Effects of deficit irrigation by different soil moisture-based water potential on total soluble solids and fruit yields in fresh tomato were investigated. Amount of irrigation was saved about 11%, 25% and 41% at -20 kPa,-30 kPa and -40 kPa treatment compared to the -15 kPa treatment as a standard practice, respectively. Deficit irrigation with -30 kPa and -40 kPa treatment significantly increased total soluble solids by 11% and 24% at first truss compared to the -15 kPa treatment, with no significant loss of yield, respectively. However, deficit irrigation with -30 kPa and -40 kPa treatment significantly increased total soluble solids at second and third truss, but resulted in substantial yield loss compared to the standard practice. Total fruit yields at -30 kPa and -40 kPa treatment was decreased by 16.5% and 25.1% compared to the -15 kPa treatment. However, marketable fruits based on fruit size (150$sim$250g) was increased by 27.8% at -30 kPa treatment compared to the -15 kPa treatment.
