Abstract: Drought stress has become an important limiting factor for tomato growth and yield. To evaluate the effect of water stress on the productivity nine tomato genotypes were grown in a field at the Maritsa Vegetable Crops Research Institute under two watering regimes – optimum and 50% reduced. Flower number, fruit number, fruit weight and flower abortion rate were measured. The studied tomato genotypes showed different behavior in response to drought stress. A decrease of flower number, fruit number and fruit weight from 2nd to 5th trusses was observed in scarcity. Water stress reduced the flower number by 25% and fruit number by 58% compared to the control plants. The highest reduction of the fruit weight of 76.1% and 78.3% respectively was registered in the 4th and 5th trusses.
