- Abstract
Objective: to evaluate the effect of foliar applications of micronutrients on the quality of tomato fruits (Solanum lycopersicum L.) produced in aquaponics. Design/methodology/approach: the treatments were ACU, aquaponics; ACUFF1 aquaponics plus foliar fertilization 1 (in mg L-1) with 12.50 Fe, 5.83 Mn, 1.17 Zn, 1.08 B, 0.47 Cu, 0.43 Mo and ACUFF2, aquaponics plus foliar fertilization 2 (in mg L-1) 25.0 Fe, 11.67 Mn, 2.33 Zn, 2.17 B, 0.93 Cu and 0.87 Mo and conventional hydroponics, HID, with the Steiner nutrient solution. To evaluate total soluble solids (SST), titratable acidity (AT), SST / AT ratio, electrical conductivity (EC), pH and lycopene content, ripe fruits (completely red) were used. The experiment was conducted under a completely randomized design with four replications. An analysis of variance was performed using the GLM procedure and means were compared by Tukey (P≤0.05) with the SAS 9.3 program. Results: foliar applications in aquaponics did not affect SST, AT, SST / AT ratio and lycopene concentration but there was a slight difference in tomato juice pH, the AT, pH, SST / AT ratio and lycopene in aquaponics treatments showed no significant differences and only SST decreased 22.2% in ACU, 26.6% in ACUFF1 and 31.7% in ACUFF2 compared to HID. Limitations of the study/implications: the attributes of fruit quality in aquaponics systems are not affected by the application of nutrients via foliar, which indicates that this practice is not necessary under the conditions in which the experiment was developed. Findings/Conclusions: in aquaponics, foliar applications of micronutrients did not positively influence the chemical quality attributes of tomato fruits.
