Kansas Agricultural Experiment Station Research Reports
Fusarium Head Blight (FHB) or head scab is a disease caused by the soil-borneFusariumfungus. The disease occurs frequently in southeast Kansas and can result in reductions in wheat yield and quality because of the mycotoxins developed by the fungus. Timely application of fungicides during the heading period of wheat is one option to reduce the fungus and control the infection rate. This study reports our research on use of fungicides to control head scab and improve wheat yield. We developed a model to predict wheat heading date. Accurate knowledge of wheat stage is the first step in developing …
Use Of A Fungicide To Reduce Stomatal Conductance For Production Of Sweet Corn Planted At Different Populations With Limited Irrigation, D. W. Sweeney, M. B. Kirkham
Use Of A Fungicide To Reduce Stomatal Conductance For Production Of Sweet Corn Planted At Different Populations With Limited Irrigation, D. W. Sweeney, M. B. Kirkham
Kansas Agricultural Experiment Station Research Reports
Sweet corn in 2018 was affected by irrigation, plant population, and a fungicide applied for stomatal control. Even though measured stomatal conductance was unaffected and no disease pressure was noted, applying fungicide at V6 more than doubled the number of harvested ears per acre and per plant, but an additional application at R1 did not increase harvested ears. Applying 1 inch of irrigation at the VT growth stage resulted in approximately 20% greater number of harvested ears per acre and ears per plant, but did not increase fresh weight. Under these dry conditions, increasing plant population tended to decrease harvested …
Integrated Wheat Management For Improved Wheat Yield And Protein In Kansas, B. R. Jaenisch, R. P. Lollato
Integrated Wheat Management For Improved Wheat Yield And Protein In Kansas, B. R. Jaenisch, R. P. Lollato
Kansas Agricultural Experiment Station Research Reports
In Kansas, seven to nine million acres of winter wheat are sown annually with grain yields averaging about 40 bu/a. Variety selection and management strategies are critical decisions to maximize wheat yield. Thus, the main objective of this experiment was to evaluate four wheat varieties and their response to six management strategies at three locations in Kansas. These strategies included a farmer practice, enhanced fertility, economical intensification, increased foliar protection, water-limited yield, and increased plant productivity. Locations were pooled based on tillage practice and environment within Kansas; conventional till in central (Hutchinson and Belleville), and no-till in western (Leoti). In …

Management (M), variety (V), and environment (E) greatly influence wheat yield and quality. With the objective of determining the partial influence of V, E, and M, we conducted a field experiment where we imposed four management intensities to five wheat varieties during six site-years in Kansas and Oklahoma. Management intensities were 1) low-input (N fertility for a yield goal of 60 bu/a); 2) high-input (foliar fungicide, sulfur and chloride fertilizers, growth regulator, and nitrogen (N) fertility for a yield goal of 100 bu/a); 3) high-input minus fungicide; and 4) high-input minus additional N. We selected commonly grown wheat varieties with …
