Jatropha is a champion of survival, and the plant is highly resistant to drought and pests. A palm oil tree lives for 20 years — the Jatropha plant life expectancy is about 50 years. Oil-bearing seeds are available in a small first crop during the second year of plant growth. Well maintained, 1 hectare can produce on average 2.5 tonnes of oil, which is 4 times more than soybeans and 10 times more than corn. For instance, 20 000 hectares of Jatropha plantations are the equivalent of 3 MW, which can provide electrical power to 5000 homes. However, these Jatropha statistics are derived from small-sized plantations. Contrary to soybeans and corn, sufficient data derived from large-scale Jatropha plantations are not available yet.
A country like India is well suited for mass production of Jatropha biofuel. Despite monsoons and droughts, many parts of the country have a favorable climate to grow Jatropha, there is an abundance of marginal lands, and labor costs are cheap. The Indian government has allocated about 40 million hectares of land to grow Jatropha — that would allow India to replace 20% of India’s diesel consumption in 5 years.
The optimal growing conditions for Jatropha are:
• Latitude: 30° north-300 south in a band around the equator.
• Average temperature: 20-30°C.
• Average annual rainfall: 600-2400 mm.
