Potentiality of Jatropha curcas on large scale cultivation as a renewable biodiesel alternative

India consumes 7.8% of coal and 3.1% of the world's petroleum (26.7 la. Barrels/day) and ranks 3rd place in the coal consumption and 6th in the world in terms of energy consumption respectively. But we have only 0.8% of the fuel resources in India with which we can meet the requirement up to 22% only. Moreover the fuel resources are getting degraded with over consumption and there should be a supporting renewable alternative without which we need to face a severe threat in the nearby future (Agarwal D & Agarwal A K, 2007). To overcome this, several works are going on around the globe and even in India. In this regard, we have concentrated on the production of biodiesel from Jatropha curcas L. which is a promising substitute as it is cultivable even in waste lands (Akbar E et al, 2009) (Chaudhury D R et al, 2007). The govt. of India has identified 400,000 sq. km (98 M. Acres) of such lands in which Jatropha can be grown. A field work was conducted in Krishna District of Andhra Pradesh to confirm the consistency in the seed output by adopting new strategies. Plants are grown in different spacing and it is proved that with the increase in spacing the seed output is also increased. The work is still going on to focus the possibility in the consistency of the seed output, thus make it profitable to the cultivators by growing biodiesel farms and also making it a sustainable renewable alternative to the limited fossil fuels by meeting the India's total biodiesel requirement of 36 MMT in 2011–12, at least up to some extent.
