Achievement:
• Identified 21 no. seed sources having seed oil contents >30% from various parts of H.P. out of which 9 no. seed sources have oil content >35%. Besides this also identified 15 no. plus trees having seed oil content >30% from various parts of H.P. out of which 9 no. genotypes have oil content >35%.
• Best time of sowing Jatropha seeds in lower Himalayas in nurseries was found to be last week of March where as in mid Himalayas it was first week of April. Raising of Plants in polybag size 15cm x 23cm proved to be the best option in the nursery.Irrigation after three days interval during nursery period in summer months resulted in more height and diameter values in polybag raised seedlings. Survival of seed raised plants in nursery as well as in the field was found to be better than the cutting raised plants.
• In grassland of Himalayas survival and growth is less as compared to agriculture field, Nallas and open forests. In open forests of Chir pine in mid hills Jatropha survived and adapted well to the local conditions in southern aspects. Jatropha tolerated mild forest fires in Himalayas. Emergence after fire damage was found to be encouraging but inhibit seed production in that season. In Lantana infested areas Jatropha could be established after carrying out 3 uprooting of Lantana in that area.
