The objective of this study was to evaluate the effect of liming on yield and technological characteristics common bean cultivars under no-tillage system. The study was carried out during two crop seasons, on a dystrophic Red Latosol, under rainfed conditions. Responses were assessed using a split-plot design with four replications. The main plots were represented by the common bean cultivars (Carioca, IAC Carioca Eté, Pérola, IAPAR 81 and Campeão 2) and the split plots were represented by the rates of dolomitic limestone (0; 1.8; 3.6 and 5.4 t ha-1). The cultivars differed in yield performance according to lime rates under no-tillage system. Campeão 2 had the best performance over the two years and IAPAR 81 responded linearly to the increasing lime rate on the second crop season. The interaction common bean cultivar x lime rates had an effect on the cooking time of the beans. IAPAR 81 presented an increase in cooking time as the rate of lime was increased along the two crop seasons. Pérola had the same effect, but only on the second crop season. Crude protein ranged between 210 and 230 g kg-1 and hydration ratio was close to 2. Neither protein nor hydration ratio were influenced by lime rates or cultivars.
