Conteúdo: 	Boron is known to play important role in the structure of cell wall, membranes, and membrane associated functions in plants. In soil, the hot water B extration method has been extensively used, however, difficulties with this procedure result in low accuracy and precision of extraction of avaible boron (B) in soil. The objetive of this study was to evaluate the yield, foliar concentration , and efficiency of B extracting solutions and the effect lf B fertilization on B uptake in banana leaves and fruits, subgroup Cavendish (AAA), cultivated in a Xanthic Ferrasol (Dystrophic Yellow Latosol), in the Amazonas State, Bazil. The experimental design was a completely randomized split plot, comprinsing four boron rates (0, 4, and 12 kg ha-1), and two harvest cycles (sub-treatments), with foru replicates. Available boron was determined with seven extractant solutions: Mehlich 1, Mehlich 3, hot water, HCI 0.1 mol L-1, HCI 5.0 mol L-1 and KCI 1.0 mol L-1. The application lf b fertilizer increased the yield and concentration of B in leaves an fruits. Hot water and KCI 1.0 mol L-1 were the most efficient extracting solutions for the determination of available B in soil. The application of 3.4 kg B ha-1 in first cycle and 1.3 kg B ha-1 in second cycle guarantees and adequate nutritional status in banana plants.
