Caracterização físico-químicas em frutos de Maracujá-Amarelo (Passiflora Edulis F. Degener) sob silício e matéria orgânica do solo.

Abstract

The use of silicon associated with organic matter is an alternative in fruit growing that is associated with the effects on growth, production and physicochemical characteristics of the fruits, aiming to meet the quality standards required for fresh consumption or processing. In this sense, an experiment was developed from December 2020 to September 2021 to evaluate the physicochemical characterization in yellow passion fruit pulp under silicon and soil organic matter. The treatments were arranged in randomized blocks, with four replications and 4 plants per plot, using a 5 × 2 factorial scheme, relative to the levels of silicon in the soil of 0.0; 40, 80, 120 and 160 g plant-1 equivalent to doses of 0, 45, 90, 135 and 180 kg ha-1 and two levels of organic matter (existing value in the soil 1.2% and raising the content to 4% ). Data were submitted to analysis of variance using the F test (p<0.05). For the silicon factor and the unfolding of the silicon interaction within organic matter, linear and polynomial polynomial regressions were used. For the isolated effect of organic matter, the F test was used (p < 0.05). For data analysis, the statistical software Sisvar version 5.6 was used. The physicochemical variables evaluated referred to longitudinal and transverse diameter, fruit, pulp, seed and peel mass, peel and pulp thickness, seedless pulp volume, number of seeds per fruit, pH and solids. soluble. The physical characteristics of the fruits were better in the treatments with the highest level of silicon applied to the soil (180 kg/ha). The pH and soluble solids of the fruits were influenced by the levels of silicon, with superiority of the treatments with the addition of organic matter to the soil. The addition of organic matter to the soil provided greater fruit mass and cross-sectional diameter. On the other hand, fruit skin thickness decreases with increasing levels of silicon to the soil without the addition of organic matter to the soil. The harvested yellow passion fruit presents physicochemical characteristics that can be accepted both in the industry and in the fresh market.
