摘要

Soil salinity and poor irrigation water quality and management are the main causes of reduced yields in tomato production. On the other hand, tomato quality parameters such as berry diameter, consistency, and soluble solids have improved, especially in the most popular local tomato hybrid (Camone). A 2-year greenhouse experiment was conducted using microlysimeters to assess induced water stress levels to measure the daily maximum evapotranspiration (ETM) in the greenhouse tomato cv. Camone. During the first year, different levels of induced water stress were imposed by applying different irrigation volumes: 80, 60 and 40% ETM. In the second year, two different irrigation levels were used (50 and 25% ETM). Irrigation timing was based on the 100% ETM treatment. Irrigation was applied following depletion of 20% of available water in the first year and 40% in the second year. The long-cycle tomato cropping system (October-June) was adopted. Irrigation treatments mostly affected fruit size and quality. Microlysimeters proved to be a reliable system of ET measurement. However, the actual ETM level was underestimated due to the development of plants in pots.
