This study aimed to evaluate the effect of nitrogen (N) application to the soil, alone or in combination with foliar calcium (Ca) application, on mineral content in fruits and leaves, and root growth of ?Fuyu? persimmon. The experiment was conducted in Fraiburgo, Santa Catarina, Brazil, in an orchard planted in 2007. The experiments followed a completely randomized block design with four replications per treatment. The treatments consisted of a 5x2 factorial scheme, with five N levels: 0, 50, 100, 150, and 200 kg ha-1, combined with and without foliar Ca application. N was applied as urea broadcast, split into two applications, 50% at the beginning of flowering and 50% when fruits were 2 mm in diameter. Treatments with Ca were sprayed using an electric backpack sprayer over the entire canopy of the trees (new shoots and fruit), at a spray volume equal to 500 L ha-1 at a dose of 0.3% Ca complexed with amino acids, first application at 30 days after full bloom (DAFB) and reapplication every 10 days?totaling 19 applications. Twenty-five fully ripe leaves were sampled at 100 DAFB and levels of macronutrients and micronutrients were determined. Mineral contents in twenty fruits per plot were determined in peel strips, as well as in pulp wedges without peel. Root growth was evaluated using the minirhizotron technique in soil layers of 0-0.14; 0.15-0.28; 0.29-0.42; and 0.43-0.56 m depth. The topsoil layer showed the highest number of live roots, specific surface area (SSA), and root volume. The higher the N dose, the greater the diameter, SSA, and volume of the roots. Nitrogen fertilization and foliar Ca application did not influence the mineral content in leaves, fruit peel, and pulp.
