PEAS AND PEA-LIKE PLANTS 



447 



Experiment Station peas germinated best when planted 

 4 inches deep. Even when planted 8 inches deep, some 

 of the plants emerged. 



536. Development of the plant. Stewart at the Utah 

 Experiment Station has made a careful study of the com- 

 position of the Golden Vine pea at various stages of 

 growth, when grown under irrigation. Some of his results 

 are shown in the following table : 



537. Hay. Field peas are usually cut for hay when 

 the first pods are full grown but not yet filled, but cutting 

 may be delayed until the leaves begin to turn yellow. 

 This, however, will result in the hay containing many 

 seeds. 



At the Utah Experiment Station Golden Vine peas 

 cut in bloom gave a larger yield to the acre than when cut 

 late. 



The yield of hay from peas alone probably averages 

 less than 1 ton an acre. Partly on this account, and 

 partly because of easier harvesting, they are nearly al- 

 ways sown mixed with oats when intended for hay.
