The objective of this work was to study the effects of organic conduction and the use of mulch on soil physicochemical attributes and to evaluate the use of irrigation levels and mulch in the performance of Banana ' BRS Tropical '. A randomized block design was adopted, with six treatments and four replications in a 3x2 split-plot factorial scheme. Three irrigation levels based on crop evapotranspiration (ETc) in were in the main plots: L1 (100% ETc); L2 (75% ETc) and L3 (50% ETc) and the use of mulch (with and without) on the soil, as banana residues in subplots. The effects of organic cultivation and mulch on soil physicochemical attributes were evaluated in time. During cultivation, increases in macroporosity and total soil porosity were recorded. The use of organic mulch influenced positively the availability of water, phosphorus, potassium, calcium and magnesium content, potential acidity and organic matter content. The productivity and quality of the ' BRS Tropical ' fruits were not influenced by the application of organic mulch or by the reduction of the irrigation depth in up to 50%.  aBanana  aIrrigação1 aCOELHO, E.
