The aim of this work was to evaluate the effect of foliar application of biostimulant based on Ascophyllum nodosum and nicotinamide on the production components and on the productivity of the bean crop. The experimental design consisted of randomized blocks in a 2x5 factorial scheme, with 4 replications. The experimental plots consisted of 5 planting lines, spaced 0.45 m apart and 5 meters long each. The treatments were formed by the presence and absence of A. nodosum in the dose of 1.0 ml L-1 and applications of solutions containing nicotinamide in the doses of 0, 100, 200, 300 and 400 mg L-1. The number of pods per plant, number of seeds per pod, mass of grains per plant, mass of one hundred grains and productivity were evaluated. The treatment with A. nodosum was 17.5% higher for bean grain productivity than the control. It was concluded that the biostimulant promoted an increase in the number of seeds per pod and productivity and nicotinamide increased all the productive components.
