ABSTRACT Two tomato (Lycopersicon esculentum. Mill.) experiments were conducted for two years on a south-eastern Coastal Plain soil that has a high, fluctuating water table. In one experiment, two methods for managing microirrigation were compared to a treatment that received only rainfall by measuring marketable fruit yields for spring and fall cropping seasons. Irrigation increased yields for both seasons in the second year because of low rainfall. Measurements among seven shallow wells on the site showed no consistent differences for either water table depth or gradient between adjacent wells. Two cultivars were evaluated in the second year, primarily because frost severely damaged the tomato plants about three weeks after transplanting. In the second experiment, two excessively irrigated treatments were evaluated in an effort to induce a soft-fruit storage and shipping problem experienced by many growers in this region. Although extremely large quantities of irrigation water were applied, these symptoms were not observed in this study. There were no differences in fruit yield between the two water management treatments in either spring or fall. Fruit quality measurements showed no signiflcant differences. The * Sunny' cultivar performed better than 'Walter' during the fall season for the extremely wet soil condition. A double-crop, microirrigation management system has higher input costs but provides increased profitability for fresh-market tomato production, particularly where markets are available for both spring and fall crops.
