46-2021Evaluating cover crops to determine the best management practice for the suppression of tall waterhemp and Italian ryegrass final report
To combat herbicide resistance among weeds, non-herbicide methods of control, such as cover crops, are becoming widely adapted. Experiments were conducted to determine how to effectively establish and manage cover crops in order to suppress tall waterhemp and Italian ryegrass and to assess their overall impact on soybean growth and yield. Various cover crop establishment methods were evaluated, and it was determined that interseeding at the R7 growth stage of soybean was the least effective method for proper cover crop establishment.
40-2021Evaluating Nutrient Availability Following Cover Crops in Mississippi Soybean Production Systems annual report
. Insufficient P or K availability in soils result in lower soybean yields than the achievable maximum. A previous large scale study conducted throughout Mississippi determined that soybean yields could be increased by an average of 8 to 10 bushels with the addition of P2O5 or K2O fertilizers when soil nutrient values were determined to be insufficient by the state soil testing lab. With this information available, no research has been conducted in Mississippi to determine how cover crops may affect the subsequent soybean crop when P or K may be limiting, and how these cover crop systems may interact with a fall P or K fertilizer regime.
39-2021 Development of a predictive model to determine the influence of weather on the northern range expansion of redbanded stink bug annual report
Understanding how weather impacts RBSB abundance and distribution was achieved through (i) the continuation of monitoring to delimit the annual range of this pest and (ii) targeted investigations of the environmental conditions that lead to annual changes in pest abundance across the landscape. Ultimately, we hope to use this information to forecast annual potential impacts from redbanded stink bug.
33-2021 Developing Improved Soybean Lines for Seed Composition, Quality, and Heat Tolerance in Mississippi Final Report
To our knowledge, there are no commercial soybean cultivars that are heat-tolerant with high levels of seed composition (seed protein, oil, and minerals) and quality components (reduced seed damage including reduced green seed, seed wrinkling, hard seed, and diseased seed). Therefore, developing heat tolerant germplasm with high seed composition and quality is essential.
32-2021Development of Molecular Diagnostic Method for the Diamide Resistance in Soybean Looper Annual Report
the goal of this project is to develop a rapid and accurate diagnostic method based on DNA sequences to screen populations of soybean looper for resistance to diamide insecticides. To achieve this goal, we postulate four objectives for year 1 with a fifth overall project objective that will be initiated in years 2 and 3.
29-2021Delta Agricultural Weather Annual Report
The Center has continued to build its network throughout the state of Mississippi. The Center added 5 full new weather stations to its network. This has increased our network to 31 stationary stations. All data can be viewed every in real time, hourly and daily readings are archived for past viewing.
28-2021 Evaluating New Production Inputs that will contribute to High Yield Soybeans Final Report
Through observation and discussion with growers, there are a myriad of factors that limit yield. Oftentimes, these factors are things that cannot be adjusted mid-season such as drainage. With that being said, growers in some high yield environments want to increase profitability through different mid-season management strategies.
27-2021 Development of an Automated System to Incorporate Holes in Lay-Flat Irrigation Tubing During Initial Deployment in Mississippi Soybean Production Systems Annual Report
The ability to irrigate row crops from the Mississippi River Valley Alluvial Aquifer (MRVAA) is crucial to the sustainability of soybean production in Mississippi and the Mid-South. However, groundwater is a limited resource; therefore, even in humid regions, groundwater must be prudently managed to ensure its continued viability and protect the ability to groundwater access for agricultural production.
25-2021Using Drones to Sample Insects in Soybeans Final Report
The use of drones in insect sampling has been studied in a few situations but is still in its infancy. Most drone sampling research to date has used imagery as the means of sampling, often measuring plant stress rather than counting insects directly. However, to make this monitoring method useful in regions like Mississippi with multiple potential pests causing similar injury, an insect recognition method is needed.
