Effect of elevated CO2 and temperature on plant growth and development of bell pepper was studied under three Open Top Chambers (OTC) and one natural air and temperature condition. Maximum plant height (76.26 cm) at 50% flowering was recorded at elevated CO2 and lowest plant height (66.17 cm) was recorded under natural condition. Similar trend for plant height was found at maturity stage. Maximum pollen viability (80.81%), internode length of plants (9.01 cm), were observed under elevated CO2 condition. Both elevated temperature and CO2 concentration had significant effects on growth and development in vegetables. Overall, bell pepper responded negatively to elevated temperatures and little positively to elevated CO2 concentrations where in interaction of elevated CO2 and temperature positive effect of CO2 is reduced or offset by temperature effect.
