The plants were grown in soil containing different organic compost doses (0, 5, 10, 20, 40 and 60 t ha-1), formed from the sewage sludge composting process and waste of urban vegetation pruning. At harvest, plants were analyzed for the concentration of nutrients, chlorophyll content, number of tillers, biomass production, essential oil content and the microbiological quality... |
