An experiment was carried out in Remígio county, Paraiba State, Brazil from July/2013 to May/2014, in order to evaluate effects of saline water irrigation, bovine biofertilizer and potassium types on soil salinity, leaf composition in macronutrients and on production of yellow passion fruit plants cv BRS Gigante Amarelo. Treatments were distributed in randomized blocks arranged in factorial design 2 × 2 × 2, referring to electric conductivity water of 0.35 and 4.00 dS m-1 , in soil without and with bovine biofertilizer applied via water (volume of 6 L plant-1 of mixture) one day before and every 90 days after transplanting and conventional potassium chloride (KCl) and coated with organic polymers supplied monthly. The soil salinity in beginning of plants flowering, was increased of initial value of 0.36 dS m-1 to respectively 3.43 and 5.43 dS m-1 between plants irrigated with non-saline and saline water. Fertilization with coated KCl reduced the potassium contents compared to conventional KCl. Except in nitrogen and potassium plants were deficient in other macronutrients but produced in promising level since the productivity was superior the Brazilian average, Brazilian Northeast and average of the Paraíba State Brazil.
