PRODUCTIVITY OF SOME SELECTED RICE CULTIVARS UNDER ELEVATED CO2 AND HIGH TEMPERATURE CONDITION (Pages : 11 - 16)

A field experiment was conducted to evaluate the effect of elevated CO2 and high temperature on physiology, growth and productivity of some popular rice cultivars. Nine rice cultivars viz. moti, binni, khaskani, bunsha, maloti, shakkorkhora, bashful chikon, jhumur and one unknown were grown in four conditions. The growing conditions were open top chamber (OTC) with elevated CO2 (570 ±50 ppm), OTC with ambient CO2 (~360 ppm), OTC with high temperature (2o C high) and field condition. Elevated CO2 increased grain yield in all the rice cultivars due to increase in panicle number. However, there were varietal differences in response to elevated CO2 and high temperature which indicated the potential good genetic materials that would be better to adapt in future high CO2 warmer worldDownload
