MUDAS DE MARACUJAZEIRO AMARELO (Passiflora edulis) SOB IRRIGAÇÃO COM ÁGUAS DE SALINIDADE CRESCENTE E FERTIRRIGAÇÃO COM BIOFERTILIZANTE BOVINO

Abstract

The passion fruit, in most of Brazil lives with a low-productivity farming due to lack of technology, from the nursery to the continued cultivation. In this respect, the use of liquid biofertilizer is an alternative to providing fertility and phyto protection culture. Thus, this study aimed to evaluate the use of fermented bovine liquid manure applied through irrigation water in the formation of seedlings of yellow passion fruit. The activities was developed in greenhouse environment of Agricultural Sciences Center, Federal University of Paraíba, Areia, where seedlings were grown using seeds from acquired from existing planting, after prior selection by size, fruit shape and coloring pulp. After sowing in polyethylene vessels with a capacity of 3.5 L substrate containing compound from a mixture of 2.5 L of the first material 10 cm in a non-saline Rhodic Yellow argiloarenosa texture fertigations to 15, 22, 29 and 36 days after seedling emergence, with the common bovine biofertilizer and enriched added in irrigation water, saline (4.5 dS m-1) and not saline (0.5 dS m-1). We evaluated the speed of emergence of seedlings, growth in height and stem diameter, number of leaves and leaf area, dry biomass of leaves, stems and roots and soil electrical conductivity of the saturation extract. The increase in water salinity, regardless of the type of bio-fertilizers, increased soil salinity and impaired the quality of the seedlings.
