576. Feeding value. Little is definitely known of the 

 value of hairy vetch, as but few feeding experiments are 

 reported. Judged from chemical analyses alone its value 

 would apparently be the highest of all legumes. 



577. Use in rotations. Hairy vetch is well adapted 

 for use in a simple rotation with a summer crop, filling 

 practically the same place in this respect as crimson clover, 

 but hairy vetch is adapted to a much wider range of 

 climatic conditions. As a winter crop, it can well be 

 grown in rotation with such summer crops as sorghums, 

 millets, late-planted corn, cowpeas and soybeans. In some 

 southern states it is commonly grown in rotation with 

 Johnson-grass. Johnson-grass sod is plowed in the fall, 

 and the hairy vetch then planted usually with oats. 

 The oat and vetch hay can then be cut in May, and fol- 

 lowing this, two crops of Johnson-grass hay can be secured. 

 A fall plowing is not only necessary for the planting of 

 the vetch and oats, but increases greatly the yield from 

 the Johnson-grass. In the Northern States a crop of 

 vetch hay can be cut early enough to grow a crop of 

 millet hay the same season. 



The practice of planting hairy vetch in corn at the 

 last cultivation is increasing. The vetch is often more
