The effect of powdery mildew (Blumeria graminis f. sp. tritici) on the grain yield and protein content of one susceptible, Springfield, and three moderately resistant cultivars, Fielder, AC Reed and AC Nanda, of soft white spring wheat (Triticum aestivum) was examined at two field locations near Lethbridge and Vauxhall, Alberta, in 1999 and 2000. At the start of heading, powdery mildew development was suppressed in half of the plots of each cultivar by a single spray application of the fungicide Tilt (propiconazole). Severe powdery mildew infection of the susceptible cultivar Springfield resulted in yield reductions ranging from 11.4 to 19.9%. The grain yield of the moderately resistant cultivar Fielder was significantly reduced at both sites in 1999 by 7.6–10.5% while AC Reed suffered a significant yield loss (7.6–9.1%) at Lethbridge in both years. The moderately resistant cultivar AC Nanda consistently had the lowest powdery mildew ratings and its yield was unaffected by the disease. A single fungicide application prevented disease buildup on the moderately resistant cultivars, but not on Springfield. The grain protein content of the moderately resistant cultivars was unaffected by powdery mildew, but it decreased in Springfield by 0.6–0.7%.

Grain yield of spring wheat (Triticum aestivum L.) fluctuates greatly in Western Loess Plateau of China due to limited and highly variable precipitation. Farmers in this area need a simple tool to predict spring wheat grain yield and assess yield loss risk efficiently. The objectives of this study were to establish relations between water use and grain yield of spring wheat for predicting actual yield and attainable yield (water limited yield) under conventional management practice and mulching practices. Reference data during 1993-2013 and field experiment conducted from 1987 to 2011 were used to determine water use-yield production function and boundary function for spring wheat. Probability of achieving a given spring wheat grain yield threshold is determined based on available soil water content at sowing plus expected precipitation during growing season. Single linear equation was obtained with slope of 14.6 kg ha-1 mm-1 and x intercept at 126.3 mm for spring wheat water use-yield production function with different wheat varieties under varying climatic patterns. The slopes of the boundary function were 16.2 kg ha-1 mm-1 and 19.1 kg ha-1 mm-1 under conventional management practice and mulching practices, respectively. With increase of available soil water content at sowing, the probability of achieving at least 2000 and 4000 kg ha-1 of spring wheat for actual and attainable yield increased under different agricultural management practices.

Relevance and Methods. The effect of three doses of nitrogen fertilizers (N30, N60, and N90) on the formation of a crop of vetch seeds mixed with spring wheat was studied in a field experiment in sod-podzolic sandy loam soil.Results. In average for the study years, the yield of vetch seeds under the influence of nitrogen fertilizers decreased at the dose of mineral nitrogen 30 kg/ha by 12,7% at a dose of 60 kg/ha by 26,4% at a dose of 90 kg/ha by 36,4%, and grain yield of spring wheat increased, respectively, 1,8; 2,5 and 2,9 times. A significant decrease in the yield of vetch was observed at doses of mineral nitrogen N60 and N90, the yield of wheat grain significantly increased at all doses of mineral nitrogen. Nitrogen fertilizers were most effective in drought conditions, when the symbiotic fixation of air nitrogen in the crop area was weakened. Under conditions of increased moisture, nitrogen fertilizers did not provide an increase in the grain yield of the mixture, but increased the resistance of the crop to lodging, which made the mixture more technologically adapted to harvesting.
