22-2021 Cox Development of Fertilization Practices for Sustaining Mississippi Soybean Yield and Quality Final Report
Information regarding soybean yield response to in-season fertilizer-K application time is limited to growth stages prior to the onset of R1. Research is limited on new higher yielding soybean varieties that are on the market today. The objective of this study was to evaluate influences of in-season potassium application timing during reproductive growth stages on soybean yield on clay and silt-loam soils.
21-2021 Shankle Effect of Cover Cropping Systems on Dryland Soybean Plant-vigor, Growth, and Yield Annual Report
Therefore, the goals of this project were to evaluate various cover crops in conjunction with different planting dates and nutrient sources to determine the optimal combination for integrating cover crops into a cropping system.
20-2021 Bond Weed Management Programs for Mississippi Soybean Production Final Report
Mixing herbicides with different modes of action provides the potential for increased weed control and a reduction in application costs. However, some components of herbicide mixtures can synergize or antagonize others. Interactions between components of herbicide mixtures have been documented. It is important to identify effective programs for broad-spectrum weed control in these technologies. Recommendations for weed control in Mississippi soybean will originate from this research.
18-2021 Biochar seed coating as an approach for preventing root infection of soybean seedlings by Macrophomina phaseolina and other soil fungi final report
The proposed research is to determine if biochar, which is a type of charcoal produced as a soil amendment, can be used to protect germinating soybean seeds from root infection by fungi that use (-)-botryodiplodin or other charcoal-binding mycotoxins to facilitate root infection by killing meristematic tissue.
16-2021 Evaluation of overseeding of cover crops in dryland soybeans at different timings annual report
Cover crops can be used as a best management practice for reducing nutrient losses through erosion, runoff, and leaching, increasing organic matter in the soil by cover crop residues and ultimately, enhancing nutrient cycling and soil fertility
IRAC MOA List
The Insecticide Resistance Action Committee (IRAC) publishes a mode of action (MOA) classification scheme that can be used to select insecticides that will provide an effective insecticide resistance management strategy.
14-2021 Determination of organisms affecting soybean seed quality and fungicide efficacy in reducing associated losses annual report
As a means of reducing Phomopsis seed decay in subsequent seasons the current management strategies include crop rotation with non-hosts, tillage, fungicide applications during pod-fill, and resistant cultivars. However, information regarding efficacy of fungicide applications and cultivar resistance within the current commercial offerings is limited. The objectives of this research will improve soybean resistance to reduced grain quality by screening germplasm and developing new and improved breeding lines, and develop best management practices to address the soybean production issues associated with reduced grain quality.
13-2021Row Crop Irrigation Science Extension and Research (RISER) Program Annual Report
Declining aquifer levels, coupled with impending well monitoring, serve as a catalyst to improve water use efficiency. The RISER program has identified several technologies and management practices that have the potential to eliminate the 300,000 ac-ft/yr overdraft on the Mississippi Alluvial Aquifer while ensuring that producers stay within permitted irrigation limits.
12-2021Managing Iron Deficiency Chlorosis (IDC) Through a Cropping System Approach Annual Report
This project puts all cropping systems including variety selection, cover crops, seeding rate and cropping systems together in one field with the goal to find relief from IDC and reduce yield loss.
