Qualidade dos frutos e produtividade do maracujazeiro amarelo cultivado sob diferentes lâminas de irrigação

Abstract

The yellow passion fruit tree (Passiflora edulis) is a fruit tree belonging to the Passifloraceae family. Brazil is one of the world's largest producers and consumers of the fruit. Irrigation is directly important for productivity and drip irrigation is the most appropriate method used by passiculture farmers. Correct irrigation management directly influences the success of the crop. The objective of this work was to evaluate the effect of different localized irrigation depths on: fruit quality; physical-chemical parameters; and crop productivity. The experiment was carried out in the field, on private property. The design was in randomized blocks, with six treatments (irrigation depths) and four replications. The treatments were: T1 – Depth corresponding to the crop’s Evapotranspiration; T2, T3, T4 and T5 – Depths corresponding to 33%, 80%, 133% and 200% of the depth applied by the farmer, respectively; and T6 – Depth applied by the farmer. The following were evaluated: plant height and stem diameter; physical-chemical characteristics of fruits and productivity. The different depths applied did not affect the quality of the passion fruit, but they affected the productivity of the crop, with the highest depth corresponding to the highest productivity.
