Abstract

The characterization of litterfall in forest and agroforest systems is important to better understand the cycling of nutrients, however, few studies on litterfall of fruit trees, such as banana, are found. Therefore, the objective of this work was assess the production and decomposition and chemically characterize the litterfall of banana genotypes cropped in a dystrophic typical Red-Yellow Latossol, with weak A horizon, medium texture in a hypo-xerophytic Caatinga in the Southwest of Bahia, Brazil. A completely randomized experimental design was used, with twelve treatments (genotypes) and five replications. The genotypes Preciosa, Pacovan-Ken and Maravilha presented the greatest dry weight. The genotype Fhia18 showed the longest half-life of litterfall decomposition. The banana genotypes Preciosa, Maravilha and Pacovan-Ken produce the greatest contents of litterfall, and their chemical characterization shows the descending order Ca>N>Mg>K>S>P for macronutrients and Fe>Mn>B>Zn>Cu for micronutrients. The banana genotypes PV-79-34, Garantida, Pacovan, JV-42-135, Prata-Anã, Pacovan-Ken, Preciosa and Maravilha present the lowest number of days for decomposition of the litterfall accumulated.
