Conteúdo: | In order to evaluate mineral concentrations in leaves and fruits of 'Tommy Atkins' mango (Mangifera indica), grown under irrigated eonditions, in three different orehards of Rio Grande do Norte State, Brazil, samples were eollected at four phenological stages: vegetative growth, pre-f1owering, f1owering, and fruit ripening,for leaves, and at fruit ripening for fruits. Soil samples were eolleeted at 0- 20 and 20-40 em depths. Chemieal analyses showed that there were differenees in macroand mieronutrient eoneentrations in leaves among the three orehards studied. Foralmost ali maeronutrients, mainly nitrogen and potassium, the levels deereased with the evolution of plant phenologieal stages. Exeept for potassium, the highest nutrient levels were registered in plants from Mossoroense zone orehard, while the lowestlevels were registered in plants from Oriental Coast orehard. Exeept for iron, micronutrients eoneentrations in leaves varied among the orehards and developmental stages. There was a variation in mineral composition of harvested fruits at ripening stage, being potassium and calcium the nutrients at highest concentrations.
