How many tons of Jatropha seeds per acre? • Assuming there is no intercropping needed, just jatropha plants, testing shows one can obtain an average of 7.5 kilograms of fruit or 3 kilograms of seeds per tree. • Therefore, 6 tons/acre. • At a minimum, several hundred acres of land needed for commercial operation.
How many liters of oil per 1,000 acres? • With an average ratio conversion of 40% from seeds into Jatropha oil, trees can produce 2,400 tons of Jatropha oil per 1,000 acres. • Applying a density rate of 0.9 kg/cm3, it is possible to obtain 2.7 Million liters of oil from 1,000 acres of land per year. • 2.646 million liters of biodiesel per 1000 acres
