An experiment was conducted in the experimental field in Chelopechene, Sofia, Bulgaria in 2019-2020 with tomato (Solanum lycopersicum variety "Big Beef" F1) cultivated under drip irrigation and fertigation. Two levels of irrigation (100% ETc and 60% ETc) with four fertilization levels (0, 80 %, 100 %, and 120 % of the fertilizer rate) have been served as treatment. In the phase 4-6th inflorescence, main growth parameters like plant height, stem diameter, number of leaves, number of inflorescences and number of fruits of tomato plants were measured. Analysis of variance (ANOVA) was performed to analyze the effect of irrigation and fertilization on vegetative and reproductive growth of plants. Under full irrigation, the plants have the thickest stems; they are leafier, with more inflorescences and formed more fruits than average. Of all the studied growth parameters, only for the number of inflorescences for both experimental years 2019 and 2020, a statistically proven difference was found for the influence of irrigation.
