Summary: | Amburana eearensis (Allem.) A. C. Smith is a Brazilian semiarid region native plant. It presents good quality wood, contains an active ingredient that can be used for food, perfume and medicine production and it is also a forage and a melifera plant. The responses of the studied species to organic fertilizer and mulch, inputs produced and cycled within its ecosystem are still unknown. For this, an experiment was conducted to study the behavior of seedlings in an agroforestry system intercropped with maize and beans, testing different levels of organic matter (0, 15 and 30 L of manure) with and without soil mulch. It was evaluated the plant height, stem diameter, leaf number, leaf area and the survival of plants in the field one year after planting. The performance of A. eearensis was indifferent to the use of mulch and well adapted to low soil organic matter conditions, obtaining the largest growth in the absence of organic matter. Keywords: cumaru; organic fertilization; mulching. O cumaru (Amburana eearensis (Allem.) A. C. Smith) e uma especie nativa do semiarido brasileiro que apresenta multiplas utilidades como madeira de boa qualidade e contem principio ativo que pode ser utilizado nas industrias alimenticias, de perfume e na producao de medicamentos. E, tambem, planta forrageira e melifera. As respostas do cumaru a adubacao organica e cobertura morta do solo, insumos oriundos e ciclados dentro do proprio agroecossistema, sao ainda pouco conhecidas. Para isto, um experimento foi montado visando estudar o comportamento das mudas em um sistema agroflorestal (em consorcio com milho e feijao), testando-se diferentes niveis de materia organica (0, 15 e 30 L de esterco na cova), com e sem cobertura morta no solo. Avaliou-se a altura de plantas, diametro caulinar, numero de folhas, area foliar e sobrevivencia das plantas no campo apos um ano de plantio. O cumaru, no sistema agroflorestal estudado, mostrou-se indiferente ao uso de cobertura morta e adaptado as condicoes de baixa materia organica no solo, obtendo-se o maior crescimento na ausencia de materia organica (esterco). Palavras-chave: cumaru; adubacao organica; cobertura do solo. |
