Salinidade hídrica, fontes orgânicas e cálcio no crescimento, componentes produtivos, fisiologia e pós-colheita do maracujazeiro-amarelo

Abstract

The experiment was carried out in the municipality of Remígio, Paraíba, Brazil. Soil in the experimental area is an eutrophic Regolitic Neosol. Aiming to evaluate organic sources and calcium as mitigators of the salinity of irrigation water in the aspects of growth, productive components, physiology and post-harvest of yellow passion fruit. The treatments were organized in a split plot in a 2 x (2 x 2) factorial scheme, related to the electrical conductivity of the irrigation water (0.3 and 4.5 dS m-1), the main plot, and the subplots to the combinations of matter organic (bovine manure and sisal residue – Agave sisalana) and calcitic fertilization (without and 120 kg ha-1 of calcium). The results referring to the growth and productive components are found in chapter I (water salinity, organic sources and calcium in the growth and productive components of yellow passion fruit), p. 18 - 53; the physiological aspects in chapter II (Water salinity, organic sources and calcium in the physiology of yellow passion fruit), p. 54 - 94 , and post-harvest of fruits in chapter III (Water salinity, organic sources and calcium on the growth and quality of yellow passion fruit), p. 95 - 128.
