If melons are to be grown as one of the crops in a regular rotation, they should follow the leguminous crop that is grown for the purpose of adding humus and nitrogen to the soil. In regions where winter wheat and clover are grown, a rotation of wheat, clover, and melons is highly satisfactory. Another good rotation is oats, clover, melons, and corn. In regions where clover does not thrive and wheat and oats are not grown, a rotation of corn, cowpeas, and melons may be employed, or the rotation extended by seeding to grass after the melons are harvested.
