In the semiarid prairie of western Canada, there is renewed interest for including short durations (≤3 yr) of perennial forage in rotations with annual crops. However, there are producers who want to grow longer durations (≥4 yr) of perennial forages in rotational systems. Therefore, we assessed spring wheat (Triticum aestivum L.) yield, grain protein, and water use efficiency following 6 yr of either crested wheatgrass [Agropyron cristatum (L.) Gaertn.], or alfalfa (Medicago sativa L.), or wheat, and then 1 yr of fallow. Yield, water use, and water use efficiency were significantly lower in the first year of spring wheat production (2000) when the prior crop was crested wheatgrass or alfalfa than when it was wheat. In the second year (2001), which was a near record drought year, wheat yield and water use were significantly lower when the prior crop was alfalfa than when it was grass or wheat. From 2002 to 2005, there were no consistent differences in water use, water use efficiency, or yield of wheat due to the prior perennial crop. Wheat grain protein concentration was significantly higher following alfalfa compared with following crested wheatgrass or continuous spring wheat from 2000 to 2005. This effect was attributed to the higher N-supplying power of the soil following alfalfa. Soil water content below the rooting depth of most annual crops (≥120 cm depth) was reduced by the prior alfalfa crop, and there was no evidence from 2000 to 2005 that soil water recharge was occurring below the 150-cm depth. Key words: Semiarid prairie, alfalfa, grass, spring wheat, yield, protein, water use

Agronomic practices, such as planting date, seeding rate, and genotype, commonly influence hard red spring wheat (HRSW, Triticum aestivum L. emend. Thell.) production. Determining the agronomic optimum seeding rate (AOSR) of newly developed hybrids is needed as they respond to seeding rates differently from inbred cultivars. The objectives of this research were to determine the AOSR of new HRSW hybrids, how seeding rate alters their various yield components, and whether hybrids offer increased end-use quality, compared to conventional cultivars. The performance of two cultivars (inbreds) and five hybrids was evaluated in nine North Dakota environments at five seeding rates in 2019−2020. Responses to seeding rate for yield and protein yield differed among the genotypes. The AOSR ranged from 3.60 to 5.19 million seeds ha−1 and 2.22 to 3.89 million seeds ha−1 for yield and protein yield, respectively. The average AOSR for yield for the hybrids was similar to that of conventional cultivars. However, the maximum protein yield of the hybrids was achieved at 0.50 million seeds ha−1 less than that of the cultivars tested. The yield component that explained the greatest proportion of differences in yield as seeding rates varied was kernels spike−1 (r = 0.17 to 0.43). The end-use quality of the hybrids tested was not superior to that of the conventional cultivars, indicating that yield will likely be the determinant of the economic feasibility of any future released hybrids.
