| Abstract | The objective of this work was to accomplish the nutritional diagnosis in conilon coffee crop cultivated in organic and conventional systems in the North of the Espirito Santo State to compare different limit indexes of diagnose in order to consider the lower and upper nutrient levels by use of foliar contents and the yield of 40 coffee crops under the conventional cultivation and 56 coffee crops under the organic cultivation. The calculations of the indexes were made through the method DRIS including the incorporation of the dry matter. Four indexes of diagnose were used for considering the nutrient as limiting. The nutrients that showed deficiency in the organic coffee crops were Mn, P, Fe and Cu. In the conventional coffee crop, Mn, N and P were the nutrients limiting. Lower index of absolute value will be able to identify with accuracy the nutrients as limiting. The first limit nutrient does not have its position modified when using different indices thresholds. |
