Weather can greatly impact rice grain yields. Large amounts of spring precipitation and cooler-than-average spring temperatures can push rice planting to later dates, resulting in significantly reduced rice grain yields and lower monetary returns. High temperatures in the summer months can also reduce rice grain yields. This study uses fixed effects regression models to determine the impacts of precipitation and temperature on rice monetary returns for 3 different rice subregions in Eastern Arkansas (Northeast, East-Central, and Southeast). Results indicate that weather impacts rice monetary returns differently across the three subregions in Eastern Arkansas when moving south to north. April precipitation has negative and statistically significant impacts on rice monetary returns in East-Central and Northeast Arkansas, but the impact of April precipitation on rice monetary returns in Southeast Arkansas is not statistically significant. High average temperatures in July and high average minimum temperatures in August have negative and statistically significant impacts on rice monetary returns in all 3 subregions, but the magnitudes of the negative impact vary by subregion.
