          Abstract

          De forma geral a aplicação de resíduos vegetais ao solo tem efeitos benéficos sobre os nutrientes do solo, sob as suas condições físicas, sob a atividade biológica e sobre a performance das culturas. O objetivo principal deste trabalho foi avaliar, durante um ciclo produtivo, o efeito da cobertura de bagaço de cana, casca de café e palha de Buffel (Cenchrus ciliaris, L.), quanto ao seu efeito sobre características físicas e químicas do fruto da pinheira (Annona squamosa L.). O delineamento experimental foi o inteiramente casualizado, constando de cinco repetições, contendo duas plantas por parcela. Foram analisados: massa do fruto, massa da casca, massa das sementes e o número de sementes por fruto, o teor de sólidos solúveis e o pH da polpa. De modo geral, a presença da cobertura morta proporcionou incremento de massa aos frutos, o que promove aumento de receita, uma vez que, quanto maior for o fruto, melhor será seu preço. Não ocorreu aumento do pH da polpa, e o tratamento com casca de café proporcionou o maior teor de sólidos solúveis totais. Quanto às demais características, não foram encontradas diferenças.

          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.
