JOil tastes suc­cess in In­dia field tri­als

Power Watch India - - DISPATCHES NATIONAL -

JOil (S) Pte. Ltd., a sci­en­tific bioen­ergy crop de­vel­oper of a new gen­er­a­tion of Ja­t­ropha, is said to have achieved an av­er­age seed yield of 3.53 met­ric tonnes per hectare in the third year of its large scale In­dia field tri­als. Un­pruned, the yield will be 4.42 met­ric tonnes per hectare. Th­ese re­sults place JOil’s elite Ja­t­ropha va­ri­eties on track to de­liver a year 4 pro­jected yield of more than 4.5 met­ric tonnes per hectare. This puts JOil seedlings within reach of the tar­get yield of 5 met­ric tonnes per hectare at which point large-scale com­mer­cial vi­a­bil­ity is achieved. The tri­als were con­ducted on JO S1 and JO S2, two open-pol­li­nated JOil-de­vel­oped Ja­t­ropha va­ri­eties shown to have high uni­for­mity and pro­duc­tiv­ity over three gen­er­a­tions. JOil tri­als in In­dia are be­ing con­ducted across sites lo­cated in the south­ern part of Tamil Nadu.

Ac­cord­ing to JOil’s CTO, Dr Srini­vasan Ra­machan­dran, the in­crease in yield of the plants in the third year would have been > 4.2 met­ric tonnes per hectare with op­ti­mized spac­ing and with­out prun­ing. How­ever, in the ac­tual JOil field tri­als, rig­or­ous prun­ing was done on the plants uni­formly across lo­ca­tions in the third year to main­tain the canopy in shape, re­sult­ing in a yield of 3.53 met­ric tonnes per hectare. “The re­sults of the In­dia field tri­als take Ja­t­ropha closer to com­mer­cial vi­a­bil­ity, which we be­lieve is within two years from now, once a yield of five met­ric tonnes of seeds per hectare is achieved,” said Dr Srini­vasan.
