Pineapple and bromelain studies

The experiment was conducted in field in the municipaly Remigio, state of the Paraiba, Brazil, to evaluate the effects of the use of saline water for irrigation, bovine biofertilizer and mulch on the chemical characteristics of the fruits of yellow passion fruit.The experimental design was completely randomized in a factorial 2 x 2 x 2, three replications and three plants per experimental unit.Study material consisted of irrigation with water is not saline (0.50 dS m -1 ) and saline (4.50 dS m -1 ), with and without application of bovine biofertilizer, with and without mulch.The use of bovine biofertilizer reduced the negative action of the salts, increasing the pH, soluble solids and vitamin C in fruits of yellow passion fruit.The veal and mulching biofertilizer did not affect the titratable acidity values in passion fruit with an increased salt content of water.The content of vitamin C in fruits did not change with the use of mulch and biofertilizer veal.The ratio soluble solids / acidity of the passion fruit was reduced with the use of organic inputs and soil cover by applying saline water for irrigation of plants.The increasing salinity of irrigation water increased the electrical conductivity of the juice, regardless of the application of fertilizer and use of mulch.
