description: In the search for increased productivity in the common bean and in various other crops of economic interest, much research has been carried out using growth regulators, hormones and nutrients, especially in foliar application, with the aim of accelerating plant development, improving agronomic characteristics, andensuring better plant health and performance in the field. The application of biostimulant plant regulators with the purpose of increasing crop productivity is a still not a common practice in agriculture. The aim of this study therefore, was to evaluate the effect of the application of plant biostimulants together with a resistance inducer on the production components of the common bean. Five doses of a biostimulant (indolebutyric acid, kinetin and gibberellic acid) were used (0, 0.5, 1.0, 1.5 and 2.0 L ha-1), combined with four doses of a resistance inducer (0.5, 1.0, 2.0 and 3.0 L ha-1) in the common bean “IAC Formoso” under a no-tillage system. The experiment was carried out in Selvíria, in the State of Mato Grosso do Sul, during the 2013/14 agriculturalyear. The experimental design was of randomised blocks, in a 5x4 factorial scheme, with four replications. Production components and seed productivity were evaluated in the crop. The resistance inducer gave higher values for green matter (52.08 g plant-1) and dry matter (17.29 g plant-1) in the common bean at a dose of 2.04L ha-1 and 2.15 L ha-1 respectively. The greatest productivity (3,756 kg ha-1) was obtained with a dose of 0.78 L ha-1 of biostimulant. The use of vegetable biostimulant can be a viable alternative for increasing productivity in the common bean.Em busca do aumento da produtividade do feijoeiro e de várias outras culturas de interesse econômico, foram realizadas inúmeras pesquisas utilizando reguladores de crescimento, hormônios e nutrientes, principalmente em aplicações foliares com a finalidade de acelerar o desenvolvimento da planta,melhorar suas características agronômicas, garantir…
