MOREIRA, Adônis and FAGERIA, Nand Kumar. Repartition and remobilization of nutrients in banana trees. Rev. Bras. Frutic. [online]. 2009, vol.31, n.2, pp.574-581. ISSN 0100-2945. http://dx.doi.org/10.1590/S0100-29452009000200036.
The banana tree demands large quantities of fertilizers to maintain its nutritional requirements and achieve high productivity, but large percentage applied are not available, since it gets lost mainly by fixation, leaching and volatilization. The objective of this study was to evaluate the rate of remobilization and repartition of nutrients in banana tree, cultivar Thap Maeo, cultivated in the Western Amazon. The results showed that the highest proportion of K, Na, Mg, S, B, Cu, Fe and Zn was found in the pseudostem. The remaining flowers represent a strong drain of nutrients. The biomass that comes from the culture residues represents a significant source of nutrients. The nutrient remobilization index was higher with N and K. The inverse was observed with Fe and Mn.
