LEVANTAMENTO NUTRICIONAL DOS BANANAIS DA REGIÃO NORTE DE MINAS GERAIS PELA ANÁLISE FOLIAR

The work objectified to evaluate the situation of the state nutricional of the irrigated banana tree of the Northerm of Minas Gerais, using the results of the foliar samples sent by producers, for they be analyzed in the EPAMIG/CTNM Soil and Leaf Laboratory in the year of 1.999 in a total of 1,099 samples. There were analysed the contents of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, Zn and Na. It was observed 97% of the appraised samples presented some deficiency, and 36% of macronutrients and 95% of micronutrients. The decreasing order of percentage of deficient samples in macronutrients was K = S > P > N > Mg > Ca. For the micronutrients the decreasing percentage of samples that presented deficiency was Zn > Cu > Fe > Mn > B. The Ca and Mn were the ones that they appraised in larger percentage of the samples evaluated with appropriate content of 98 and 87%, respectively. The B was the micronutrient more frequenty found in excessive content with 94% of the foliar samples. For the Na, the foliar content among 10 to 1,348 mg kg-1.
