This study presents the effects of climate on rice yield in the Punjab province of Pakistan. A correlation method was employed to examine the relationship between climate elements and rice yield from 1989 to 2018. The effects of climate on rice crop is estimated using the stepwise regression on the significant correlation elements. The analysis founds the positive relationship of rainfall and rice yield at re-plantation stage in the Central and Southern regions. The maximum temperature of re-plantation stage showed a negative relationship with rice yield in the Southern and Western regions. The minimum temperature of tillering, stem elongation and flowering stages had a negative relationship with rice yield in the Central region. The maximum temperature of flowering stage was indicated a negative relationship to rice yield in the Southern and Western regions. The stepwise regression analysis confirms a significant positive effect of rainfall to rice yield in the Southern region and a significant negative effect of maximum temperature on rice yield in the Southern and Western regions at re-plantation stage. The minimum and maximum temperatures of flowering stage negatively affects rice yield in the Central and Western regions respectively.
