Cotton is one of the greatest cash crops, and while it should be the main money crop in the boll weevil territory north of latitude 32, it should not be the only cash crop grown. The safest plan either within or without the boll weevil territory is to follow a system of diversified farming. The cotton farmers, especially those in the boll weevil territory, cannot afford to depend entirely on cotton as a cash crop. A system of rotation suitable for cotton belt farmers should include some of the following staple crops: _Oats are probably_ the surest and best paying small grain crop that can be grown over practically the entire cotton belt. The same soil that will produce one bale of cotton per acre will grow 60 bushels of oats. At the average price that has prevailed for oats during the past five years, the 60 bushels will sell for $36 to $40, and the straw, when baled, will often pay the larger part of the expense of growing the grain. _The bale of cotton per acre land_ will produce about $30 worth of oats, at least one and a half tons of lespedeza hay, and five bushels of lespedeza seed. The lespedeza hay will sell for about $12 per ton and the lespedeza seed for about $3 per bushel. The total is $63 per acre. We are personally acquainted with a farmer who has averaged $65 per acre for eight years. _Thirty dollars worth of oats_ and twenty bushels of soy beans at $1.50 per bushel, and one and a half tons of soy bean hay at $8 per ton, means $72 per acre. These are very conservative figures. At the Mississippi Delta Experiment Station in 1912 the land produced ninety bushels of oats to the acre, twenty-two and a half bushels of soy beans, "after losing a good percentage of the beans by shattering," and 5,200 pounds of soy bean hay. The average yield of cotton on the same land was about 500 pounds of lint per acre. [Illustration: Oats in a three-year rotation with cotton and corn] _Oats and vetch_ sown together furnish more and better grazing and better hay than either when sown separately. There is no better hay than oats and vetch cut in the dough stage. Few hays will sell for a better price on the market. The oat and vetch hay provides a much more satisfactory ration for horses and mules than corn or leguminous hay. _Oats may be followed by cowpeas._ When the cowpeas are planted in rows on good land, well fertilized and cultivated, the yield is usually from ten to twenty bushels of peas and one and a half tons of hay. The peas usually sell for about $2 per bushel and the hay for about $12 per ton. _Ninety bushels of oats_ and sixty-seven bushels of peanuts were produced on the same land at the Mississippi Delta Experiment Station in one year. At the present prices for peanuts and peanut hay, it is a very profitable crop to grow after oats when properly handled.
