“…We hypothesized that the previous crop, rate of nitrogen (N) application, and applying fungicide will impact the producer net return (NR). The quality will be influenced by the previous crop, application of N fertilizer, control of leaf diseases with fungicide, seeding rate, and seeding date (McKenzie et al 2005;O'Donovan et al 2011O'Donovan et al , 2012Turkington et al 2012). Barley yield and grain protein impacts were evident two years after a pulse crop , and barley protein can be increased by late season N application (Bulman and Smith 1993).…”

“…McKenzie et al (2005) found delayed seeding resulted in lower yield but had no impact on protein and plumpness, but O'Donovan et al (2012) found delayed seeding increased grain protein. An increase in seeding rate reduced protein and plumpness, increased kernel uniformity, but reduced yield at seeding rates greater than 300 seed m −2 (McKenzie et al 2005;O'Donovan et al 2011O'Donovan et al , 2012 The impact of the previous year's crop and fungicide application on malting barley returns and risk of returns has not been evaluated. Khakbazan et al (2014) found that barley was more profitable when the crop two years prior was a pulse crop rather than wheat or canola.…”

Profitable malting barley (Hordeum vulgare L.) production systems are required to reverse the decline in area seeded to malting barley in western Canada. Systems that could increase the profitability of growing malting barley considered the previous crop, nitrogen (N) rate, and fungicide application. The net return (NR) and risk for these systems were computed from western Canada field data. Analysis of variance was used to evaluate the impact of systems on NR over 21 site-years of field data. Risk was evaluated with a stochastic simulation model. NR was higher and risk lower for malting barley when the preceding crop was field pea (Pisum sativum L.), when fungicide was applied at the flag leaf stage for leaf disease control, and when N was 50% of the recommended N rate. Therefore, malting barley should be grown on field pea stubble at a lower N rate, with fungicide applied when there are leaf diseases.Key words: malting barley, net return, risk, fungicide, nitrogen, previous crop.Résumé : On a besoin de systèmes de production rentables pour cultiver l'orge brassicole (Hordeum vulgare L.) et renverser le déclin actuel de la superficie consacrée à cette culture dans l'Ouest canadien. Parmi les moyens susceptibles d'accroître la rentabilité de l'orge brassicole figurent la culture antérieure, le taux d'application des engrais azotés (N) et l'usage de fongicides. Les auteurs ont calculé le revenu net (RN) et les risques associés à de tels systèmes à partir des données glanées sur le terrain dans l'ouest du Canada. L'analyse de la variance a permis d'évaluer l'impact de ces solutions sur le RN grâce aux données recueillies à 21 sites-années. Les risques ont été évalués au moyen d'un modèle de simulation stochastique. Le RN de l'orge brassicole est plus élevé et les risques liés à cette culture sont plus faibles quand celle-ci est précédée par la culture du pois (Pisum sativum L.), quand on applique un fongicide au stade de la feuille paniculaire pour lutter contre les maladies foliaires et quand on coupe le taux recommandé d'engrais N en deux. On devrait cultiver l'orge brassicole sur du chaume de pois en appliquant moins d'engrais N et en recourant à un fongicide là où sévissent des maladies foliaires.

“…The effect of N fertilization on GPC depends on the rate and timing of application, on the crop yield and on the variety seeded (O'Donovan et al, 2011). At very low soil N availability, N fertilization may increase yield without increasing or even slightly decreasing GPC, due to a dilution effect.…”

A b s t r a c t A r t i c l e I n f oThe objective of this study was to evaluate the effect of nitrogen fertilization and fungicide application on yield, grain protein concentration and kernel plumpness on malting barley. Eleven experiments were replicated in Buenos Aires province, Argentina, during years 2012 and 2013. Treatments were: 1. Control; 2. 80 kg N ha -1 applied at tillering; 3. treatment 2 plus a foliar application of 20 kg N ha -1 at Z38; 4. treatment 3 plus a foliar application of fungicide at Z38; and 5.treatment 4 plus a foliar application of fungicide at second detectable node. Nitrogen applied at tillering increased yields at the sites where soil N availability was below 100 kg N ha -1 , increased grain protein and decreased kernel plumpness on sites where kernel plumpness in the control plots was <75%. An extra foliar N fertilization did not affect yield or kernel plumpness, but increased grain protein concentration significantly 0.82 percentage points in 45% of the studied site-years. Fungicide application at Z38 increased yield and kernel plumpness in 2012, when high moisture conditions promoted fungal diseases. An extra fungicide application at second node stage had no consistent effect on the studied variables.

“…A survey of 52 craft breweries in 2001 found that 59% of breweries were interested in using malt that was produced locally (Processing Center, 2001). In the past 15 yr, 30 craft malthouses have opened with the goal of producing unique malts from regionally grown grains (Th omas, 2013;Frank and Meltzer, 2014; Evaluating Barley for the Emerging Craft Malting Industry in Western Washington…”

Evaluating Barley for the Emerging Craft Malting Industry in Western Washington

Craft malting companies are emerging in response to demand from the rapidly growing North American craft brewing industry, and creating a market for malting barley (Hordeum vulgare L.) in production regions considered to be of minor importance for this crop. Growing malting barley in these under‐represented areas, such as western Washington, requires identification of cultivars with suitable agronomic and quality characteristics. Twelve two‐row spring barley cultivars were evaluated for 2 yr at four western Washington locations to assess suitability for craft malt production in the region. Standard North American malting cultivars had lower yield stability than locally adapted feed cultivars. Pre‐harvest sprouting reduced falling number and germination capacity resulting in a high proportion of samples unsuitable for malt quality evaluation. Cultivars with the highest levels of resistance to pre‐harvest sprouting did not meet malt quality standards when malted according to standard micro‐malting methods. However, craft maltsters have more flexibility to alter processing conditions to produce malt from cultivars previously deemed unacceptable for large‐scale malting and brewing. Craft brewer specifications for malt are also different from large‐scale industry. The current work suggests the need to adjust the malting process to work with locally adapted cultivars while expanding regional testing and breeding programs. Demand for barley for craft malt production outside of major production regions is increasing. Standard North American malting barley cultivars are susceptible to preharvest sprouting and foliar pathogens common in nontraditional growing regions such as western Washington. To meet demand for craft breweries the emerging craft malting industry will need to find ways to work with locally adapted cultivars while expanding regional testing and breeding programs.
