Resumo: |
Mangabeira (Hancornia speciosa) fruit is native to Brazil, and its fruit - mangaba - is widely used in agribusiness juices and ice creams. Given the growing demand for its fruit becomes imperative to cultivation of this species. Thus, it is necessary to develop farming technologies, which includes studies on fertilization. The work aimed to study the response to fertilization mangabeira planting with different sources and levels of phosphorus in soil type PSAMENT. The experiment was carried out in green- EMBRAPA, Aracaju, Sergipe. We studied two phosphorus sources (triple super phosphate and Gafsa rock phosphate) and five doses (0, 0.56, 1.12, 2.24 and 4.48 g P2O5 dm3). Observed photosynthesis, stomatal conductance, transpiration and internal CO 2, besides the production of dry matter and phosphorus content and accumulation in roots and shoots. It was concluded that the provision of high doses of phosphorus and high in acidity and concentration of aluminum substrate provided by the source superphosphate brought damage to plant development. The Gafsa rock phosphate was more efficient doque triple superphosphate as source of phosphorus for speciosa. |
