Oil yield in Jatropha varies significantly based on climate, soil fertility, irrigation, and seed variety. Tropical, semi-arid zones with well-drained soils support better yields. Some improved varieties (e.g., Jatropha curcas var. CJH) offer higher oil content and disease resistance. In poor conditions, yields drop sharply. Using certified, high-yielding seeds, along with best agronomic practices (like pruning and fertilization), greatly improves viability. Oil quality may also shift slightly, affecting biodiesel output but manageable with the GlobeCore USB plant’s adaptable processing system.
