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.
10-2021 Tagert Low-Cost Precision Agriculture Solutions for Advancing Irrigation Efficiency Annual Report
On fields where the distribution of wetter/drier areas match well with the geometry of pie-shaped sectors, the use of sector control variable-rate irrigation is an ideal solution for advancing irrigation efficiency beyond what is possible with conventional uniform irrigation.
09-2021Residual Control of Commonly used Insecticides in Soybean, Final Report
Due to increased costs of insecticides, particularly newer products, the most asked question by growers is length of control. This drives many decisions on product choice.
07-2021 Developing Agronomy Leaders with Day Camp, Bowl Contest and Science Projects Annual Report
Recruiting highly motivated youth into careers dedicated to production agriculture, and specifically soybean research should provide Mississippi producers with a competent group of individuals who will move agriculture forward. This project has the potential to attract the next generation of producers, scientists, Extension agents and industry personnel to keep soybean production in Mississippi healthy and vibrant.
06-2021 Rushing Impacts of cover cropping system on soybean grain yield, soil health, forage production, and animal performance annual report
This project seeks to evaluate the impact of cover cropping and livestock grazing on two distinct soil types to determine the ability for ICLS to be profitable in Mississippi soybean production systems.
04-2021 Investigating high magnesium soils and the impacts on soybean production
High soil magnesium exacerbates the already low percentage of available potassium by super-saturating exchange sites with its double positive charge and essentially crowding out the potassium ions. This magnesium induced antagonism is known and generally addressed by increasing potassium rates in fertility recommendations. New knowledge suggests that high magnesium levels could be a more widespread issue than previously considered, with negative effects extending beyond that of simple potassium antagonism. High magnesium can also negatively impact soil structure and related functions.
01-2021 Cook Insect Management In Soybeans Annual Report
“Routine” studies to evaluate current insecticides, along with reports from growers and consultants provide the first indications of pending insecticide resistance issues. Current market conditions have reduced profit margins considerably. The most informed and economical insect management decision is always important, but may be even more important when profit margins are small. To keep information current, studies must be regularly conducted to evaluate management strategies and tools and to provide information on unexpected insect issues.
