Sorghum (Sorghum bicolor) is the fifth most cultivated cereal in the world, has high liquidity in the market due to its nutritional and edaphoclimatic characteristics, however, because it is cultivated in marginal conditions, it presents productivity below its potential. The seed coating technique appears to optimize the cultivation of sorghum. The objective of this work was to analyze the quality of graniferous sorghum seeds coated with different filling materials and proportions of glue as a cementing material. After covering, the physical and physiological characteristics of the seeds and the initial development of plants in the greenhouse were evaluated. It was found that the coating with calcium silicate provided the best physical characteristics to the seeds with the highest adherence rates, total area, maximum and minimum diameter. The coatings with dolomitic limestone and dolomitic limestone + sand provided the best physiological performance of the seeds with the highest germination values and root dry matter. The proportion of cementitious material 3: 1 provided good results in addition to being more economical. It is concluded that the combination of the filling material and the cementing material used in the coating of graniferous sorghum seeds interferes with their physiological performance and physical aspect.
