ABSTRACT Globally, climate changes have significantly shifted the phenological phases and stages of rice, altered duration growing season negatively affected rice productivity due to flooding drought. However, in present study, positive negative impacts inter‐annual variability on crops during agro‐climatic zones Punjab for period from 1989 2018. Initially, first difference approach was applied minimise impact technological factors. Then, skewness kurtosis tests were used check normalisation data. The standardisation method normalise Pearson correlation determine significant effects variables yield. residuals formed confirm yield phases. analysis revealed that a high yields investigated western region compared southern regions. results showed heavy rainfall (flooding) years with low (2010, 2013 2016) Central region.
