[...]the appropriate use of this micronutrient should be considered because, when applied in high doses, it can cause damage to plants and contamination of soil.[...]the objective of this study was to evaluate the sources and Zn doses applied to the soil to increase the concentration of this element in the edible part of carrot, without impairing plant growth and production.According to Kabata-Pendias & Mukherjee (2007), regardless of Zn dose applied in the soil, the highest concentrations are observed mainly in roots, which have low translocation to the shoot.According to Andrade (2010) and Zapelini & Zapelini (2007), the trials in which the researcher maintains the phenomena in control conditions and reduces external influences, as occurs in greenhouse and in experiments in vessels, in scientific terms, is the most accurate design.According to Institute of Medicine (2001), Zn recommendation for healthy adults is 8 mg day-1 for women and 11 mg day-1 for men.[...]the consumption of fortified 100 g Carrot (72.31 mg kg-1) would easily reach this recommendation and reduce considerably the potential for this micronutrient deficiency in the population since it corresponds to substantially all the Zn required in daily intake.
