76 WHEAT 



By following a good systematic rotation where the fields 

 are treated with manure at least once in four years and 

 also have a cultivated and leguminous crop grown during 

 that time, the ground will be kept in a good state of fer- 

 tility and paying crops of wheat can be obtained. 



By growing the wheat crop only one year in four, insect 

 enemies and diseases that usually prey upon the crop will 

 be eliminated from the soil. The cultivated crop grown 

 during the rotation will eradicate the weeds and retain 

 moisture ; and the leguminous crop will add nitrogen and 

 humus to the soil, which are so necessary in wheat growing. 



Enemies. Some of the enemies of wheat that have 

 prevented good yields in the past are rust, smut, scab, 

 Hessian fly, jointworm, chinch bug, army worm, midge, 

 stem maggot, wireworm, weevil, and grain moth. 



The treatment for wheat smuts is the same as that used 

 for the barley smuts, as outlined in the next chapter. The 

 other wheat pests are partially controlled by rotation and 

 time of seeding.

Count out the kernels not true to type into three grades. In
