Interpretive Summary:

Technical Abstract: Shifting climate is creating uncertain growing conditions for agricultural production. Understanding the dynamics of agricultural systems using the framework of G x E x M (Genetics x Environment x Management) is critical to allow better adaptation to constantly changing conditions while increasing food production for a growing human population. Therefore, we investigated yield of spring wheat (Triticum aestivum L.) in a split-split experimental design in Mandan, ND in 2021 that included variety and both short-term and long-term management contrasts. The treatments included four spring wheat varieties (Glenn, Lang, Bolles, and VitPro) planted in plots that were historically managed as an integrated crop-livestock system (grazed) or as a crop-only system (non-grazed), with and without fertilizer. With historically low precipitation (181 mm) during the growing season (April-Aug) in 2021, we found significant yield differences (p < 0.0001) between spring wheat varieties, with no differences detected between treatments (p > 0.83). Varieties Bolles (390 kg ha-1) and Lang (361 kg ha-1) showed greater yield than Glenn (106 kg ha-1) and VitPro (90 kg ha-1), exemplifying the importance of considering genetic variety in our agricultural management strategies to adapt to shifting climactic conditions.
