I Teacher at Rondonia Federal University. Different DRIS formulas have been proposed to improve the efficiency of the crop nutrition diagnoses. The objective of this study was to compare the nutritional diagnosis of the formulas of Beaufils , of Jones and of Elwali and Gascho , based on the degree of agreement in commercial orchards of Theobrama grandiflorum trees. Bivariate relationships between nutrition concentrations in healthy trees were used to calculate DRIS norms. DRIS indices were calculated based on the different formulas and interpreted by the Potential Fertilizer Response method, in five categories. Index terms: Theobroma grandiflorum, foliar diagnosis, fruit, nutritional status. Nevertheless, it is promising for the nutritional diagnosis of perennial crops, for which calibration tests are generally time-consuming and costly. The DRIS method has advantages over traditional methods for being based on nutritional ratios instead of average levels of each nutrient, eliminating dilution and concentration effects that are not dealt with adequately by traditional methods Wadt, In addition, variations in the ratios are considered, which allows the development of standardized indices, which are less onerous because they do not require extensive local calibration tests. The application of this method to fruit trees of different species e.
