Abstract
Twelve soybean strains from MG V supplied by Dr . E. E. Hartwig, and four other cultivars ['Lee' (MG VI), 'Pickett 71' (MG VI) , 'Davis' (MG VI) and 'Ransom' (MG VII)] were included. 'Essex' , as susceptible, and 'Forrest' , as resistant, also were included. The experimental area was fertilized with 412 kg/ha of P2O5 and K2O and 4.0 tons/ha of calcitic lime was applied to raise the soil pH to 5.7.
