Tests in Illinois and Iowa showed 
that north-south rows gave better 
legume stands than east-west rows. 
North-south rows help to give the 
seedlings a more uniform distribu- 
tion of light. In east-west rows, 
legume seedling mortality was 
higher in the sunny areas. Either 
high soil temperature at the sur- 
face or drying out of the soil mois- 
ture may have caused this loss. 
Corn row direction has had little 
influence on legume survival in 
- Wisconsin, even when interseedings 
were made at corn planting time.
