Increased crop competitiveness may complement existing weed control methods. The objective of this research was to establish whether spring wheat (Triticum aestivum L.) genotypes with contrasting competitive abilities respond differently to weed control levels. Four sibling genotypes differing in competitive ability were grown under simulated weedy conditions and subjected to four weed control levels. The competitive genotypes were superior to the less-competitive genotypes in grain yield under weedy and partially weedy conditions.

Oligoculm and low-tillering spring wheat (Triticum aestivum L.) genotypes were compared to free-tillering cultivars in each of 3 yr. On average, oligoculms yielded 20–40 and 4–27% less than the free- and low-tillering genotype groups, respectively. Averaged over years, oligoculms produced 44% fewer tillers and headed 3 d earlier than the free-tillering genotypes. These two groups did not differ consistently in tiller mortality across years.

Dry Matter Accumulation

A 3-yr study was conducted on three Orthic Black Chernozemic soils to determine the effects of incremental N fertilization on grain yield and dry matter accumulation and distribution of six spring wheat (Triticum aestivum L.) cultivars. Urea (46–0–0) was sidebanded at seeding in 40 kg N ha−1 increments from 0 to 240 kg ha−1 in the first year and from 0 to 200 kg ha−1 in the 2 subsequent years. Nitrogen fertilization increased the grain and straw yields of all cultivars in each experiment. The predominant factor affecting the N response and harvest index of each cultivar was available moisture. At two of the three sites, 91% of the interexperiment variability in mean maximum grain yield was explained by variation in root zone moisture at seeding. Mean maximum total dry matter varied by less than 12% among cultivars, but mean maximum grain yield varied by more than 30%. Three semidwarf cultivars, HY 320, Marshall and Solar, had consistently higher grain yield and grain yield response to N than Glenlea and Katepwa, two standard height cultivars, and Len, a semidwarf. The mean maximum grain yield of HY 320 was the highest of the cultivars on test and those of Katepwa and Len the lowest. Len produced the least straw and total dry matter. The level of N fertilization at maximum grain yield varied among cultivars, sites and years. Marshall and Solar required the highest and Len the lowest N rates to achieve maximum grain yield. The year-to-year variation in rates of N fertilization needed to produce maximum grain yield on a specific soil type revealed the limitations of N fertility recommendations based on "average" amounts and temporal distribution of available moisture.Key words: Wheat (spring), N response, standard height, semidwarf, grain yield

End Use

Sadash is a soft white spring wheat (Triticum aestivum L.) that meets the end-use quality specifications of the Canada Western Soft White Spring class. Sadash is well-adapted to the wheat-growing regions of southern Alberta and southern Saskatchewan. Based on data from the Western Soft White Spring Wheat Cooperative Registration Test from 2003 to 2005, Sadash exhibited high grain yield, mid-season maturity, semi-dwarf stature with very strong straw, and good resistance to shattering. Sadash expressed resistance to the prevalent races of stem rust and powdery mildew, intermediate resistance to loose smut, moderate susceptibility to leaf rust and common bunt, and susceptibility to Fusarium head blight. Based on end-use quality analysis performed at the Grain Research Laboratory of the Canadian Grain Commission, Sadash had improved test weight over the check cultivars AC Reed and AC Phil and similar milling and baking performance.Key words: Triticum aestivum L., cultivar description, wheat (soft white spring), grain yield, quality, disease resistance

Days To Maturity

A field study was carried out to determine the effects of seed row configuration on days to maturity, water use and grain yield of spring wheat (Triticum aestivum L. ’Leader’) grown in a semiarid environment. From 1986 to 1989, Leader spring wheat was seeded at Swift Current, Saskatchewan in north-south equidistant-rows (25-cm row spacing) and paired-rows (two rows 10 cm apart with 50 cm between the centre of each paired row). Seed and fertilizer were applied at recommended rates for the Brown soil zone. There were no significant differences (P > 0.10) in grain yield, water use or days to maturity between equidistant-row and paired-row seeding. The data suggest that under the environmental conditions of the Brown soil zone paired-row seeding may have no agronomic advantage over equidistant-row seeding.Key words: Paired-row seeding, water use, grain yield, spring wheat

Moderate Resistance

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.
