ABSTRACT: The aim of this research was to determine the effect of three organic manures
(vermicompost, simple compost, compost with gypsum) with four different levels, as
sources of fertilization, and mixed with river sand, this was used as an inert material,
on the phenolic content, antioxidant capacity and total soluble solids of bell peppers
(Capsicum annuum L.). The 12 mixtures formulated, with eight replications, were
distributed in a completely randomized design. Data were statistically analyzed by
analysis of variance and means were compared by test Tukey5%. All variables were
significantly affected (p ≤ 0.001). Fruits with highest phenolic content were
developed in the mixtures M2, M5 and M6 with 538.76, 541.54 and 565.04 mg
GAE·100 kg-1 DW, respectively. Antioxidant capacity of fruits was increased with
mixtures M2, M5, M6 and M7 with values of 934.48, 942.04, 921.69 and 924.17 μM
TEAC·g-1 DW, respectively. The soluble solids content was higher in mixtures M1
and M2 with values of 4.93 and 4.97 °Brix, respectively. It was concluded that the
variables studied were favored when applying, as sources of fertilization, mixtures of
these organic manures with river sand, which could represent a suitable alternative
for food production with quality nutraceutical.
