Abstract

The objective of this study was to evaluate the chemical composition of Panicum maximum Jacq. fertilized with pig slurry (PS) and mineral fertilizer during the rainy season for two consecutive years. The experiment was conducted from October 2004 to March 2005 and from September 2005 to April 2006. The following treatments were used: Witness=replacement of 3.5 kg/ha of P2O5 and 18 kg/ha of K2O/t of dry matter of forage; TQ=replacement of 3.5 kg/ha of P2O5, 18 kg/ha of K2O/t of dry matter of forage and 300 kg of N/ha/year; T100=100 m3/ha/year of LPW; T150=150 m3/ha/year of LPW; T200=200 m3/ha/year of LPW. The fertilizations were parceled out by the number of cuttings accomplished every year and applied after each cut. The cuttings were accomplished every 28 days at 0.30 m of the soil. Macromineral (N, P, K, S, Ca, Mg) and microminerals(Cu, Fe, Zn e Mn) were assessed in each evaluated period. The experimental design was split-plot random blocks, constituted by the fertilization treatments and by the years of evaluation. The chemical composition was influenced by the fertilization with LPW and mineral, as well as by the years of evaluation. The use of 200 m3/ha/ano dose of DLS is recommended.
KEYWORDS: grass; minerals; organic fertilization.
