摘要: The objective of this work was to evaluate the effect fertilization with filter cakes enriched soluble phosphate on sugarcane ratoons. experiment performed from November 2007 December 2009 at Presidente Prudente, Sao Paulo State, Brazil, in a completely randomized block design 4 x factorial arrangement, first factor consisting doses cake (0, 1, 2 and Mg ha -1 ) second phosphorus fertilizer 50, 100, 200 kg P2O5) replicates. following variables were evaluated: number tillers per meter, leaf area index, solids (oBrix), stalk sugar yield crop cycle. We found residual ratoon after applying planting furrow. initial tillering, cane benefit application best combination is dose between 1.0 2.0 mg 100 applied planting. This method obtains higher yields for
