Jatropha curcas potential in Hawai'i: Food, feed, and fuel.

摘要

Jatropha curcas (Jatropha) is considered to be a high-yielding biofuel crop suitable for the tropics, including Hawai'i, but a dearth of information exists to guide its management. Yield may vary according to a range of genetic, agronomic, and environmental factors. An investigation in Hawai'i involving three field sites (Poamoho Experiment Station, Oahu; Kula Agricultural Park, Maui; Hawai'i Pure Plant Oils Farm, Hawai'i) and one greenhouse trial showed there was considerable variability in plant growth and yield. Differences in climate, soil, planting material, and other site conditions are discussed. Comparison of the details of the four study sites demonstrates that Jatropha is responsive to agronomic inputs in a manner typical of many food crops in Hawai'i.
