The application of vegetal wastes to soil have a beneficial effects on soil nutrient, physical conditions, biological activities and on the culture performance, the main objective of this study was to evaluate three kinds of vegetable byproducts: sugar cane bagasse, coffee chaff, and Buffel straw, regarding to the effect on the physical and chemical characteristics of custard apple (Annona squamosa L.).The experimental design used completely randomid plots with five repplications, and two plants per plot. The total fruit mass, the peel mass, the seed mass per fruit were evaluated. The pulp level of soluble solids was measured, as well as its pH. The presence of this mulching provided an increase in the fruit mass, thereby, increasing the commercial profit, as larger the fruit is, the greater the value per weight is. There was not a pH increase in the pulp, on the other hand the treatment using coffee chaff provided a greater level of soluble solids. Regarding to the other measured characteristics, no differences were found.
