Fusarium wilt, caused by the fungus
Fusarium oxysporum
f. sp.
cubense
(Foc), is a major disease affecting commercial banana production throughout the world, and its prevalence can be reduced by soil management, i.e., liming and fertilization. However, other species can also be the causal agent of Fusarium wilt, such as
Fusarium kalimantanense
. Foc and
F. kalimantanense
belong to the
Fusarium oxysporum
species complex (FOSC). The objective of this study was to analyze the relationship between the severity of Fusarium wilt in bananas and the growth of the banana cultivar Maçã (Silk, AAB), based on soil attributes. The experimental design was completely randomized in a 17 × 2 factorial scheme, with 17 soil samples collected from commercial areas of banana production, with five replications, either with or without inoculation of a
Fusarium kalimantanense
strain. 240 days after transplanting the seedlings the plant height, number of leaves, pseudostem diameter, leaf area, and the leaf, pseudostem, and total dry matter were measured. In addition, disease severity indexes on the leaves and rhizomes of the plants were calculated. Inoculation with FOSC reduced the biometric variables and plant dry matter when compared to non-inoculated plants. The effects of FOSC on the growth of the banana cultivar Maçã were enhanced in highly fertile soils, such as soils with higher pH, sum of base, and cation exchange capacity values and P, soil organic matter, Ca

contents.
