepared, firm seedbed.
There exist both winter and spring varieties of rye. However, the latter are less productive than the former and are grown to only a limited extent. Spring rye should be sown at the time spring wheat is seeded, when the ground can be worked. The time of seeding winter rye will depend on the use to be made of the crop.
The usual depth of seeding is from 1/2 to 2 inches. The depth will vary with the type of soil and season. On sandy soils and in dry seasons the seed should be placed deeper. Better results are usually obtained from seeding with the drill than from broadcasting the seed. The former method is almost universally practiced.
Rye is harvested in the same manner as other small grains.
