VETCHES AND VETCH-LIKE PLANTS 



485 



seed from 3 plats was 8.7 bushels to an acre. The plant 

 possesses no visible advantage over common vetch, and 

 there is no apparent reason why it should be recommended. 



593. Comparison of vetch species. On the Pacific 

 Coast all the vetch species are admirably adapted and in 

 California a number of them have been tested as green- 

 manure crops. In the data shown in the following table, 

 it will be observed that the yield of hairy vetch is small 

 if plowed under early, but if left to reach its maximum 

 growth exceeds the other species. To a less degree 

 common vetch shows the same lack of ability to grow in 

 cool winter weather. 



There is little to choose between the vetches in habit 

 and feeding quality where they all succeed well. On this 

 account preference is given mainly to those which have 

 good seeding habits, and consequently cheaper seed : -
