DRY-FARMING 



The Great Wheat Groups. 



According to Jardine several htmdred 

 varieties of wheat, more or less distinct, 

 are groAvn in the dry-farming region of 

 the United States. The great bulk of 

 these varieties, however, fall into four 

 groups : 



I. The Hard Spring Wheats: (a) 

 Common Varieties, (b) Durum Va- 

 rieties. 



II. The Hard Winter Wheats. 



in. The Semi-Soft White or Inter- 

 mountain Wheats. 



rv. The Soft- White or Pacific Coast 

 Wheats. 



Broadly speaking each group is grown 

 in a particular belt or zone. These 

 wheat zones, of course, are not sharply 

 defined; still certain types predominate 

 in each.
