Therefore, the objective of this work was to evaluate the effect of potassium fertilization and irrigation on the yield and composition of the oil of jatropha seeds. The treatments consisted of four doses of potassium fertilization: 40 kg ha-1 of K2O, 80 kg ha-1 of K2O, 120 kg ha -1 of K2O, 120 kg ha-1 of K2O, 120 kg ha-1 of K2O, 120 Kg ha-1 of K2O and 160 kg ha-1 of K2O, and four irrigation slides: 0% of evaporation of the Class A tank (ECA); 40% of the RCT, 80% of the RCT; And 120% of RCT. The experimental design was in randomized blocks with subdivided plots with 4 replicates. For extraction of the oil of seeds was used the chemical method via Soxhlet and to obtain the composition of oil was used the gas chromatography. The treatments of fertilization and irrigation promoted an increase in the yield and quality of the oil of jatropha seeds. Plants fertilized with 120 kg ha-1 of K2O and irrigated with the irrigation blade of 80% of ECA obtain the best results.application/pdfAcesso AbertoBiodieselÁcidos graxosÁguaNutrição de plantasJatropha curcas biodieselFatty acidsWaterPlant nutritionJatropha curcasAGRONOMIA::CIENCIA DO SOLODissertação
