40-2022 Evaluating Nutrient Availability Following Cover Crops in Mississippi Soybean Production Systems Final Report
Numerous studies evaluating cover crops and their influence on soil nutrient availability have been carried out across the U.S. While these studies tout greater nutrient availability following a cover crop, the actual agronomic value to the subsequent cash crop in a nutrient deficient situation is largely unknown. Similarly, knowledge of the effects of cover crops on P2O5 and K2O availability in Mississippi soybean production systems is lacking. Insufficient P or K availability in soils result in lower soybean yields. 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.
39-2022 Management of Redbanded Stink Bug in MS Soybean Production Systems Final Report
Redbanded stink bugs were the most abundant stink bug species present in 2017 in Mississippi. This species is extremely damaging and often enters the fields much later than our traditional species (Green, Southern Green, and Brown). The redbanded stink bug is capable of causing severe economic damage well after stink bug sprays are recommended to be terminated for our native species (R 6.5). There were reports of several fields that were complete losses and many others with substantial deductions at the elevator from damage due to this pest. Redbanded stink bugs are extremely damaging and harder to control with commonly used insecticides. This project will outline objectives to better understand management tactics to manage RBSB in Mississippi to ensure profitability for growers.
32-2022 Ahn Development of molecular diagnostic method for the diamide resistance in soybean looper Annual Report
The project is a continuation to complete the following objectives. (1) Establish and maintain a resistant strain of soybean looper from Puerto Rico, (2) Compare target site genes of susceptible and resistant populations, (3) Conduct standard diamide bioassays for soybean looper populations collected in Mississippi, (4) Identify detoxification genes that differentially expressed between the two strains, and (5) Monitor resistance in field populations with a molecular diagnosis kit.
29-2022 Gore Delta Agriculture Weather Annual Report
Weather data is used for current research projects and also this sites keeps historical weather data for all locations. You can see individual fields and study growth and development of your crop.
28-2022 Cook Insect Management Strategies Using Insect Growth Regulators in Mississippi Soybeans Annual Report
To examine the impact of selected insect growth regulators applied at the R3 to R4 growth stages on insect pest infestations and soybean yield.
24-2022 Chesser MSU Seed and Agricultural Technology Short Course Sponsorship Annual Report
The MSU Seed and Agricultural Technology short course is an annual event (since 2015) held at MSU to impact and strengthen the Seed & Ag. Technology industry/value-chain. The short course promotes industry advancements, provides current trainings and resources, and provides a networking opportunity for industry professionals, stakeholders, and MSU personnel.
20-2022 Bond Weed Management Programs for Mississippi Soybean Production Annual Report
Glyphosate-resistant Palmer amaranth and Italian ryegrass are the largest weed threats for Mississippi crops. Palmer amaranth competes for nutrients, water, light, and space because of its rapid, upright growth habit and allelopathic properties. Italian ryegrass can jeopardize burndown herbicide programs. Fields with GR Italian ryegrass not controlled at burndown will contain significant residue at planting. Residue will impede planting practices, contribute to competition between soybean seedlings and GR Italian ryegrass, and hinder herbicide programs due to inadequate coverage.
13-2022 Gholson 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. However, the adoption of Best Management Practices (BMPs) by producers in the Mississippi Delta is minimal. The RISER (Row Crop Irrigation Science Extension and Research) Program can serve as the primary means to facilitate widespread adoption of the latest irrigation management research findings across the Mississippi Delta. The goal of the project is to evaluate, demonstrate, and transfer innovative and proven technologies that can result in water conservation by conducting coordinated extension activities throughout the Mississippi Delta.
11-2022 Mulvaney Increasing planting speed using off-the-shelf precision planting technology Final Report
Mechanical planters are the most commonly used equipment for planting soybean in Mississippi. However, optimal planting speed with mechanical planters is generally around 5-6 mph, though faster ground speeds are often used. During the planting season, producers face pressure to get as much land planted as quickly as possible during tight calendar and weather windows. New metering and seed delivery technology claims to enable planting at faster speeds without sacrificing singulation or stand establishment (Kinze Manufacturing, 2020). Still, these tools require testing and validation under Mississippi conditions.
