N2 - Numerous studies have recently shown the effects of global warming on worldwide and regional precipitation and temperature patterns. Despite knowing that the spatial and temporal impact of climate variability on agricultural production on different scales is substantial, few studies have addressed the effect of climate change on crop yield. This study aimed to provide information on regional trends by evaluating ETCCDMI extreme indices based on long-term (from 1970 to 2015), multi-station (57 weather stations), daily air temperature, and precipitation observations across the state of Nebraska located in the Central Great Plains, USA. We analyzed climate variability’s spatial and temporal impact on agricultural production since agriculture is the most important economic sector for Nebraska. A predominant increase in mean maximum and minimum temperatures in Nebraska in the last four decades was observed with a nighttime warming trend. The extreme maximum temperatures and diurnal temperature range indices are environmental factors that negatively impact the rainfed crop production in Nebraska. As expected, the extreme precipitation events indices showed significant positive correlations with the rainfed crop yield. Further research is needed to evaluate the effect of extreme temperatures on plant growth at different phenological stages and its impact on productivity.
