APPENDIX 415 



SOUTH DAKOTA 



No very definite methods of rotating crops have yet been adopted. In 

 the dryer central and western portions of the state it is important, if not 

 essential, that small-grain crops be alternated with cultivated crops or with 

 summer fallow handled to conserve moisture. In the eastern and south- 

 eastern portions of the state, where moisture is more plentiful, a sod crop 

 is needed in the rotation. Some suggested rotations are: (1) Wheat, brome 

 hay three years, flax, wheat, corn. (2) Barley, millet, wheat. (3) wheat, 

 corn, oats. (4) Wheat, corn (manured), wheat, oats. (5) Wheat, oats, 

 corn, flax, millet.

TENNESSEE 



A rotation often followed is corn, alone or with cowpeas, wheat, grass or 

 grass and clover. This rotation is adapted to east and middle Tennessee, 

 and parts of west Tennessee. Short rotations of wheat and clover, and of 

 wheat and cowpeas are also practised to advantage. A good rotation for 

 cotton is: Cotton; corn, and peas; a cereal (usually oats); cowpeas. Two de- 

 sirable pasture rotations for sheep and hogs are; (1) Barley, (sown in 

 August); sorghum; rape; cowpeas. (2) Clover, either red or alsike, sown 

 in August or early in September; rape or barley or spring oats, followed by 

 soy beans or cowpeas.

TEXAS 



The common rotation in this state is corn and cotton. In a considerable 

 portion of the state, notably the black-land section, alfalfa and cowpeas 

 are added to this rotation. We have no grass crops that can come into our 

 rotations; therefore, for the most part, our soils are covered with intertillage 

 crops. In some sections peanuts are grown, in other sections potatoes have a 

 place. Nearly all the legumes are grown with considerable success. In the 

 north Texas black-land country is a four-course rotation of corn, wheat, oats, 

 and cotton.

There is little systematic rotation of crops, largely because our soil is 

 still nearly virgin. Among sugar-beet growers a common rotation is: Beets, 

 manure applied in the fall ana plowed; beets; alfalfa, with oats for a nurse 

 crop; alfalfa, third crop plowed under as a green manure; beets. Sometimes 

 an oat crop follows alfalfa previous to seeding the beets. A better rotation 

 is: Sugar oeets, manure applied in the fall and plowed under; beets; field 

 peas with or without oats; sugar beets; corn or potatoes; alfalfa and oats; 

 alfalfa, with third crop plowed under; sugar beets. Where it is desired 

 to grow such crops as tomatoes and possibly wheat, or any other main^ crops, 

 they can be supplied in place of oats, potatoes, or sugar beets, in this 

 rotation. In dry farming the usual method at present is to grow wheat two 

 years out of three, the land being summer-fallowed one year in three. 

 Occasionally wheat is followed by barley or oats. A better system is : Wheat, 

 potatoes if possible, or com; wheat; field peas; barley; summer fallow; wheat.
