With the objective of studying the effects of the application of different sources and doses of calcium silicate on the sugar-cane culture, cultivar SP80-1816, one installed an experiment in a Typic Hapludox, in an area located at the João Mendes - "JM" distillery (Sítio Vó Zirica), in the Municipal district of Perdões, in the state of Minas Gerais. A random block experimental layout was used, with four repetitions and a 3x3+1 factorial outline, three being sources of calcium silicate (Silifértil, Extrativa e Agronelli) and three being doses (150, 300 and 450 kg/ha), an additional treatment, without silicate (control), totalizing 10 treatments. The different sources and doses were applied in the planting furrow together with NPK manuring. The application of calcium silicate in the planting furrow, independently of the sources and doses used, provided an increase in the fiber level percent/cane, but didn't influence the total yield recoverable sugar (ATR) brix, pol e pureness (%) of cane plant.
