24 D1!Y-LAND GEAINS FOR NOETH AND SOUTH DAKOTA. 



CONCLUSIONS. 



For the region herein discussed, western North and Soutii Dakota, 

 the following conclusions are drawn: 



(1) The success of the dry-land farmer will depend very largely 

 upon the selection of varieties adapted to his conditions. 



(2) Durum wheat is a more profitable crop than common spring 

 wheat. The best variety is the Kubanka (G. I. No. 1440 or G. I. 

 No. 1516). 



(3) Winter wheat should be grown wherever it will survive the 

 winter. The best varieties are the Turkey (G. I. No. 3055) and the 

 Kharkof (G. I. No.' 1442). 



(4) Early or medium maturing varieties of oats, such as the Sixty- 

 Day, the Kherson, and the Swedish Select, should be grown. 



(5) Two-rowed barleys yield better than the six-rowed varieties. 

 The best two-rowed barleys are the Hanna (G. I. Nos. 24 and 203) 

 and the llannchen (G. I. No. 531). The best six-rowed barleys are 

 the Odessa and the Minnesota No. 6.
