Abstract

A 4-year experiment, 1991 to 1994, was conducted in a field where sudden death syndrome (SDS) had previously been observed. The objective was to determine the effects of tillage, planting date, and soybean cultivar on the percentage of leaves with symptoms of SDS at R6 growth stage. The soybean cultivars Essex, Forrest, Hartwig, and Rhodes were each planted in 75-cm-wide rows in disk-till, ridge-till, and no-till plots. The planting dates were mid-May, mid-June, and late June to early July each year. Symptoms of SDS developed in 1991, 1992, and 1994 but in not 1993. There were significant year x cultivar (P = 0,0001) and tillage x planting date x cultivar (P = 0,05) interactions for the percentage of leaves with symptoms of SDS. Essex, Forrest, and Rhodes has a greater percentage of leaves with symptoms of SDS than did Hartwig in 1991 and 1994 ; differences among cultivars did not occur in 1992. The percentage of Essex, Forrest and Rhodes leaves with symptoms of SDS was greater for no-till than for eigher disk-till or ridge-till in mil-May plantings. There were no significant correlation between the percentage of leaves with SDS and yield.
