“…Plant components were not measured in other New Zealand trials where water stress reduced yield (e.g., Carter & Stoker 1983;Drewitt 1983). Water stress also reduced quality by increasing grain N percentage, and by accentuating the effect of disease on the amount of screenings.…”

This 4-year study was initiated to formulate a management package for producing high yields of high quality malting barley and involved large-scale trials comparing the levels and interactions of nitrogen (N), irrigation, and disease and pest control on yield and quality. One ha each of autumn and spring sown crops were sown in mid Canterbury each year. In the first 3 years, low and high levels of irrigation (flood irrigation when gravimetric soil moisture in the top 150 mm of soil fell to either 15% or 20%) and two levels of disease and pest control (curative and preventative) were compared at different levels of N fertiliser (100, 200, and 300 kg N/ha in Year 1, and 0, 50, 100, and 200 kg N/ha in Years 2 and 3). In the fourth year, four levels of disease control (nil, curative, half preventative, and preventative) were compared along with four levels of N fertiliser (0, 50, 100, and 150 kg N/ha). The treatment means from all eight trials (but only the first six trials in the instance of malt extract, ears/m 2 , and grains/ear) were then analysed together to determine the overall effect of treatments and treatment combinations.

“…Trial yields did not exceed 6 t/ha and were frequently < 4 t/ha (Carter & Stoker 1983). Although irrigation lifted yields and grain size and improved quality, whereas N fertiliser increased yields but reduced quality, yields were still not particularly high (Carter & Stoker 1983;Drewitt 1983). …”

Plant biomass can be used for multiple forms of bioenergy, and there is a very large potential supply, depending on which global assessment is most accurate in terms of land area that could be available for biomass production. The most suitable plant species must be identified before the potential biomass production in a particular region can be quantified. This in turn depends on the degree of climatic adaptation by those species. In the range of climates present in New Zealand, biomass crop growth has less restriction due to water deficit or low winter temperature than in most world regions. Biomass production for energy use in New Zealand would be best utilised as transport fuel since 70 % of the country's electricity generation is already renewable, but nearly all of its transport fossil fuel is imported. There is a good economic development case for transport biofuel production using waste streams and biomass crops. This review identified the most suitable crop species and assessed their production potential for use within the climatic range present in New Zealand. Information from published work was used as a basis for selecting appropriate crops in a 2year selection and evaluation process. Where there were knowledge gaps, the location-specific selections were further evaluated by field measurements. The data presented have superseded much of the speculative information on the suitability of species for the potential development of a biofuel industry in New Zealand.

“…1 tuber size; positive responses were reported for peaches (Prunus persica L.) as they had improved coloration and in potatoes (Solanum tuberosum L.) where the end-users desired smaller sized tubers, the C 2 yield fraction was increased (Gelly et al, 2004;Ghobadi et al, 2006;Hutton & Loveys, 2011;Kirda et al, 2007;Shahnazari et al, 2007;Stark et al, 2013;Tarkalson & King, 2017;Xie et al, 2012) While barley has drought tolerance potential, yield and quality response must be considered under consistent deficit amounts to determine their suitability to meet the needs of end-users with strict requirements (Mosaddek Ahmed et al, 2016). In small-grain cereal crops specifically, crop water stress early in crop development and around anthesis can reduce yield through a reduction in number of kernels per area and mean weight of kernels (Calderini et al, 2001;Carter & Stoker, 1985;Fischer, 1985;Pardo et al, 2022;Savin & Slafer, 1991). Grain quality parameters can be negatively impacted under water-stressed conditions particularly when stress occurs during grain fill (Qureshi & Neibling, 2009;Rogers et al, 2022;Stevens et al, 2015).…”

Deficit irrigation effects on adjunct and all‐malt barley yield and quality

Semiarid regions are reliant on irrigation to produce large-yielding and high-quality malt barley (Hordeum vulgare L.). Drought in the western United States is of concern as surface and ground water reductions are occurring that affect irrigation water availability. Implementing a seasonal water deficit compared to evapotranspiration (ET) is a potential strategy to reduce water usage if yield and quality can be maintained. Research was conducted in Aberdeen, ID, on the effects of deficit irrigation on yield, grain quality, and malt characteristics. Five genotypes were selected to represent those used for large-scale adjunct brewing and those targeted at the all-malt craft industry. Irrigation was managed at three rates (100%, 75%, and 50%) of estimated crop evapotranspiration (ET c ) using sprinkler irrigation. Total aboveground dry matter was not affected by irrigation until soft dough (Feekes 11.2). Yield was similar within a genotype with irrigation reduction from 100% ET c to 75% ET c . Averaged across genotypes, yields were 6936 kg ha −1 at 100% ET c and 6297 kg ha −1 at 75% ET c . At 75% ET c , protein remained just below the adjunct target (130 g kg −1 ) for four of five genotypes while all five exceeded the all-malt target (120 g kg −1 ). Reduced irrigation decreased malt extract and increased diastatic power, where β-glucan either did not differ or increased. Deficit irrigation is promising, particularly for adjunct brewing; however, expected changes to malting quality must be understood and genotype selection, altered fertilizer management, and/or changes to malting criteria may be needed for implementation. INTRODUCTIONBarley in the western United States is predominately tworow type produced for the end-use of malting and brewing.
