65-2023 Varner MSSOY Website Annual Report
The Mississippi Soybean Promotion Board (MSPD) websites are hosted by the Mississippi State University Extension Center for Technology Outreach (ECTO). ECTO has worked to ensure that the website is available and functioning by monitoring the server, applying patches, testing backups and offsite replication.
24-2023 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.
41-2023 North VIDEO SUPPORT FOR MISSISSIPPI SOYBEAN PRODUCERS Annual Report
By informing the farmer of the results of their checkoff dollars, these videos show that their support isn’t wasted. Furthermore, presentations made by experts help inform the producer of important news, education, and relevant information to help them become more efficient.
62-2023 Feng Increasing soybean field drainage systems to allow farming operations earlier in wet springs and reduce nutrients and soil losses Annual Report
area was 2.22 million acres and had a total value of $1.49 billion. The majority of the annual rainfall in MS occurs in the fallow season from December to April. Flooding or waterlogging has been one of the major concerns that could potentially lead to planting delay, and losses in yield, soil and nutrients through surface runoff and leaching. Installation of agricultural drainage tiles can potentially result in large returns by improving crop productivity and conserving soil and nutrients. In MS, some farmers have started to invest in drain tiles. In East MS, drain tiles installation has now become a practice. In general, tiles are buried 2-3 feet deep, spaced 30-100 feet apart, and sloped at 0.1% or about a 1-2 feet drop over 1000 feet. Most drainpipes are around 4 inches in diameter and can run into 6-8 inches. Drain tiles are designed to drain the excess water from the fields within 24 to 48 hours following rain. The flow velocities range from 0.5 to 1.4 feet per second based on the soil type. In fine sands and silt soils, the flow rate is 1.4 feet per second and in clayey soils, the flow rate is 0.5 per second.
44-2023 Mulvaney Improving agronomic efficiency for Mississippi soybean producers Annual Report
The benefits of using precision planters have been more widely documented in corn systems than in soybean systems. Although soybean is more plastic than corn, the use of precision planting technology in soybean systems is expected to show ROI with faster planting speeds, reduced labor costs, and perhaps reduced seeding rates. 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). Optimal planting speed with mechanical planters is generally around 5-6 mph, but during Year 1 of this project, we were able to demonstrate adequate stands without any yield loss after planting at speeds up to 9.5 mph. If producers can increase planting speed without sacrificing stand or yield, this should result in fewer labor hours and more time to manage early-season fertility and weed control, as well as reduce the risk of getting caught by untimely rainfall during the planting season.
21-2023 Bhandari Assessing Micronutrients Application for Efficient Soybean Production in the Mississippi Annual Report
In recent years, the increase in soybean (Glycine max L.) cultivation due to higher soybean grain sale prices has increased interest in maximizing yield with high-input crop management strategies, including micronutrient application (Orlowski et al., 2016; Gasper et al., 2018). Micronutrients are essential to plants, and their deficiency may limit critical plant functions, resulting in reduced yield and quality (Orlowski et al., 2016). Moreover, high-yielding modern soybean cultivars may require more nutrients, especially in high-yield environments (Thapa et al., 2021). Therefore, it is crucial to use optimum nutrient management to maximize yield by protecting soil health, improving net farm profitability, and minimizing negative environmental impacts.
61-2023 Sabanadzovic Universal detection and identification of soybean-associated viruses Annual Report
Several new and/or emerging viruses have been recently reported in different crops in the USA (stone fruits, grapevines, cotton, etc.) because of introduction (importation) of exotic viruses, or “spill-over” from non-cultivated plants to agricultural fields. These new emerging viruses represent significant threat for agriculture and require specific control measures as they are spread by insect vectors. Unlike fungal pathogens or insects, there is no chemical control against viruses. Accordingly, efficient control strategies in case of viruses rely on prevention and/or an early detection/identification. Delayed awareness about virus infections often results in serious economic damages (yield losses) and high costs associated with their managing. During each of the past several years our lab received several symptomatic soybean samples from MSU extension experts or consultants/farmers which resulted negative when tested with traditional methods for common soybean viruses, therefore suggesting that unexpected (new) viruses may be present in those plants. Therefore, we propose to carry out surveillance activities aimed at: i) an early identification of any viruses (known and unknown) associated with soybean production by combining and applying highly sensitive and unbiased new technologies and approaches; ii) design and development of virus-specific diagnostics for all viruses identified in this work.
