1]Jatropha  reduce Global Warming by absorbing 2.8 tons of CO2 per
year, per acre, from Atmosphere.
2]Plant distance Of 2mX2m will give the best commercial value and the
plant poulation will be 2500/hect.
3]For making harvesting easy,it is better to keep the plant height
aroubd 2 mts.
4]The crop yield in 5th year will be 1.25 – 2.80 mt/hect in dry land
and 5.25 – 12.50 mt/hact in irrigation conditions.
5]Jatropha plants can yield 350- 375 gallons per hectare under dry land
cultivation.
