dc.description.abstractInformation regarding the use of growth regulators in sunn hemp is still scarce, especially on the physiologic quality of seeds and growth seedlings. In this aspect, product knowledge and application rate stands out as relevant factors in production of quality seeds. This work aimed to evaluated the effect of the foliar application of growth regulators (mepiquat chloride, etil-trinexapac and paclobutrazol) in different rates (0; 75; 150; 225 and 300 g ha<sup>-1</sup>), on the physiological quality of seeds and growth seedlings of Crotalaria juncea cultivated in no-tillage system. The treatments were disposed in randomized complete block design in factorial scheme 3 x 5 (regulators x rates of application), with four replications. The results were submitted to the variance analysis, with the growth regulators compared by Tukey test and the rates for polynomial regression. Not if recommended the application of mepiquat chloride in sunn hemp culture by reducing the potential of seeds germination and dry biomass of seedlings. The etil-trinexapac must be applied in rate of 300 g ha<sup>-1</sup>, based on the reduction of moisture content and the electrical conductivity of seeds, the greater total length of seedlings and dry biomass of seedlings. The paclobutrazol must be applied in rate of 75 g ha<sup>-1</sup>, considering the potential and speed of seeds germination.en
