摘要：

Substrates containing 0, 10, 20, and 40% (v/v) of urban waste compost were evaluated for the production of Jatropha (Jatropha curcas L.) seedlings in polytube containers. At 40 days after planting, growth characteristics and macro nutrient content in shoot were determined. The urban waste compost added to the substrate promoted increase in Jatropha plants growth. The maximum growth was obtained with the estimated dose of 24% of compost mixed with subsoil material. Increments in the dose of compost caused linear increase in K, Mg, and S shoot content, but N and Ca contents were reduced by dilution, as the shoot dry mass increased more than the uptake of those nutrients.
