The study evaluated productivity elements in tomato plants in relation to foliar fertilization. 'Beldine F1', 'Sandoline F1', 'Ciciu F1' and 'Izmir F1' tomato hybrids were grown. Foliar fertilization was done with the Bionat product. In relation to the specifics of each hybrid and the applied fertilization, the variation of some physiological and productivity parameters was recorded: plants height, Ph=179.80-203.60 ± 2.73 cm; inflorescence number, In=7.50- 8.50 ± 0.12; flower number, Fn = 5.20-6.70 ± 0.17; fecundated flower, Ff = 4.60-6.20 ± 0.20; fruit number in bunches, Fnb = 4.60-6.20 ± 0.20; average bunch weight, Abw = 0.53-0.90 ± 0.05 kg; fruits number on plant, Fnp = 35.50-50.80 ± 2.12; average fruit weight, Afw = 0.12-0.16 ± 0.01 kg; average plant production, App = 4.17-7.33 ± 0.42 kg. Based on the coefficient of variation, high variability was recorded in the case of the App parameter (CV = 20.79140) and low variability in the case of the Ph parameter (CV = 3.95331). According to PCA, the distribution diagrams of variants were generated in relation to flowering parameters (PC1 explained 80.696% of variance, and PC2 explained 18.566% of variance) and in relation to fruiting parameters (PC1 explained 83.685% of variance, and PC2 explained 15.523% of variance).
