hello Sir
Plantation practices:The disease free and bold seedlings of Jatropha are transplanted in rows at a spacing of 3x2 meter under irrigated condition accommodating 1666 plants/ha. On rainfed wasteland high density planting at 2 m x 2 m accommodating 2500 plants/ ha.is recommended.
Direct planting by seeds: The land is ploughed once or twice depending upon the nature of soil. In case of heavy soil deep ploughing is desirable, whereas in light soil shallow ploughing is sufficient. The 30 cm x 30 cm pits dug in the field at required spacing should be filled with a mixture of soil, FYM (2-3 kg) and fertilizer (20 g urea, 120 g single super phosphate and 16 g murate of potash.
Two seeds per pit should be dibbled at each pit with the onset of monsoon. When the seedlings are 4 weeks old weaker seedling
can be removed and the seedlings so removed can be used for gap filling.
TransplantingFour weeks healthy seedlings should be planted in the pit at required depth.
Eight to ten week old seedlings are to be planted in 30 cm x 30 cm pits dug in the field at required spacing and filled with a mixture of soil, FYM (2-3 kg.) and fertilizer (20 gm urea, 120 g single super phosphate and 16 g murate of potash).
Care after plantation:One irrigation is applied immediately after plantation, however, during dry period only life saving irrigations should be applied to the plants as and when required. Usually from second year onwards irrigation is not required unless soils are
shallow and sandy. Two irrigations in a year if applied at both the flowering period stages will enhance the yield.pit with the onset of monsoon. When the seedlings are 4 weeks old weaker seedling can be removed and the seedlings so removed can be used for gap filling.

shallow and sandy. Two irrigations in a year if applied at both the flowering period stages will enhance the yield.
The NPK in the ratio of 46:48:24 kg per ha is to be applied in split doses from second year onwards so as to obtain economic yields. Inter-culturing should be carried out whenever necessary. Annually, 3-4 weed lings may be carried out for keeping weed free field during initial growth period.
