An experiment was undertaken to evaluate the effects of two doses of fertilizers in fertirrigation on yield and leaf mineral composition of yellow passion fruit plant cultivated in consortium with green dwarfish coconut tree grown in a Quartzarenic Neosoil in the north of the state of Rio de Janeiro. Fertilizer doses were: 1) N=161 and K=215 kg ha-1 year-1 and 2) N=322 and K=430 kg ha-1 year-1. Treatments had 12 replicates in a completely randomized design. Irrigation of the plants was made through a micro sprinkling system, with a flow of 60 liters hour-1, and 75% of Et0. The injection of the fertilizer was made through a Venturi type injector, coupled with a 1 hp pump. The experimental units consisted of 5 coconut plants and 20 passion fruit plants. Five leaf samples were taken at three month intervals. Samples were composed of 20 recently mature leaves, colecting the 5th leaf from the apex of the branch. Leaf N, P, K, Ca, Mg, S, Cl, Na, Fe, Zn, Cu, Mn and B contents were determined. Doses of applied fertilizers didn't differ in terms of yield and fruit average weight. Nitrogen and potassium fertilization doses affected only N, Ca, and Zn leaf concentrations in a few sampling times.
