We have Jatropha seeds available. There are cleaned and selected on size for planting purposes. One kg contains approximately 1500 seeds and is normally enough to plant one acre (4000 m2). When the plants start producing seeds is depending on different conditions, how much water etc. Normally after two to three years it should be possible to harvest. The seeds are sold from Arusha, we can try to organize transport for you. Please don't hesitate to contact us for further questions.
