Production and Post Harvest of ‘Kent’ Mango Under Different Irrigation Systems

Abstract

Facing the fruit market’s search for more efficient production systems, this research aimed to identify an arrangement of efficient irrigation systems for the productive and postharvest characteristics of ‘Kent’ mango fruits, under the conditions of the Brazilian semiarid. The research was performed in an agricultural property in the municipality of Petrolina-PE, with the soil classified in Quartzarenic Neosol. Four irrigation system arrangements were tested: a micro sprinkler below the canopy; a micro sprinkler between plants; two lateral dripper lines per row of plant; and a ring-shaped drip strip around the plant in a randomized block design with five repetitions. The productive characteristics were evaluated, such as number and average weight of fruits and productivity; and qualitative parameters (evaluated by plant quadrant): volume, density, firmness, soluble solids content and titratable acidity. A micro sprinkler between plants provided a greater number of fruits and productivity, as well as greater firmness and titratable acidity for mangoes of the South and West quadrants; these characteristics associated with the lowest soluble solids content of the pulp, at the time of harvest, was also obtained with a micro sprinkler between plants and induce a longer post harvest time to the fruits.

Fruit production and quality of ‘Paluma’ guava with nematode-tolerant rootstock irrigated in the semi-arid region

“…'Paluma' guava is one of the main crops exploited in the Sub-Middle São Francisco Valley, being mostly cultivated under localized irrigation, which, when well-managed, has promoted increments in yield (Vitti et al, 2020). However, edaphoclimatic conditions and biotic and abiotic stresses interfere with the performance of crops, affecting the production potential of each genetic material (Bhat et al, 2020;Oliveira et al, 2020;Simões et al, 2020).…”

Gas exchange and post-harvest quality of ‘Kent’ mango subjected to controlled water deficit in semi-arid region

“…The main quality attributes required by the mango consumer market are fruit size and mass, pulp firmness, peel color, soluble solids content, titratable acidity and pH (SHI et al, 2015), which are used as parameters to determine different commercial standards around the world. These parameters are closely related to gas exchange rates and photosynthetic production of mango (TAIZ et al, 2017), which in turn are responses especially to the water management of the crop (SIMÕES et al, 2020a).…”
