Inter-Planted Crops 137 



are adapted to a rather narrow belt which includes northern 

 Florida, southern Georgia and westward, taking in the 

 southern half or more of Texas and to the Pacific coast, 

 with most of California in the area. The New Mexico 

 Experiment Station ^ reports that when seeded during the 

 fall months, the vines were too succulent and tender to sur- 

 vive the winter, but w^hen seeded any time from December 

 to March the growth was not injured and a good quantity 

 of herbage was available for turning under by the middle of 

 May. 



Probably field peas have been used more for orchard pur- 

 poses in southern California, in the citrus groves, than 

 elsewhere. O'Gara reports favorable results in the Rogue 

 River Valley in Oregon when used as a spring crop for orchard 

 purposes. Moreover, seeding may be done in most parts 

 of the country at the time of the last cultivation in July or 

 August, but except in the far South and in California the 

 vines w^ill be killed late in the fall by low temperatures, 

 though light frosts will not injure them. The vines decay 

 quickly and leave the soil and subsoil in excellent condition. 



The large vigorous growing Marrowfat varieties, such as 

 Canadian Beauty, Arthur, Paragon, Wisconsin Blue, and 

 others, are suitable for orchard purposes. 



x\bout 2 to 2| bushels of seed to the acre are required 

 when broadcasted, though 3j bushels of the very large- 

 seeded varieties are needed, while Ij to 2 bushels of the 

 small-seeded sorts will suffice. Grain-drills are some- 

 times used in seeding, in which case a smaller quantity of 

 seed is required. The seed should be covered from 2 to 4 

 inches deep, depending on whether the soil is heavy or light. 



As the vines mat down very densely, it is an advantage
