Abstract

INTRODUCTION: One of the limitations of liquid inoculation with rhizobia in the planting furrow in the dry bean crop is the small number of research studies involving this type of inoculation and the establishment of application rates suitable for good performance of biological nitrogen fixation (BNF). Thus, the aims of this study were to evaluate the viability of liquid inoculation in the planting furrow in dry bean BRS Estilo and certify if the increase in the inoculation rate benefits its symbiosis with Rhizobium sp.

MATERIALS AND METHODS: A field experiment was carried out in a no-till planting system in the 2014/2015 crop season in a Latossolo Vermelho distrófico in the south of Minas Gerais, Brazil, at 986 m altitude, 21º58’S latitude and 45º20’W longitude. The experimental design was randomized blocks with three replications and eight treatments, involving five application rates of liquid inoculant in the planting furrow, seed inoculation, and two controls without inoculation, one without N and the other fertilized with 80 kg ha^-1 of mineral N.
