The exponential growth of the world population makes it necessary to look for alternatives to increase food production. Amino acids are widely used to improve crop productivity, however, in table beet cultivation they are not widespread. Therefore, the objective of the research was to evaluate the effect of foliar application of an amino acid solution on the physiological indices and production of red beet. A randomized block experiment was designed with five treatments and six replications. Four concentrations of the amino acid solution VA1 (0.3 ml L-1), VA2 (0.6 ml L-1), VA3 (0.9 ml L-1), VA4 (1.2 ml L-1) were evaluated. 1) and a control treatment VA0 (0). The dry biomass of the plants, leaf area, growth rates, total chlorophyll content, leaf temperature, relative water content and agricultural yield were evaluated. The results showed lower growth and production when the amino acid solution was not used and a significant increase in the dry biomass of the plants when the solution was used in all its variants. Growth rates, chlorophyll content, as well as leaf temperature, were also benefited by amino acids. The highest productive efficiency was obtained with 0.6; 0.9- and 1.2-ml L-1 and the best performance response was at the 1.2 ml L-1 dose. Therefore, the foliar application of amino acids is an alternative to increase the growth and production of red beets.
