Qualidade física e química em brotos de palma de diferentes fontes e concentrações de adubação orgânica.

Abstract

The objective of this work was to evaluate the physical and physico-chemical quality of palm shoots produced with different sources and concentrations of organic fertilization. The work carried out in two stages, the first one was the production of the shoots carried out in the experimental area and the second in the Laboratory of Chemistry, Biochemistry and Food Analysis, of the Center of Science and Technology Agrifood, Federal University of Campina Grande. The sprouts were produced in pots with a capacity of 18L, using three fertilization sources (poultry manure, bovine manure and goat) and the control (soil) and four OM concentrations (5, 10, 15 and 20%) . The field experiment was conducted in a randomized block design (DBC) with three replicates per treatment. The variables of longitudinal and transverse diameter (DL and DT), thickness (PE) and fresh shoot mass (MFB) were evaluated. After 45 days the sprouts were harvested for the physical-chemical analysis, being conducted in a completely randomized design (DIC) with two replicates. The titratable acidity (AT), soluble solids (SS), pH, Vitamin C (Vit C), total carotenoids (TC) and total chlorophyll variables were evaluated. For the physical analyzes it is observed that the sources and the different concentrations did not promote increments for the analyzed variables. The pH for all sources of concentration were acidic. In relation to the soluble solids all sources had better values than the control. For vit variable C it is observed that the poultry source at 5% obtained higher concentration.
