CRIMSON CLOVER AND OTHER ANNUALS 429 



In these states it is well adapted both to the sandy soils 

 of the coastal area and the clayey soils of the Piedmont. 

 Elsewhere in the United States it is but little grown. 

 In the states above mentioned, the total area planted in 

 1909 was about 50,000 acres, basing this on the assump- 

 tion that crimson clover was f of the " clover " acreage 

 in Delaware ; f in New Jersey, J in Maryland, J in Vir- 

 ginia and ^ in North Carolina. 



516. Variability and agricultural varieties. Crimson 

 clover is conspicuously variable in two respects ; namely, 

 the color of the corolla and the life period. In a single 

 field of crimson clover, plants may be found with white, 

 rose, crimson and variegated crimson and white flowers. 

 As crimson clover is mainly self-pollinated, such varieties 

 are easily selected and established. 



At the present time European seedsmen offer five 

 varieties ; namely, extra early, ordinary, late and extra 

 late crimson-flowered and late white-flowered. 



517. Seeding. The rate of seeding varies from 12 

 to 20 pounds to an acre, 15 pounds being the usual rate. 

 One pound contains about 120,000 seeds, so that at the 

 ordinary rate 45 seeds to the square foot are sown. In 

 Europe the rate of seeding seems to be much higher, as 

 Werner recommends 22 to 40 pounds if broadcasted, and 

 18 to 26 pounds if drilled. 



Crimson clover is sown either by broadcasting or by 

 drilling. Shallow seeding seems to be most satisfactory, 

 but no critical experiments have been recorded. One 

 inch depth in sandy soil and one-half inch in clay soils is 

 probably a good general rule. 



Home-grown seed in the hull is often sown by farmers, 

 and the belief prevails that such seed is more likely to give 

 a good stand than the hulled seed.
