Mineral composition of pulp and production of the yellow passion fruit with organic and conventional fertilizers.
The use of organic foods has been increased in the world. Organic fertilizers, like cattle manure, have emerged as an important component of the organic system production. The production, mass, size, and mineral composition of passion fruit pulp were evaluated when treated with a mineral fertilizer (control) (MIN) or cattle manure at a single dose equivalent to potassium fertilizer (ORG) or double dose (2×ORG). The production and the numbers of fruits of plants treated with MIN and 2×ORG was higher than with ORG. The level of nitrogen (N), phosphorus (P), zinc (Zn), iron (Fe), and copper (Cu) in the fruit pulp was similar with all three fertilizers, but the calcium (Ca) and magnesium (Mg) was higher with ORG and 2×ORG. The number and weight of the fruits of passion fruit treated with 2×ORG were similar to those with MIN fertilizer, but they contained more Ca and Mg.
