Peanut yield and disease incidence affected by tillage and variety. R.N. GALLAHER (1), J.L. MCKINNEY (1), J.L. BALDWIN (2), and B. KEMERATE (2).

Strip-till was compared to conventional tillage management to test 12 peanut varieties following a winter crop of rye (Secale cereale L.). Tillage was the main treatment and variety was the sub treatment in a split plot experimental design with six replications. Pod yield was not affected by tillage. Best varieties were ‘DP-1’, ‘Andru II’, and ‘AP-3’ with pod yields of 5850, 5620, and 5540 kg ha^-1. These yields were almost twice the Florida state average. These high yielding varieties also had the lowest incidence of Tomato Spotted Wilt virus and Late Leaf Spot diseases. Disease ratings were lowest in strip-till treatment.
