This study aimed to evaluate the effect of biostimulant positioning on common bean cultivars in the southwestern Goiás conditions. The experiment was conducted in the municipality of Mineiros-GO. The experimental design was a randomized block in factorial 6x3, corresponding to the positioning of the Triplus® biostimulator (R5, R5 + R8 and water) in six common bean cultivars (BRS Campeiro, BRS Esteio, BRS Estilo, BRS Marfim, BRS Notavel and BRS Perola) in 4 replicates. The following productive attributes were evaluated: number of pod, number total of grains, number of commercial grains, number of non-commercial grains, mass of commercial grains, thousand grains mass. There was a significant interaction between cultivar x biostimulant as well as the factors alone. At the end of the experiment, it was concluded that the positioning of the biostimulant via foliar in the R5 phenological phase provided the highest yields for all common bean cultivars, especially BRS Estilo (43.87 sc ha-1) and BRS Notavel (43.02 sc ha-1). Biostimulant applications at stage R5 promoted the best results for number of non-commercial grains, mass of commercial grains, thousand grains mass. In the three stratifications used in the dendrogram, it was possible to form two groups of genotypes. Number total of grains, number of commercial grains and number of pod positively correlate with yield.
