While there are a large number of varieties of the soy bean

While there are a large number of varieties of the soy bean, only about a dozen are commonly grown. They differ mainly in the color, size, and shape of the seeds, and in the time needed for ripening. Some of the varieties are more hairy than others.

Soy beans may take many places in good crop-rotations, but they are unusually valuable in short rotations with small grains. The grains can be cut in time for the beans to follow them, and in turn the beans can be harvested in the early fall and make way for another grain crop.
