Crop-climate link in the southeastern USA: A case study on oats and sorghum

Recognizing the crop and region-specific irreversible effects of climate change on agriculture is unavoidable. The Southeastern United States region (SE-US) contributes significantly to (US) economy through its diverse agricultural productivity. Climatically, this more vulnerable than rest country. This study was designed quantify effect changing climate, i.e., daily maximum temperature (Tmax), minimum (Tmin), precipitation, oats (Avena sativa L.) sorghum (Sorghum bicolor L. Moench) in SE-US. panel data approach with a fixed model applied by creating production function dataset (1980–2020) yield variables. required diagnostic tests were used statistically confirm that free multi-collinearity, unit root (non-stationarity), auto-correlation issues. results revealed asymmetric warming (Tmin increase > Tmax increase) over region. Tmin increased during growing season (OGS) (SGS). Precipitation OGS decreased SGS. average values Tmax, Tmin, Tavg (daily temperature) have shifted 1.08 °C (0.027 °C/year), 1.32 (0.033 1.20 (0.030 °C/year) 0.92 (0.023 1.12 (0.028 However, precipitation had 23.2 mm (0.58 mm/year) (decreased) −5.2 (−0.13 non-significant yields. With every 1 reduced (−5%) (−4%), respectively, whereas (+13%) (−7%), respectively. Taken together, net rise overall (−9%) while (+6%).
