Abstract
Objective: To know the nutritional status of the pineapple crop (Ananas comosus L. Merril).
Design/methodology/approach: The experiment was established in the Ejido La Esperanza of the municipality of Huimanguillo. A sample of soil and foliage (leaf D) of the pineapple crop was taken, of which three repetitions were used at random, taking 15 leaves per repetition.
Results: High concentrations of nitrogen (N), potassium (K) and magnesium (Mg) were found. And in relation to phosphorus (P), calcium (Ca), copper (Cu), Zinc (Zn) and boron (B) were low. The optimum iron (Fe) and medium manganese (Mn) contents in the plant tissue.
Limitations of the study/implications: The important limitation of this study is that the irrigation conditions were not included.
Findings / Conclusions: It was found that the soil is strongly acid and has problems of excess iron and that the concentrations of the macronutrients in the plant tissue and the micronutrients in the plant tissue are not directly related to the contents of some elements in the soil. It is necessary to make a study on the needs of each element in each of the phenological stages of the Creole pineapple crop. Although the foliar analysis gives a vision for the sustainable management of crop nutrition.
