The aim of this study was to evaluate the response of common bean (Phaseolus vulgaris L.) cv Princesa cultivated in Ultisol and Typic Quartzipsamment to nickel application. The experiment was carried out in a greenhouse at the Universidade Estadual do Norte Fluminense Darcy Ribeiro, Brazil, using a 5x2 factorial scheme in a randomized block design with four replicates. Each experimental unit consisted of a 5kg capacity pot with four plants. Treatments consisted of foliar applications of five Ni concentrations (0, 20, 40, 60 and 100mg x [l.sup.-1]) and two soils, a Typic Quartzipsamment and an Ultisol. Ni rates promoted toxicity symptoms in the primary leaves of the bean plants, characterized by small red brown stains that did not progress in time, not interfering on plants growth. The foliar application of Ni increased levels of this micronutrient in stems, mature leaves, young leaves and pods of 'Princesa' bean, indicating its high mobility in the plant, but did not alter the urea contents, indicating no effect on the activity of urease enzyme. The dry mass of the shoots and the levels of other nutrients were not affected by foliar application of Ni. Plants grown in Ultisol showed higher growth and higher contents of K, B and Cu in mature leaves, young leaves and twigs, and of Ca and Zn in mature leaves and branches.
