Abstract: The impact of enhanced atmospheric CO2 concentration (550ppm) was assessed in Open Top Chambers (OTCs) facility to identify the growth and yield parameters at different growth stages of two popular groundnut (Arachis hypogaea L.) genotypes- Dharani, K-9. The results showed significant differences between genotypes, CO2 levels and time intervals for all the characters studied. The experiments revealed that the genotype Dharani recorded higher response for seed weight, harvest index at eCO2 while K-9 recorded higher response for total biomass.This study is necessary if we are to realize the potential genotype for maximum yield in the future climate change scenario.
