Fig. 36. — The sorghums are grown for forage much farther north than for gi-aln ; 

 while the sweet sorghums, which are not commonly grown for grain, are frequently 

 nsed for forage far to the east in the Cotton Belt and the Com and Winter Wheat 

 regions. The acreage of soi-ghums for forage is larger than the acreage for grain, 

 ..«specially in Kansas, where some sorghum is used for silage (see Fig. 25). It is in- 

 teresting to note that the average yield per acre of sorghum forage was 1.7 tons in 

 1919, as compared with less than 1 ton per acre for corn in this area, and 1.2 tons for 

 corn in the entire United States. The sorghums, apparently, yield more forage per 

 acre in this semiarid area than corn in the humid regions.
