This work was conducted in order to evaluate the effect of QuitoMax® on the growth and yield of bean plants (Phaseolus vulgaris L.) under two irrigation regimes. For this seed of the variety of Tomeguín black beans planted in concrete channels of 2,60 m long and 0,60 m wide (1,56 m2) in two separate rows were placed 0,40 m was used a plant spacing of 0,11 cm for a total of 44 plants per channel, each treatment had three replicates. The treatments consisted of applying 100 (R100) percent ETc. (Standard evapotranspiration) and 50 (R50) percent of ETc, counting in each irrigation treatment a variant in which 200 mg ha-1 QuitoMax® were applied to the 20-25 days after sowing and a similar dose start flowering and another in which the bioestimulante was not applied. Evaluations were made stem length, stem diameter, number of leaflets, leaf area per plant, number of pods per plant, number of grains per pod and fresh mass of 100 grains, and the yield was estimated by unit area. The analysis of the results indicated first that the bean plants (Phaseolus vulgaris L.) are affected when subjected to a regime of insufficient irrigation and secondly that the two applications of QuitoMax® were able to improve the behavior of the different variables evaluated under insufficient water supply conditions.
