Reducing The Wheat Yield Gap Through Variety-Specific Management, A. De Oliveira Silva, A. K. Fritz, R. P. Lollato
Kansas Agricultural Experiment Station Research Reports
In Kansas, wheat yields have been nearly stagnant at approximately 40 bu/a for the past 30 years, which corresponds to a yield gap (the difference between average producer yield and yield potential) of approximately 35 bu/a relative to the state average yield potential of ~75 bu/a. Our objective was to continue investigation on the influence of varieties with different genetic and agronomic characteristics and management practices on grain yield to demonstrate that appropriate variety-specific management can help producers to achieve long-term profitability in a sustainable manner. The Kansas State University wheat variety performance tests (VPT) evaluate 35–50 varieties in more …
Wheat Variety Response To Intensive Vs. Standard Management Strategies To Narrow The Yield Gap In Kansas, A. De Oliveira Silva, A. K. Fritz, R. Lollato
Wheat Variety Response To Intensive Vs. Standard Management Strategies To Narrow The Yield Gap In Kansas, A. De Oliveira Silva, A. K. Fritz, R. Lollato
Kansas Agricultural Experiment Station Research Reports
Farmer-reported wheat grain yield in Kansas is approximately 35 bushels per acre lower than the estimated yield potential of ~75 bushels per acre. Our objective was to determine the influence of variety selection and management on grain yield to elucidate methods to decrease the wheat yield gap in Kansas. Field experiments were conducted at three locations (Ellsworth, Conway Springs and McPherson) in Kansas during the 2015-2016 growing season to evaluate variety-specific response to nitrogen (N) and foliar fungicide. At each site, 35 to 44 winter wheat varieties were evaluated under standard management practice (SM) based on current farmer’s practice of …
