The objective of this work was to evaluate the nutritional status of the 'Prata Anã'(AAB) banana cultivated in North of Minas Gerais state using, the method of the diagnosis integrated system and recommendation (DRIS). The nutritional evaluations were performed in 168 leaf samples collected in 58 areas cultivated with irrigated banana . The Cu and Mn were the nutrients that presented deficient in larger frequencies of banana plantations and the nutrients that presented excessive content in larger frequencies of banana plantations were Ca, Mg and Mn. The N and K content were deficient in 18% and 23% of the banana plantations, respectively. The frequency of banana plantations with adequate content of N was larger in the high yielding banana population. The same frequency was verified with adequate content of K among banana plantations of high and low yiel. Fators of non-nutritional limited the banana yield of the population of low productivity.
