FORAGE PRODUCTIOX 



be divided into perennials and annuals, the former class 

 including such plants as alfalfa and the clovers^ and the latter 

 the cowpea, soy bean, field pea, and vetch. A few miscel- 

 laneous forage crops, usually used for soiling or pasture pur- 

 poses, are included in the mustard family, the Crucifereae. 

 These are rape, kale, cabbage, and kohl-rabi. Other plants 

 are occasionally used as forage crops, but they are com- 

 paratively unimportant. 



327. Forage Production in the United States. The more 

 important kinds of forage are indicated in Table XIV, which 

 shows the acreage, production, and value of the different 

 classes of forage produced in the United States in 1909. This 

 table shows that the most important class of forage is mixed 

 timothy and clover hay. Next to this in acreage and pro- 

 duction ranks the class which includes wild, salt, and prairie 

 hay. Timothy hay without an admixture of clover ranked 

 third in acreage and production and second in value. Other 

 important classes of forage are alfalfa hay, coarse forage 

 (fodder and silage corn, sorghum, etc.), grains cut green for
