The present field experiment assesses the individual and combined effects of ethylenediurea (EDU, 200 ppm) and elevated CO2 (ECO2, 550 ppm), on two rice (Oryza sativa L.) cultivars, Sarjoo-52 and Pusa Basmati-1(PB-1) under FACE (Free Air Concentration Enrichment) facility.

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.

The sensitivity of photosynthesis to each of the environmental variables including low water availability, high temperature, is associated with the inevitable rise in atmospheric carbon dioxide. Plant growth responses to the increasing CO2 concentration will not only affect ecosystem productivity in the future, but also the magnitude of C sequestration by plants. The level of CO2 in the atmosphere is rising at an unprecedented rate.
