Qualidade pós-colheita do coco (Cocos nucifera L.) anão verde produzido nas Várzeas de Sousa-PB sob diferentes turnos de rega.

Abstract

The production of irrigated green dwarf coconut in the Várzeas de Sousa-PB is very important for the economic and social development of the Region. In this way, the objective was to evaluate the post-harvest quality of the green dwarf coconut produced in the Sousa-PB floodplains under different irrigation shifts. The coconut tree presented six years of planting with spacing of 7 m between row and 7 m between plants. For the experimental planning, 50 plants were used in five blocks, each block, consisting of 20 coconuts, with different irrigation shifts. The first shift with daily irrigation, the second with irrigation every two days, the third every three days, the fourth every four days and the fifth every five days. The application of the treatments in this area began on November 25, 2016, the plants were submitted to the water stress situation due to water rationing, such conditions may have influenced the size and quality of the fruits of this first post-harvest evaluation. The coconuts were weighed individually, selected and measured in the Laboratory of Chemical Analysis, Biochemistry and Food Analysis of the Center for Food Science and Technology - CCTA. The experimental design used for the physical and physicochemical analyzes was statistically treated using ANOVA and Tukey 's test, at 5% probability, using the Assistat version 7.7 program. A factorial scheme 5 x 2 (factor 1: watering shifts (TR1, TR2, TR3, TR4, TR5) and factor 2: products (liquid albumen and solid albumen) were also used for the physical - chemical analyzes. However, for the physico-chemical characteristics in the conditions in which the analyzes were performed, there was a statistical difference for the products (liquid albumen and solid albumen). More studies on the irrigation shifts in the physical and physicochemical characteristics of the green dwarf coconut, since in the literature they are still scarce.
