• Studies were carried out on the interaction between potato scab, soil pH and exchangeable calcium in two different fields, one consisting of volcanic ash soil and the other, of red-yellow soil. Severity of potato scab in the field with red-yellow soil was correlated with the soil pH, unlike in the field with volcanic ash soil. The amount of exchangeable calcium in both soils was positively correlated with the scab index of potato tuber, when the content of exchangeable calcium in soil exceeded 150 mg per 100 g soil. From these results, it was concluded that the content of exchangeable calcium is as a more reliable parameter than the soil pH to evaluate the severity of potato scab.
