Brief Project Summary:

Yields from soybean contests can offer an estimate of the yield potential of current cultivars in a region. Since record soybean yields were obtained by a farmer in Missouri (139 to 161 bu ac-1 in 2006, 2007, and 2010), several other states in the U.S. have crossed the 100 bu ac-1 threshold. In Kentucky, maximum contest yields have increased on average since 2002, but the highest yield reported is still below 100 bu ac-1 (98.4 bu ac-1 in 2015). Understanding what are the main limiting factors for soybean production in KY, and quantifying the environmental potential of current soybean cultivars, is critical for developing management recommendations that can increase both maximum and average...

Project Deliverables

Dr. Montserrat Salmeron program will provide two micrometeorological weather station that will monitor environmental conditions at both field experiments (total solar radiation, minimum and maximum temperature, wind speed and direction, relative humidity).

? Quantification of yield physiological traits with high intensive monitoring and destructive samplings at Lexington, KY, and to a lesser extent in Princeton, KY (timing and duration of developmental stages, rate of canopy cover, crop growth rate, individual seed growth rate, seed number, seed size, and effective seedfill duration). These traits will be used to study the relationship between environmental conditions and yield potential.
? Quantification of the rate of N accumulation in N fertilized and non-fertilized plots for a range of MG cultivars with different duration of seedfill period.
? Total irrigation water applied will be estimated for each individual treatment, allowing to calculate net economic returns for irrigated vs. rainfed conditions across MG choices.
? The net returns in the non-fertilized plots and the yield difference with the N fertilized ones will be used to calculate the pay-off value that would justify expenses in N fertilizer applications.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
