Abstract	Through chemical analysis on the sheet, it is possible to assess the nutritional status of the plant, where the results are compared to standards (correlation between the concentration in the leaves and the development of the culture). The objective of this study was to evaluate the levels of nutrients in banana leaves under irrigation levels and potassium levels in Apodi plateau, Ceara. It was used a randomized block design with split plot arrangement with three replications. It was used five irrigation levels (in the plot): 50%, 75%, 100%, 125% and 150% of the lysimeter ETc and four doses of potassium (in the subplot): 0%, 60%, 140% and 200% of K2O (recommended by soil analysis). The variables analyzed were: N, P, K, Ca, Mg and S. Through the software "SAEG 9.0-UFV" the data were subjected to analysis of variance and then when significant by the F test at 5% probability, to the regression analysis. The water depth influenced significantly (p <0.05) in Ca and Mg, and K fertilization influenced only the contents of K, Mg and S.
