414 APPENDIX 



OREGON 



In the western portion of the state, on farms where general agriculture 

 is practised, the rotation is usually with the cereals and clover or vetch; for 

 instance, wheat, oats, clover for two years, or a crop of winter vetch. In 

 the dairying districts corn is grown in a rotation with clover and cereals. 

 In the Columbia River basin in eastern Oregon, the practice is grain growing 

 exclusively; usually wheat, bare fallow, and wheat again. In sections where 

 the rainfall is greater, some farmers follow wheat with barley, then the bare 

 fallow.

PENNSYLVANIA 



Probably corn, oats, wheat, grass, the latter including more or less clover, 

 is the most common rotation. In some parts of the state another year of 

 of grass is added. In the southern part, notably in the Cumberland Valley, 

 the common rotations are: Corn, oats, wheat, wheat, grass; and corn, wheat, 

 wheat, grass. In the tobacco districts various short rotations are practised 

 according to the soil conditions best adapted to the growth of this crop.

RHODE ISLAND 



The usual practice is to break up sward land and plant potatoes and corn, 

 sometimes reversing the order of these two, sometimes introducing a crop 

 of millet or oats for another season, and then seeding either with or without 

 winter rye or oats. The land is allowed to continue in grass upon most farms 

 so long as there is anything worth cutting. The following rotations are in 

 progress at the Experiment Station: (1) Oats sown in the spring, with 

 common red clover; clover; potatoes, and winter rye sown after the potatoes 

 are harvested; winter rye cut green and followed by Hubbard squashes; 

 onions. (2) Winter rye; timothy and red top seed sown with rye and 

 common red clover sown on the surface the following March; clover and 

 grass; grass; grass; Indian corn; potatoes. (3) Winter rye; common red 

 clover (seed sown in March of the previous year) ; potatoes.

SOUTH CAROLINA 



Very little rotation is practised here. The main crops raised are corn 

 and cotton. The bottom lands are usually planted to corn year after year 

 and the uplands planted year after year to cotton. Cotton can be contin- 

 uously grown on the same land without diminishing the yield provided the 

 seeds are returned on the soil. But the continuous growing of cotton on 

 uplands diminishes the fertility rapidly; chiefly because the clean cultivation 

 that is required for this crop permits the soil to wash badly. We recom- 

 mend a rotation of corn with cowpeas, and a cover crop of rye; wheat or 

 winter oats; cowpeas, with a rye cover crop; cotton. We have a small 

 section in which tobacco is grown; for this crop we recommend tobacco, 

 with a rye cover crop; corn and cowpeas; oats; cowpeas; rye, with a cover 

 crop; cotton.
