Abstract

Jatropha curcas, commercially important tree species used to produce biofuels, is known for its multipurpose benefits and its role in agro forestry. Present study examines the amenability of different J. curcas strains viz. DARL-1, DARL-2, CJC-18 and CJC-19 through semi hardwood cuttings treated with hormones [Indole 3 acetic acid, α- Naphthalene acetic acid and Indole 3 butyric Acid (200ppm)] .The exogenous plant hormones significantly affected the cuttings of different cultivars in early emergence of shoots, shoots number, shoot length (cm) and leaves per cutting as recorded in the study. The effectiveness was in the order IBA>NAA>IAA when applied to the cuttings. Among the different strains DARL-2 followed by DARL-1 showed better response to hormones as compared to CJC-18 and CJC-19. Over all, it was concluded that semi hardwood cuttings of DARL-2 and DARL-1 treated with IBA 200ppm can be used for the mass propagation of J. curcas under Central Western Himalayas of Uttarakhand.

Abstract

The present study was conducted in the winter season during 2010-12 at Defence Institute of Bio-Energy Research field station- Pithoragarh, Uttarakhand on Camelina sativa cv. Calena to optimize the different levels of irrigation for the large scale multiplication and production of seed for biofuel purposes. Irrigation at early seeding stage and then at preflowering stage resulted in the higher seed yield 1153.61 kg/ha which is 142% higher than control and also gave 472.202 lit/ha of Camelina oil.
