Zusammenfassung:The present study aimed to evaluate the physicochemical characteristics and shelf life of P. cincinnata BRS Sertao Forte fruits produced with conventional fertilization recommended for passion fruit, conventional organic fertilization, organic fertilization enriched with biotite schist, conventional fertilization with replacement of the potassium source and chemical fertilization only and the mineral nutrition of plants stored under ambient and refrigerated conditions. Analyses of pH, soluble solids, titratable acidity, ratio, color, texture and mass loss were performed. Fertilizers differed in terms of nutrient absorption associated with protein synthesis (N, S, B, Cu, Mn, Zn), especially where soil remineralizer was applied. Treatments without fertilization and that with organic fertilization enriched with biotite schist soil remineralizer also positively influenced fruit physicochemical properties such as color and texture. Fruits stored under refrigeration conditions showed the best results for the conservation of their qualitative characteristics. Under the conditions of the present study, it could be concluded that the postharvest life of P. cincinnata fruits stored under refrigeration at 10[degrees]C is at least 60 days. This period is 30 days under ambient conditions. Index terms: passion fruit, conservation, storage, color. O presente trabalho avaliou o efeito da adubacao convencional para o maracujazeiro, adubacao organica convencional, adubacao organica enriquecida com biotita xisto, adubacao convencional com substituicao da fonte potassica e somente adubacao quimica, na nutricao mineral da planta, na producao, nas caracteristicas fisico-quimicas e na vida util dos frutos de P cincinnata cultivar BRS Sertao Forte armazenados sob condicao ambiente e refrigerada. Determinaram-se os nutrientes minerais do solo e das folhas, o numero e a massa total de frutos, o pH, os solidos soluveis, a acidez titulavel, Ratio, a coloracao, a textura e a perda de massa. As adubacoes diferiram quanto a absorcao de nutrientes associados a sintese de proteinas (N, S, B, Cu, Mn e Zn), especialmente onde o remineralizador foi aplicado. Os tratamentos sem adubacao e o com adubacao organica enriquecida com remineralizador de solos biotita xisto tambem influenciaram positivamente nas propriedades fisico-quimicas de coloracao e de textura dos frutos. Os frutos armazenados sob condicao refrigerada apresentaram os melhores resultados de conservacao de suas caracteristicas qu
