Abstract
Selenium and zinc deficiency in the population represent a serious challenge to global health. Thus, agronomic biofortification is an alternative to increase nutrients in food and improve agricultural quality. This study aimed to evaluate the effects of the simultaneous application of Se and Zn on the production and quality of tomatoes. The experiment consisted of three doses of Se (0, 25, and 50 µg dm −3 ) and four doses of Zn (4, 8, 12, and 16 mg dm −3 ) in tomato plants ( Solanum lycopersicum L), in addition to a control without application of Se and Zn. The fruits were characterized according to the number of fruits per plant, fruit mass, yield, diameter, length, color, firmness, pH, total soluble solids, titratable acidity, lycopene, beta-carotene, vitamin C, total phenols, total flavonoids, and elemental composition. The supply of Se and 4 mg dm −3 Zn increased the fruit mass, contributing to a higher yield. The supply of Se and Zn increased beta-carotene, vitamin C, and total flavonoid content compared to the control. The supply of Se is essential for the enrichment of the fruit due to the low availability of the element in the soil; however, the Zn dose must be adapted to the respective purpose.
