Effect of Crop Rotation by Sweet Corn on Cabbage Injury by Continuous Cropping

Abstract

We examined whether injury caused by continuous cropping of cabbage could be reduced by planting sweet corn on the Nobeyama plateau. We used 41 cultivars of cabbage in this study. It increased the weight of heads of cabbage in 10 cultivars with significant difference and decreased club root-disease of cabbage in 19 cultivars with significant difference by planting sweet corn. The effectiveness of planting sweet corn showed a varietal difference.
