Porta-enxertos e cultivares de mangueira infuenciam o estado nutricional da planta e a fertilidade do solo

Mangifera indica belongs to the Anacardiaceae family, standing out for its potential in fruit growing, considered the sixth most produced fruit in Brazil and the most exported in the country. The high productivity of the mango crop in Brazil is due to the technology applied to the crop, as well as the implantation of orchards through seedlings resulting from the vegetative propagation of the grafting method, which brings greater development and precocity to the plants cultivated in the field, in addition to the program of fertilization that allows greater development and growth both in the seedlings and during the establishment phase of the orchard in the field. In this sense, this study was divided into 3 chapters. Chapter I evaluated the nutritional status of 'Palmer', 'Tommy Atkins', 'Kent' and 'Keitt' mango seedlings grafted on Capucho, Coquinho and Espada polyembryonic rootstocks. Chapter II evaluated the nutritional status of 'Palmer', 'Tommy Atkins', 'Kent' and 'Keitt' mangoes grafted onto polyembryonic rootstocks Capucho, Coquinho and Espada during establishment in dense cultivation in the São Francisco Valley. In Chapter III, the objective was to evaluate the soil fertility of the mango orchard in the establishment phase. The experiment was carried out in two phases, in the fruit nursery of the Campus of Agricultural Sciences of the Federal University of Vale do São Francisco (UNIVASF), in Petrolina-PE and in an experimental orchard of the fruit sector of UNIVASF. Macro, micronutrients and beneficial elements were determined with the following variables Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Zinc (Zn), Copper (Cu), Iron ( Fe), Manganes (Mn), Molybdenum (Mo), Sodium (Na) and Silicon (Si) and considering the fertility of the soil, the variables of Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium ( Mg), Zinc (Zn), Copper (Cu), Iron (Fe), Manganese (Mn), Sodium (Na), Hydrogenion Potential (pH), Electrical Conductivity (EC) Total Acidity (H+Al) and Exchangeable ...
