Advanced Agronomic Practices in Wheat, Barley and Pea to Maximize Yield and Harvestability
AWC contribution: $300,000
This project will use systems thinking to identify synergies between advanced agronomic practices to maximize the profitability of Alberta growers. Using a systems approach, approximately 50 different management systems will be tested in each wheat & feed barley to maximize yields; and 15 management systems in field pea to improve harvestability. The study proposes to increase yields by 25% (up to 54 bu/acre for wheat & up to 75.5 bu/acre for barley) while maintaining pea in the rotation.
Note: this study is an expansion of the 2013 AWC funded study “Stacking Agronomic Practices to Achieve Maximum Wheat Yield (Wheat 150)
- Using a systems approach, to determine synergistic benefits of stacking multiple agronomic practices: PGRs; supplemental UAN; Agrotain; and/or foliar fungicides to increase yields and economic returns of wheat and feed barley
- To compare small plot results from objective 1 with “Wheat 150” and “Barley 180” field scale trials to develop statistical tools to allow producers to effectively analyze field research
- Determine if wheat or feed barley cultivars respond differently to the intensive agronomic practices listed in objective 1
- Using a systems approach, to determine which agronomic practices (PGRs, inter-row seeding) improve field pea harvestability
- To determine the benefits of various fungicide modes of action and application timings for use on feed barley
Benefit to producers:
This study will determine the best combination of agronomic practices for producers that ensure maximum crop productivity & profitability. In 2012, Alberta farmers harvested 7.4 million tonnes of spring wheat. The 10 yr average spring wheat yield is 42.8 bu/ac. Stacking agronomic best management practices could lead to a 25% improvement in yields (increased to 54 bu/ac). Assuming that 50% of the acres are managed with these recommendations & acres remained static, there would be a 925,000 tonne increase in Alberta spring wheat production. Based on a #1 CPS price of $146/tonne ($3.97/bu), the increased yield would be valued at $135 Million/yr in Alberta.
