The general pattern for optimum tomato production in a single-harvest program appears to favor a high level of soil moisture throughout the vegetative and early bloom phase, followed by a gradual drying-out to a moderate soil moisture level during the fruit development phase, and decreasing to a low level of soil moisture available during the ripening stage—subjecting the plants to a soil moisture tension of at least 5 bars in the zone of greatest root development.
