dc.description.abstractCalophyllum inophylum and Madhuca indica are the two oil seed bearing tree species having highest oil content in seed 50-73 per cent and 20-50 per cent respectively, which is used for non edible purposes. Hence, these species are considered as promising species for biofuel production. But owing to its slow initial growth rate, it is difficult to raise sizeable planting materials within short duration. In this context to get better plantable, vigorous growing and sturdy seedlings within short duration in the nursery, an experiment on effect of elevated carbon dioxide concentration on seedling growth of Calophyllum inophyllum and Madhuca indica was conducted at college of Forestry, Sirsi during 2013-14. Experiment results showed that, in both the tree species, seedling grown under elevated CO2 concentration (9 Kg FYM equivalent to 768.48 ppm CO2) concentration has recorded significantly higher plant height (17.93 cm, 18.50 cm), collar diameter (4.82 mm, 4.89 mm), number of leaves (15.85, 20.87), leaf area (229.71 cm2, 233.84 cm2) in Calophyllum inophyllum and Madhuca indica respectively over control. After the exposure to elevated CO2 concentration the seedlings were kept for hardening under different shades. Significantly higher plant height (31.03 cm, 35.15 cm), collar diameter (19.08 mm, 19.88 mm), number of leaves (29.91, 33.46) were recorded in Calophyllum inophyllum and Madhuca indica seedling respectively, which were treated with CO2 concentration (9 Kg FYM equivalent to 768.48 ppm CO2) and grown under 75 percent shade, over control.en_US
