| Abstract: | Biofertilizers, liquid cattle manure obtained from anaerobic processes, have emerged as an important component of the integrated nutrient supply system. Thus, an experiment was carried out from May 2002 to February 2004 to evaluate the fruit quality and macronutrient foliar contents of biofertilized yellow passion plants in Brazil. The experimental design was in randomized blocks with treatments distributed in a factorial arrangement (2?×?5) referring to two biofertilizers one simple and another enriched with macro- and micronutrients] and five doses of each biofertilizer (0.0, 0.6, 1.2, 1.8, and 2.4 L plant?1). Fruit quality and nutritional status of yellow passion fruit are affected by biofertilizer doses applied. Fruit length, width, pulp percentage, skin diameter, mass, soluble solids, and titratable acidity were improved with biofertilizer application. Simple biofertilizer promotes optimum supplies of potassium, calcium, and sulfur, while enriched biofertilizer promotes optimum supplies of nitrogen, phosphorus, potassium, and calcium. |
