Organic Fertilization and Hydric Reposition in the Initial Production of Passiflora edullis. f. flavicarca Deg.

Abstract

The objective is to evaluate the effect of different doses of biofertilizer on initial production of seedlings of passion yellow under coefficients of organic matter and water depletion in the substrate. The study was conducted during the period from December 2016 to March 2017, in protected environment at the State University of Paraiba, Campus IV - Catole do Rocha PB. The experimental design used was completely randomized design (CRD), with factorial scheme type 5x2x2, referring to the doses of bovine biofertilizer (0; 200; 400; 600 and 800 mL) diluted in proportion of 1:1, substrate levels. S1- 70% of soil (1400 mL) + 30% bovine manure (600 mL); S2 - 30% of soil (600 mL) + 70% of bovine manure (1400 mL) and two levels of water in the soil (LAS): L1 = 100% of the available water on the substrate (AWS) and L2 = 60% of water available in the substrate, with 4 repetitions, totaling 80 experimental units. After the sowing to 110 days after the emergency (DAE) we evaluated the plant height (PH); stem diameter (SD); water consumption index (WCI); relative water content in the tissues (RWCT); dickson quality index (DQI); water use efficiency (WUE) and soil electrical conductivity (SEC). The concentration of biofertilizer about the composition of the substrate, as well as the association with water blades, that influence the initial development of the yellow passion fruits seedlings. The concentration of biofertilizer on composition of the substrate, as well as your association with blades of water influence on the initial development of the seedlings of yellow passion.
