this clover will tolerate. Strawberry clover has been 

 observed making good growth in association with 

 saltgrass and sedges in locations where the salt 

 content of the soil was more than 1 percent (fig. 2). 

 In established stands, plants have survived salt con- 

 centrations of over 3 percent for long periods. Under 

 such concentrations, however, little growth is made. 

 After the salt concentration is reduced by flooding, 

 the plants renew growth. 



The salt tolerance of seedling plants is greater 

 under cool temperatures than under warm tempera- 

 tures. 



VARIETIES 



Most of the named varieties of strawberry clover 

 originated in Australia. Limited trials indicate that 

 Australian varieties are better adapted west of the 

 Cascade Range and the Sierra Nevada than in the 

 region between these mountains and the Rocky 

 Mountains. Palestine is larger and more productive 

 than other Australian varieties tested, but it lacks 

 winter hardiness. 



Little research has been done in the United States 

 on the improvement of strawberry clover. Salina, 

 developed and released by the California Agricul- 

 tural Experiment Station, is the only named variety 

 that originated in the United States. It originated 

 as plant selections from the Palestine variety. Salina 

 is better adapted to California conditions than is 

 Palestine. 



Most of the seed available from the seed trade is 

 harvested from strains naturalized in the region be- 

 tween the Cascade Range and the Sierra Nevada 

 and the Rocky Mountains. These strains are similar 

 in growth characteristics. Try to obtain seed pro- 

 duced under conditions similar to those in your 

 locality. 



SEEDBED PREPARATION 



Prepare seedbeds in the fall; this permits early 

 spring planting and thereby helps strawberry clover 

 to get established ahead of competing vegetation. 



Where possible, plow or disk thoroughly, then 

 harrow to level and firm the soil. If the soil is too 

 wet for tilling, the vegetation should be mowed and 

 removed. L\
