Cherry type tomato for processing industry, with determinate growth habit and increased soluble solids content (°Brix) is a new option to improve the quality of tomato-based food products. Six years (2010-2015) open field experiments were carried out to study the effect of different water supply on the yield, water temperature index (WTI) and dry matter content of ‘Strombolino’ F1 tomato in Gödöllő, Hungary. The experimental design was randomized block, with four replications for each treatment, with 4.2 plants m -2 with planting in May. Evaluation of fruit yield and its quality by single harvest of red ripened fruits was measured in all years, in August. Irrigation had a significant positive effect on yield and soluble solids yield, but negative on °Brix of individual fruits. Overall WTI (0.183 mm °C -1 ) was lower, than WTI of 31-year (0.2 mm °C -1 ), and higher (0.262 mm °C -1 ) in the irrigated treatments. Fitting of normal distribution in relation to WTI, the highest SSC yield was calculated at 0.224 mm °C-1 of WTI, which is a well-described average seasonal water demand of ‘Strombolino’. Fruits can reach high soluble solids content, but its potential SSC yield is maximum 4.0 t ha-1 in Hungary.
