Based on 38 replicated trials over 3 yr, Alvena, hard red spring wheat (Triticum aestivum L.) expressed significantly higher mean grain yield than the checks. It was significantly earlier maturing than AC Barrie and significantly more resistant to lodging than Katepwa. Wheat protein concentration of Alvena was similar to the mean of the checks and flour protein concentration was significantly higher than the check mean. Amylograph viscosity was significantly lower than the mean of the checks. Alvena meets the end-use quality and Canadian Grain Commission’s kernel visual distinguishability specifications of the Canada Western Red Spring wheat market class. Alvena expressed moderate resistance to prevalent races of loose smut and stem rust, intermediate resistance to prevalent races of leaf rust and common bunt, and moderate susceptibility to fusarium head blight.

AAC Castle, an awned hard red spring wheat (Triticum aestivum L.), cultivar, combines high grain yield and good agronomic characteristics with excellent resistance to leaf, stem, stripe rust, common bunt and loose smut. It also expressed tolerance to the orange wheat blossom midge. Based on 39 station years of data in the registration trials from 2014 to 2016, the grain yield of AAC Castle was about 17% higher than 5700PR but similar to the other checks. AAC Castle was significantly shorter than AAC Foray and CDC Terrain, but had similar lodging resistance and maturity. AAC Castle had higher test weight, protein concentration, falling number and flour yield than AAC Foray and CDC Terrain. AAC Castle is eligible for grade of the Canada Prairie Spring Red wheat market class.

Grant, C. A. 2014. Use of NBPT and ammonium thiosulphate as urease inhibitors with varying surface placement of urea and urea ammonium nitrate in production of hard red spring wheat under reduced tillage management. Can. J. Plant Sci. 94: 329–335. Field studies were conducted at two locations over 3 yr to evaluate the effect of surface placement of urea ammonium nitrate (UAN) and urea fertilizers, with and without the urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT) on straw and grain yield of hard red spring wheat (Triticum aestivum L.) grown under reduced tillage management. Ammonium thiosulphate (ATS) was also evaluated as a urease inhibitor with UAN. Surface sprayed applications of UAN were frequently less effective than dribble-banded UAN applications or broadcast or dribble-banded urea in increasing grain or straw yield of hard red spring wheat. Use of NBPT with the sprayed UAN increased its effectiveness, so that grain and straw yields were similar to those with urea or with surface dribble-banded UAN. Addition of NBPT to broadcast or banded urea did not increase straw or grain yield under the conditions of this study. While there was some indication that use of ATS with UAN may have had a limited effect on fertilizer efficiency, it did not increase final grain yield as compared with dribble-banded or spray UAN applied alone or with NBPT. If surface nitrogen (N) applications are used in reduced tillage systems, spray applications of UAN should be avoided in favour of dribble-band applications, or the use of urea. Alternately, NBPT may be effective in improving the efficacy of spray UAN.

AbstractOrganic producers in Minnesota and North Dakota, USA, indicated that they wanted to participate in hard red spring wheat (Triticum aestivumL. emend. Thell) variety evaluations. The objectives were to determine if a farmer–researcher developed scoring system could be used to rank wheat varieties for yield potential when grown in certified organic fields, identify views of organic producers about on-farm research, and identify the educational impact of the participatory variety evaluation process. Hard red spring wheat varieties were compared for grain yield at six locations on certified organic farms in Minnesota and North Dakota over a three-year period. A scoring system was developed and then used to identify the relative rank of adapted varieties for yield. Producers were asked to rank all varieties on a scale from 1 to 9, where 1 is lowest yield potential and 9 is highest yield potential. Producers were able to distinguish higher producing varieties as a group in 2003 and 2004. ‘Oklee’ a high yielding variety was ranked lowest in 2005. There was a significant linear relationship between producer ranking and yield (P<0.05) even though producers could not pick the highest yielding varieties consistently in the field. The producer survey showed that grain yield, protein content, wheat scab resistance, leaf disease resistance, early seedling vigor, test weight and canopy closure were traits producers valued most in a variety. Heading date, impact on succeeding crops, straw and stubble production were ranked lower. Multi-year variety evaluation on certified organic land was highly valued by the producers surveyed. From an educational perspective, the exercise was successful in that producers had to observe individual varieties carefully in order to come to a consensus producer ranking. The model of participatory research can be used for a variety of field research projects and field days.

The response of ‘Era’ (tolerant) and ‘Coteau’ (susceptible) hard red spring wheat (Triticum aestivumL.) to CGA-82725 2-propynyl ester of {2-[4- [(3,5-dichloro-2-pyridinyl)oxy] phenoxy] propanoic acid} was determined in field and greenhouse evaluations. Era wheat was most susceptible to CGA-82725 applied at early jointing through the boot stage. Coteau wheat was most susceptible at die two-leaf stage and between early jointing through spike emergence. Coteau was injured more than Era wheat as the CGA-82725 rate was increased from 0.14 to 0.28 kg ai/ha. Wheat grain yield reductions were greatest when CGA-82725 was applied at the early jointing through boot stage for both cultivars and averaged 73% of the control. Absorption and translocation of14C-CGA-82725 were similar and increased over time regardless of cultivar. Most of the absorbed14C remained in the treated leaf in both cultivars.
