Abstract

Two preplant treatments, a sorghum x sudangrass hybrid (Sudex) - rapeseed crop rotation, and a preplant compost amendment treatment, were compared to a control corn-barley rotation for alleviating replant problems on a field with a long history of perennial fruit crops. A raspberry selection trial was planted in each treatment, and raspberry growth over two seasons was monitored to evaluate the efficacy of these treatments for pre-plant bio-remediation. The growth and initial survival in the Sudex-rapeseed treatment was similar to that of the corn-barley control. However, the corn-barley-compost treatment significantly improved raspberry growth and survival. At the conclusion of the experiment root samples were assayed. Isolates of root-disease associated fast-growing fungi (Cylindrocarpon, Fusarium, Pythium, and Rhizoctonia) were found at low frequencies, but there were no significant differences in their occurrence among pre-plant treatments.
