Soybean Cyst Nematode Hatching Behavior, Aaron K. West, Sita Thapa, Nathan E. Schroeder
Soybean Cyst Nematode Hatching Behavior, Aaron K. West, Sita Thapa, Nathan E. Schroeder
PRECS student projects
The ability of soybean cyst nematodes (SCN. Heterodera glycines) to lay dormant as eggs within a cyst for up to 11 years, has made this parasite a principal target for soybean crop pest management. Research on SCN hatching will improve understanding of SCN biology will uncover new mechanisms for their control. This poster summarizes three experiments using hatching stimulants, soybean root exudate (SRE) zinc chloride, testing whether it affects post hatch development.
Determining Effects Of Heat Stress On Illinois Soybeans, Ava Alford, Charles Burroughs, Lisa Ainsworth
Determining Effects Of Heat Stress On Illinois Soybeans, Ava Alford, Charles Burroughs, Lisa Ainsworth
PRECS student projects
Rising global temperatures affect our food supply. Heat stress could negatively affect photosynthesis, plant development, and flower and pod production. The research summarized in this poster aims to better understand which physiological processes in soybeans are negatively affected by heat stress in order to identify targets for future soybean production. Using infrared heat arrays, two different cultivars of Illinois soybeans are continually heated. Throughout the experiment, data is collected on photosynthesis, leaf area index, and overall productivity of the plant. At the end of the growing season, all of the soybean plants will be harvested and their biomass will be …

Bulk grain angle of repose (AoR) is a key parameter for inventorying grain, predicting flow characteristics, and designing bins and grain handling systems. The AoR is defined for two cases, piling (dynamic) or emptying (static), and usually varies with grain type. The objective of this study was to measure piling angles of repose for corn, sorghum, barley, soybeans, oats, and hard red winter (HRW) wheat in steel and concrete bins in the United States. Angles were measured in 182 bins and 7 outdoor piles. The piling AoR for corn ranged from 15.7° to 30.2° (median of 20.4° and standard deviation …
Comparison Of Different Weed Control Technology Programs, D. E. Peterson, C. Thompson, C. L. Minihan
Comparison Of Different Weed Control Technology Programs, D. E. Peterson, C. Thompson, C. L. Minihan
Kansas Agricultural Experiment Station Research Reports
The development of glyphosate-resistant weeds has greatly complicated weed control in soybeans. Roundup Ready 2 Xtend and Liberty Link soybeans provide an alternative postemergence herbicide options for weed control in soybeans. Liberty Link and Roundup Ready 2 Xtend programs provided better overall weed control and slightly higher yields than Roundup Ready 2 Yield programs in this experiment. Yields of Roundup Ready 2 Yield soybeans were likely influenced by more weed competition and possibly crop injury from spray tank contamination by dicamba. Dicamba injury from tank contamination to Roundup Ready 2 Yield soybeans decreased with each subsequent treatment and also with …
Soybean Sudden Death Syndrome Influenced By Macronutrient Fertility On Irrigated Soybeans In A Corn/Soybean Rotation, Eric Adee, Dorivar Ruiz Diaz, C. R. Little
Soybean Sudden Death Syndrome Influenced By Macronutrient Fertility On Irrigated Soybeans In A Corn/Soybean Rotation, Eric Adee, Dorivar Ruiz Diaz, C. R. Little
Kansas Agricultural Experiment Station Research Reports
The effects of nitrogen (N), phosphorus (P), and potassium (K) fertilization on a corn/ soybean cropping sequence were evaluated from 1983 to 2016, with corn planted in odd years. There was a negative relationship between the P rate applied during the corn years and the severity of sudden death syndrome (SDS) in 2014 and 2016 soybean.

Sudden Death Syndrome And Soybean Planting Date, Eric Adee, C. R. Little, I. A. Ciampitti
Sudden Death Syndrome And Soybean Planting Date, Eric Adee, C. R. Little, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
The effect of planting date on severity of sudden death syndrome (SDS) and yield was evaluated for the second year in two studies at the Kansas River Valley experiment fields in 2016. One study was established to promote SDS and the other to minimize SDS. In both studies the severity of SDS was greatest with the earlier planting dates. The yield was greatest with the earlier planting date, except for the most susceptible variety. The severity of SDS was not as great as had been observed in previous years. There is a very positive benefit to planting in early May …
