The objective of this work was to evaluate the effect of bean seed coating with different doses of silicon (Si) on their physical, physiological and sanitary attributes, as well as to determine the amount of nutrients absorbed in the seedlings. BRS Expedito beans, 2014/15 harvest, were used, with an initial germination of 82%. Being used as a source of Si, calcium and magnesium silicate powder (Agrosilício®) (Si: 10.53%; Ca: 25.00%; Mg: 7.00%; Fe: 10.20%; Cr: 4 , 48%; Mn: 1.72%; Ti: 0.69%; S: 0.52%; K: 0.35%), previously sieved, with a density of 1.30g / cm³. The treatment consisted of covering bean seeds, in the equivalent doses of 0, 45, 90, 135 and 180g Si 100kg-1 of seeds, which corresponded to 0; 427.3; 854.7; 1,282; 1.709g of the product for 100kg-1 of seeds. The increase in doses of up to 116g of Si 100kg-1 of seeds positively influences the expression of vigor, providing a superior development of seedlings, as well as an increase in the concentration of Si in the leaves and root Ca. Doses other than Si do not control pathogens associated with seeds.
