ABSTRACT
The present investigation on climate change and its impact on growth of groundnut crop was conducted during kharif season of 2015-16 using Open Top Chamber (OTC’s) at Main Agricultural Research Station (MARS), University of Agricultural Sciences, Raichur, Karnataka. Four circular OTC’s at MARS, Raichur were used for the present investigations. groundnut was raised in different OTC’s having standard climate change treatment10 (IPCC, 2013). Elevated CO2 and temperature significantly influenced the plant growth parameters of groundnut at various crop stages. Groundnut grown in eCO2 (550 ppm) exhibited significantly higher plant height (16.90 cm) with maximum number of leaves (38.25 leaves/plant) and the corresponding values were significantly lower (9.28 cm plant height and 31.94 leaves/plant) in aCO2 + eTemperature (390 ppm + 2 °C). The growth indices viz., leaf area index (LAI) significantly highest (0.31) in eCO2 (550 ppm) and same was lower in aCO2 + eTemperature (390 ppm + 2 °C) treatment (0.11).
