“…Irrigation for all treatments was scheduled using AGRIMET weather data and targeted a soil moisture profile half way between field capacity and wilting point in the active crop root zone, or 50% management-allowable depletion (Qureshi & Neibling, 2009). In 2014, water was applied using an irrigation drip system spaced every two rows in each plot, and in 2017, water was applied using an aluminum pipe system with overhead sprinklers spaced every 12.8 m across each treatment.…”

Barley (Hordeum vulgare L.) ranks fourth in global cereal grain production and is an important crop for animal feed, malting, and human consumption. Identification of two-row barley germplasm with drought tolerance can increase genetic diversity and facilitate future barley breeding efforts. The present study evaluated 480 two-row spring barley accessions from the USDA National Small Grains Collection across two years of irrigated and terminal drought trials for grain yield, test weight, protein content, thousand-kernel weight, and kernel size. Twenty accessions were identified that showed stable high yield, high test weights, and low protein content across trials. An additional 10 accessions were identified with stable high yield, high test weights, and high protein across trials. Genome-wide association mapping with 6,366 single nucleotide polymorphism (SNP) markers revealed 15 drought-stable genetic loci significantly (false discovery rate-adjusted P < .05) associated with at least one agronomic trait across and within treatments. One locus, on chromosome 2H between 27.2 and 29.8 Mbp, was significantly associated with heading date, plant height, and kernel size across treatments in this study, and the PPD-H1 mutation in a previous study. Genetic loci on chromosomes 2H and 3H were significantly associated with increased test weight, and loci on chromosomes 3H and 5H were significantly associated with decreased grain protein content across treatments. Accessions and SNP markers significantly associated with agronomic trait stability across terminal drought and irrigated environments can assist with the development of drought-tolerant barley germplasm.

“…In addition, as reported by Forster (2003), irrigation applied late, near harvesting, may cause waterrelated diseases that reduce the grain quality required for malting. Qureshi and Neibling (2009) reported that the best time for the irrigation to be ceased corresponds to the crop stage of soft dough and that a late irrigation cut-off is detrimental. Thus, irrigation should be ceased few weeks before harvesting.…”

“…Thus, these specifications in grain quality create additional factors for growers to consider as they manage inputs to produce the highest quality barley for maltsters end use. Research has shown that genetics (Bertin and Gallais 2000;Gallais and Hirel 2004;Rogers, Hu, and Mikkelsen 2017) and management (Shafi et al 2011;Qureshi and Neibling 2009) have significant effects on grain yield and protein content of barley.…”

Information on the effects of phosphorus (P) and sulfur (S) applications on crop response and soil-P status of two-row malt barley (Hordeum vulgare L.) under high-input conditions are limited in alkaline soils despite widespread fertilizer-P and-S use. A field study was conducted during the 2015 and 2016 growing seasons where the barley cultivars (ABI-Voyager and Moravian 69) were grown at five rates of P (0, 37, 73, 110, and 147 kg P ha À1) and three rates of S (0, 112, 224 kg S ha À1). ABI-Voyager had significantly greater biological yield (17,023 kg ha À1) and grain yield (7433 kg ha À1) but a lower (44%) harvest index (HI) than Moravian 69 (15,037 kg ha À1 , 7168 kg ha À1 and 49%, respectively). Grain yield increased with rate of P-application until 37 kg P ha À1 where the maximum calculated yield was obtained at 98 kg P ha À1 by a quadratic model. Sulfur application had no significant effect on any of the measured crop or soil parameters. Olsen P increased linearly with greater fertilizer-P applications, indicating grain-P removal was not sufficient to reduce or retain STP concentrations at initial levels when P was applied. Crop-P uptake and soil-P response to fertilizer P applications are important, as remaining soil P is available for subsequent crop usage and may have potential negative environmental impacts. Thus, cultivar selection and appropriate fertilizer-P and S management will ensure optimal agronomic and economic returns while minimizing potentially negative environmental impacts for two-row malt barley produced in the western United States.
