Estado Nutricional de Maracujazeiro-Amarelo Irrigado Com Água Salina e Adubação Organomineral

Abstract

Plant nutrition is essential to improve productivity and increase fruit quality of the passion fruit. This experiment aimed to evaluate the passion fruit nutrition under different planting densities and fertilization. A complete randomized block design was adopted with three repetitions and four plants per parcel, using factorial arrangement 4 x 2, referring to bovine in soil with and without NPK. The irrigation was performed daily, with saline water (electrical conductivity= 4,0 dS m-1), using drip irrigation. The application of liquid bovine fertilizer, except for calcium, supplied properly the passion fruit plants in macronutrientes, showing higher results in the treatments with mineral fertilizer.
