Abstract

INTRODUCTION: Nickel (Ni) is required by crops since it is a structural component of the enzymes urease and hydrogenase, which act in assimilation of nitrogen (N) by plants. In spite of its importance, there is a lack of information in regard to use of Ni in fertilization programs for dry bean. Thus, the aim of this study was to define application rates of Ni through the soil adequate for dry bean growth.

MATERIALS AND METHODS: The experiment was carried out in a greenhouse of the Soil Science Department of the Universidade Federal de Lavras, Brazil, from December 2015 to March 2016. A randomized block statistical design was used, with three replications and a 5×2 factorial arrangement, involving five application rates of Ni (0.0, 0.25, 0.75, 1.5, and 3.0 mg dm^-3) and two cultivars of dry bean (IAC Formoso and BRS Notável). The pots contained 3 dm³ of Latossolo Vermelho soil.
