Clover is sometimes sown in wheat or rye stubble. This 

 is a frequent practice in Europe, especially if the spring- 

 sown seed fails to catch. The same method gives excel- 

 lent results in western Oregon if seeded in early September. 



435. Seeding without a nurse-crop. A stand of red 

 clover is most likely to be secured when sown alone. 

 This method is, however, seldom used unless all others 

 prove unsatisfactory, as it involves special preparation 

 of the land. In the South, such seeding must be in the 

 fall, preferably about September 1 ; otherwise crab-grass 

 and other weeds will destroy the clover. In the North, 

 the seed may be sown on a well-prepared, firm seed-bed 

 any time from early spring until fall. Late fall sowing 

 is inadvisable, as winter-killing is likely to be excessive. 

 Weeds are the principal menace to the success of spring 

 seeding, but they may be controlled to some extent by 

 occasionally clipping with the mower. 



436. Depth of planting. Clover seed should be 

 planted shallow to get the best results, in no case more 

 than an inch in clay soils and one and one-half inches 

 in sandy soils. 



At the- Wisconsin Experiment Station less than one- 

 half of the seeds germinated when covered with 1 inch 

 of compacted garden soil, and less than one-fifth when 

 covered with 2 inches. Shallow planting f to J of an inch 

 in depth gave the best results and all very similar. The 

 seeds planted f to f of an inch deep also germinated more 

 promptly than those placed on the surface or those planted 

 deeper. The longest rooted seedlings developed from the 

 seeds planted J, J and f of an inch deep. 



At the Michigan Experiment Station red clover was
