Maintaining grain quality of wheat under climate change is critical for human nutrition, end-use functional properties, as well commodity value. This paper reviews the current knowledge high temperature and elevated atmospheric CO2 on whole-grain properties wheat. It also considers utility contemporary crop models investigating impacts quality; discusses opportunities advancing model capability. Under yield can increase by up to 36%, but universally protein concentration decreases a shift in...
Incubation experiments were conducted to assess the effectiveness of N-(n-butyl) thiophosphoric triamide (NBPT) for inhibiting hydrolysis urea in three wheat-growing soils and one pasture soil south-eastern Australia, under a range temperatures (5, 15, 25°C). The NBPT decreased with increasing temperature urease activity. In acidic high activity (186 μg N/g soil.h) organic carbon content (11%), (0.1% w/w urea) had little impact on rates over all temperatures, <1% remaining at Day 14....
Four yearling crossbred wethers were used in a 4 X latin square design to compare diets varying protein solubility and amino acid profile. isonitrogenous (15% CP) with profiles resembling the of either hominy or soybean meal solubilities 13 35% formulated from common feedstuffs using linear programming methods. Water consumption, urine volume, urinary nitrogen excretion rumen ammonia butyrate concentrations higher (P<.01) for receiving rations which dietary was soluble. While apparent...
The effect of a nitrification inhibitor on nitrous oxide (N2O) emissions across seasons, the urease and fine particle spray (both targeting ammonia (NH3) loss) N2O emissions, potential for productivity benefits efficiencies by using these enhanced efficiency fertilisers (EEFs) were investigated in temperate pastures. study compared three treatments over an eight month period (April to December 2010): (1) urea (U), (2) with (3,4-dimethylpyrazole phosphate) (DMPP), (3) (N-(n-butyl)...
The effect of different nitrogen (N) management strategies (i.e. N rate; 0, 25, 50, 100 kg ha–1, split application, foliar legume precropping) were assessed for how they may reverse the reduction grain protein concentration (GPC) under elevated CO2 (eCO2; 550 µmol mol–1) wheat (cv. Yitpi) using Australian Grains Free Air Enrichment facility. GPC did not increase significantly eCO2 most when compared with ambient (aCO2; 390 mol–1). Grain yield cv. Yitpi aCO2 increased by 43% (P < 0.001)...
Abstract Background and objectives Lentil ( Lens culinaris M.) is a high‐value grain used traditionally as minimally processed product. crops are well‐suited to Mediterranean‐type climates with mild winters hot dry summers which results in the production of grain. However, extreme weather conditions, such frost, can impact lentil seed, for example, darkened seed color distorted shape resulting downgrade its market value. The quality parameters when milled wholemeal flour not reliant on...
Soil testing remains a most valuable tool for assessing the fertiliser requirement of crops. The relationship between soil tests (generally taken from surface soil) and relative yield (RY) response to is subject influence environment (e.g. water, temperature) management cultivation, sowing date). As such, degree precision often low when test calibration based on wide range independent experiments many types over years by different operators. Hence, 90% RY target used in interpretation best...
Atmospheric carbon dioxide (CO2) is predicted to reach 550 µmol mol−1 by 2050, increasing from the current ~410 concentration, and this will have an impact on wheat production grain quality. Genetic differences in response future CO2 levels, which might be exploited for higher yield sustainable quality, were investigated. Twelve diverse genotypes (11 lines 1 triticale cultivar) grown Australian Grains Free-Air Enrichment facility under ambient (~400 mol−1) elevated (eCO2) concentrations (550...
The detection and identification of traces inorganic ions sugars can play a major role in the forensic investigation an explosives related incident. This survey investigated background levels these substances general environment. Six sampling locations were selected from around mainland United Kingdom, representing urban rural sites. Swab vacuum samples collected different within each site including motor vehicles, private houses, hotels, exterior buildings, road surfaces, street signs....
Abstract The effects of elevated concentrations atmospheric CO 2 (e[CO ]) on the nutritive value wheat vegetative matter and grain as a feedstock for ruminants were investigated in study undertaken at Australian grains free‐air enrichment (AGFACE) facility. included two commercial cultivars (Janz Yitpi) genetic selections from Seri/Babex population (SB003 SB062) which had previously been characterised low high water‐soluble carbohydrate accumulation efficiency. trial was grown under ambient...
The objectives of this study were to investigate the relationship between milling yield and grain hardness. A preliminary was carried out with 20 samples (both hard soft wheats) using Brabender hardness tester (BHT) two grind settings: one‐step (0‐10) two‐step (2‐12: coarse; 0‐8: fine). correlated particle size index, single‐kernel characterization system (SKCS) hardness, break yield, reduction ( P < 0.05), whereas there no correlation method. An additional 64 ground setting further...
Storing lentil is a strategy used by growers to manage price volatility. However, studies investigating the impact of storage conditions on market and end use properties are limited. This study examined effects temperature (4, 15, 25, 35 °C) grain moisture (10 14%, w/w) traits related (seed coat colour), viability (germination capacity), (hydration capacity, milling efficiency, cooking quality) in four red cultivars (PBA Bolt, PBA Hallmark, Hurricane, Jumbo2) over 360 days. at 14% content °C...
