Abstract

The better response of horsegram germination percentage to elevated CO₂ is a positive indication as this particular crop being thermo and photo-sensitive in nature at ambient field level. The higher concentration of CO₂ may play ameliorating role to offset the negative effects of variable temperature and relative humidity under climatic change scenario.
