Brazilian livestock production is a worldwide highlight, as the supply and harvest of food occurs through grazing, significantly reducing production costs. Strategies that make it possible to stimulate the vegetative and productive forage development have been studied, such as the induction of hormesis by application of a sublethal dose of glyphosate. Thus, the objective of this work was to verify the influence of the number of application of the subdose of the glyphosate acid equivalent (20 g ha-1) on morphological and production variables of Marandu grass. Four treatments were evaluated: single application, alternate application (two doses), successive applications (four doses) and control (without glyphosate application), in four sequential cuts. For the leaf/stem ratio, in the 4th cut, alternate application (10.92) did not differ from sequential application (12.21), with 50% of the operational investment and input (glyphosate). The leaf/stem ratio in alternate application was superior to the control, equivalent to 34.8%. For forage volumetric density, maximum values were recorded in the 4th cut, with the exception of the sequential treatment (17.31 kg cm-1 ha-1), as it affected the plant structure, providing tiller elongation, with a longer leaf sheath. The forage dry matter production characterized a deleterious effect for sequential treatment, registering minimum production in the 4th cut (551.56 kg ha-1), representing 67.58% of the experimental average. Occasional or strategic application of sublethal dose of glyphosate in Marandu grass promotes the development of basal forage buds, increasing leaf/stem ratio, volumetric density and forage production.
