Abstract

Difference-Between-Tangerine-and-MandarinMiagava tangerine (Citrus reticulata) is an early citrus cultivar that is extensively planted worldwide including Iran. The present study was carried out to determine the best source of Mn, Zn and Fe spray of Miagava tangerine trees for realizing the maximum yield per unit area with the highest quality. This trial was operated based on a Randomized Complete Block Design (RCBD) with eight treatments including different ratios of three micronutrient sources (iron chelate, zinc chelate and Manganese chelate). The trees were sprayed at two stages with three different concentrations. The measured traits included fruit and fruit skin fresh and dry weight, acidity, vitamin C, sugar and fruit Zn, Fe and Mn content. Significant differences were found among different fertilizer sources in terms of their effect on quantitative and qualitative factors. Different treatments significantly increased fruit fresh and dry weight, Fe content, Mn content, sugar and vitamin C of fruits, so that the treatment of Zn + Fe + Mn had the highest indices of these traits in the fruits. The simple effects and interactions between fertilizer treatments were not statistically significant for skin fresh and dry weight, acidity and fruit Zn content.
