High returns from crops in draught and infertile land – Jatropha cultivation

Land is the base of farming industry where fertility of land, irrigation and sun light plays the role of tools in this industry. Farmers have lots of expenses for fertilizers as well as to solve the irrigation issues in the draught. In such conditions farmer look for subsidies from national programs and blessings on behalf of natural factors like rain.
The nonfeed stock crop ‘Jatropha’ has emerged as a sustainable solution for farmers. Jatropha is a draught resistant perennial that can age up to 50 years. It can grow in any type of soil whether sandy, gravelly or saline and thrives even on the stony soils and rocky crevices. Its seeds are toxic and therefore not suitable for feed and food, and is therefore widely accepted for biofuel cultivation. Its shrub takes 15 to 24 months to produce seeds and the plant gives seeds during 30 years. These seeds contain about 35 % of non-edible oil which can be converted into bio-diesel by the esterification process.
A variety of Jatropha tree ‘SDAUJ 1’ has 49.2 % oil and 47.8 % non-edible protein in its seeds. SDAUJ 1 has been developed in India and should give a higher oil yield and is therefore very suitable for commercial cultivation.
Normal Jatropha tree gives two harvests in one year, but hybrid verities of Jatropha are developed to give three harvests one year. The seed production of Jatropha rages from 2 tons per hectare per year to 12.5 ton per hectare per year after the shrub is over five years old. The tree of Jatropha grows up to a height of 3 meters and is well known for cultivation as live fence for agricultural fields to protect the crops in fields from damages by livestock as unpalatable to cattle and goats.
Jatropha is valued for its medicinal properties as a purgative and an antiseptic. Its oil is used in medicines for diseases like cancer, piles, snakebite, dropsy, paralysis, etc. The residue ‘press cake’ left after extraction of oil from seeds is rich content of proteins and carbohydrates which can be used as organic fertilizer. If detoxificated it is useful as animals feed where as another byproduct, bio-glycerol is used in the pharmaceutical industry and in making soap.

Special attention and precautions are needed during cultivation and utilization of Jatropha as it is highly toxic, It can cause death on consumption of just 4 of its seeds. And if the skin gets stainedby the milky sap from its bark, it may irritate for days.
