Field experiments were conducted during the kharif seasons of 2009 and 2010 to study the effect of soil moisture content (SMC), transpiration rate (T) and stress degree days (SDD) on pod yield of three cultivars of groundnut sown on 3 dates at 15 days interval from onset of monsoon. The results revealed that the SMC, T and SDD significantly influenced the pod yield of groundnut. SMC and T were positively correlated while SDD was negatively correlated with the pod yield. The varietal differences in transpiration rate and SDD were non-significant.
