CROPS FOR DRY-FARMING 243 



Tennessee Winter, which is already well distributed 

 over the Great Plains district. 



Rye is one of the surest dry-farm crops. It yields 

 good crops of straw and grain, both of which are valu- 

 able stock foods. In fact, the great power of r3^e to 

 survive and grow luxuriantly under the most trying 

 dry-farm conditions is the chief objection to it. Once 

 started, it is hard to eradicate. Properly cultivated 

 and used either as a stock feed or as green manure, 

 it is very valuable. Rye occurs as both spring and 

 winter varieties. The winter varieties are usually 

 most satisfactory.

 liarly adapted to semiarid conditions. Emmer is 

 a species of wheat to the berries of which the chaff 

 adheres very closely. It is highly prized as a stock 

 feed. In Russia and Germany it is grown in very 

 large quantities. It is especially adapted to arid and 

 semiai'id conditions, but will prol^ably thrive best 

 where the winters are dry and summers wet. It 

 exists as spring and winter varieties. -\.s with the 

 other small grains, the success of emmer will depend 

 largely upon the satisfactory development of winter 

 varieties. 



Corn 



Of all crops yet tried on dry-farms, corn is perhaps 

 tlie most uniformly successful under extreme dry 

 conditions. If the soil treatment and planting have
