Abstract

The application effects of five levels of dolomitic limestone (0 - 1,25 - 2,50 - 5,00 and 10,00 kg/ha) were studied in a Typic Haporthox soil. Liming increased sweet sorghum stems ant the highest yield was obtained when the amount of calcium and magnesium, bases in saturation and soil pH value were, respectively, 2,93 meq/100 cm³ , 59% and 5,71. It was observed and unbalanced potassium nutrition with the application of dolomitic limestone of 10 t/ha. The critical levels of Mg on the leaves +4 and +3, collected, respectively, at 45 and 83 days, were 0,19 and 0,31%. The juice quality was not alterated significatively by the dolomitic limestone doses used.
