Résumé:
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.
