It is the crop of double benefits because it has medicinal as well as industrial value. The seeds of Jatropha produce 30%-40% oil that will be the substitute for diesel. Railway department will use the Jatropha Oil. It is obvious that in coming days the demand of Jatropha oil will increase
and it will be a great advantage for the farmers. The Railway minister has announced in the parliament about the use of Jatropha oil in Railway department. Therefore farmers should cultivate Jatropha for the future benefits.
There are many advantages from the cultivation of Jatropha: (1) It can be planted on the useless boarders of the field. (2) Since it has to be planted in field at the distance of 2X2 Mtr. hence farmer can cultivate other crops like Ashwagandha, Sarpagandha, Safed Musli, Ginger, Turmeric etc. in the interspaces. (3) The depended plant crops like Kaunch, Karela, Kalihari, Giloy can also be taken in the interspaces. (4) Animals, cattle's like cow, buffalo, Ship, Goat, Camels neither eat nor destroys this crop. It doesn't affects by any kind of diseases also. (5) It is a multiyear crop, which produces continuously for 40-50 years. (6) The Jatropha Seeds can be stored for long time without any problem.
After 2 years from the plantation one-hectare land gives Rs. 20000/- per year and from the 4th year it gives Rs. 1,00,000/- per year till 50 years.
Method of plantation: - It can be planted by two methods: (1) Preparation of seeds in nursery and thereafter sowing of plants to the main field. (2) Sowing of cuttings in the main field from the Jatropha tree.
Prepare the plants from any one of the above methods and sow them in the main field in rainy season (July to Sept.). It requires water at this moment thus arrange to plain the land. If land is elaborate then irrigation can be done by drip method. Sow the plants in their permanent lines in field at the distance of 2 X 2 Mtr. (Line X Plant). The dimension of hole for sowing the plant must be 2'X2'X2'. Sow the plant in the hole and fill with soil and press the soil firmly. Thereafter irrigate the plants at 15-20 days interval. 2500 plants required for one-hectare land and for that purpose there would require 5 kg. Jatropha Seeds per hectare.
In the month of March cut the branches at the height of 2-3 fits so there can grow3-4 new branches from each cut branch. More branches will give more yield (Seeds). This cutting technique should be done in the earlier 5 years. After it do not cut the branches.
