Abstract:

The daily average concentration of carbon dioxide (CO2) in the atmosphere rose above 400 parts per million (ppm) for the first time on record in 2013, up from 280 ppm before the Industrial Revolution. The CO2 fertilization hypothesis stipulates that rising atmospheric CO2 has a positive effect on tree growth due to increasing availability of carbon. Hence, an attempt was made to understand the response of C. inophyllum seedlings to the elevated CO2 condition when they are grown in nutrient rich soils. Three month old seedlings were subjected to total nine treatments with four replication. Each replication having 20 seedlings were applied with two doses of NPK (0.5 g and 1 g per plant) and were allowed to grow under both open and elevated CO2 conditions. Seedling collar diameter increment of seedlings was negatively affected without any nutrient supplement under elevated CO2 condition. A significant increase in the total height growth of seedlings was observed under elevated CO2 condition. The elevated CO2 positively influenced the volume index of seedlings under all the and positive and higher response index value of the biomass increment to the elevated CO2 condition indicated that application of nutrients under elevated CO2 could produce seedlings with higher biomass.
