:Climatic fluctuations—especially drought—affect agricultural activities. The consecutive occurrence of droughts in recent years has led to reduced farm yields and production instability. This study aims to analyze the impact of drought on wheat yield in Boroujen.
Method and Data:This research was conducted using a descriptive–analytical approach. The required data for calculating drought indices and wheat yield were obtained from existing databases. Statistical software was used to analyze the relationship between drought severity and wheat yield.
Findings:Comparison of the data indicated a positive and significant relationship between drought severity and reduction in wheat yield, with a correlation coefficient of r = 0.397. The coefficient of determination showed that about 16% of the variations in wheat yield can be explained by drought, highlighting its considerable role in yield instability.
Conclusion:Based on the results of the PNPI and SIAP indices, the drought condition in Boroujen during the study period demonstrated a gradual decrease in index values and a shift of the regional climate toward drier conditions. Both indices indicated severe droughts in 2008 and moderate droughts in 2010, 2016, and 2017. Statistical analyses—including Pearson correlation and multiple linear regression—confirmed a significant relationship between drought indices and wheat crop quality.
