106 WHEAT 



6. Wheat, kafir (or other sorghum), fallow- 

 three year rotation. 



7. Wheat, wheat plus green manure, kafir, 

 fallow four year rotation. 



8. Wheat (2 years), kafir, green crop with 

 fallow four year rotation. 



9. Wheat, corn (or other forage), oats plus 

 green manure, fallow four year rotation. 



10. Wheat, corn, cowpeas with fallow three 

 year rotation. 



Alfalfa may be grown successfully and used in 

 rotation in the more favorable soils of the semi- 

 arid regions. The first five plans are adapted to 

 the northwestern spring wheat area, where it 

 is difficult to use leguminous or green manuring 

 crops. The last five may be successfully prac- 

 ticed in Kansas and the southwest in the growing 

 of winter wheat. Plan No. 6 is now being prac- 

 ticed on the 3,600 acre experimental farm at 

 Fort Hays. One-third of the tilled upland on 

 this farm is planted to wheat each year, one-third 

 to intertilled and forage crops, mainly kafir, milo 

 and sweet sorghum, and one-third remains fallow 

 each year, making no crop and receiving summer 

 culture. During the year of fallow the land should 

 receive a dressing of manure, or early planted crops 

 may be plowed under for green manure. Wheat 

 follows the summer fallow and the forage crops 

 and the sorghums follow the wheat, thus every 

 year the great income producing crop, wheat, is 

 grown under the most favorable conditions. Where 

 conditions are more humid two or three crops of 

 wheat may be raised after fallow before the field 

 is planted again with sorghums.
