Yields of such natural compounds in cultivated plants can be affected by several nutritional factors. To determine the effect of fertilization on biomass productivity, organ proportion and coumarin content, Mikania glomerata plants were submitted during one year to treatments with organic (humus or manure) and inorganic (different levels of nitrogen) fertilizers. Coumarin concentration was raised by organic fertilization, inorganic nutrients induced increased phytomass (stem and leaf) yield, however no fertilized plants showed enhanced leaf production.29-36engExpectorantFolk medicineGuacoMedicinal plantcoumarin derivativeexpectorant agentfertilizerplant extractbiomasscrop plantfertilizer applicationyield responseBrazilcoughingfertilizationmedicinal plantnonhumanphytochemistryplant growthtraditional medicineMikaniaMikania congestaMikania glomerataArtigo10.1300/J044v06n01_04Acesso restrito2-s2.0-0032430353
