Hairy Vetch 



Hairy vetch grows in all regions of the United States, but the largest 

 acreages are in Washington and Oregon, and in Oklahoma, Texas,- and 

 States eastward to the Atlantic. It does well on fertile sandy soils and rich 

 loams. In the Cotton Belt it provides early spring grazing and serves as a 

 soil -improving cover crop. In more northern latitudes, hairyvetch may be 

 seeded alone o * with small grains to provide seed or hay. It is also used 

 in these areas for pasture and soil improvement. 



Common Vetch 



Common vetch is adapted to the same general area and soil conditions 

 as hairy vetch, but it is less winter hardy. It occasionally winterkills in 

 western Oregon and Washington and frequently winterkills in the northern 

 sections of the Cotton Belt. In Washington and Oregon it is grown as a hay 

 and seed crop, and for green manure, silage, and pasture. In the South- 

 eastern States it is used largely for green manure. 



Willamette is the most winter -hardy variety of common vetch, is 

 vigorous growing, and is adapted to Washington, Oregon, and to all 

 States east of the Mississippi and south of Tennessee. 



Purple Vetch 



Purple vetch- -the least winter hardy of the vetches --is grown in the 

 milder sections of California and Oregon, where it serves as a pasture, 

 green manure, or hay crop. 



Hungarian Vetch 



Hungarian vetch is grown in Washington and Oregon where it is espe- 

 cially well adapted to' heavy clay soils. In this region it is grown for hay, 

 silage, green manure, pasture, and seed. 



Woollypod Vetch 



Woollypod vetch is similar to hairy vetch in appearance and adapta- 

 tion but is slightly less winter hardy. It is more productive than hairy 

 vetch in the Southeastern States. Seed stocks are limited but are being 

 increased in the Western States.
