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.
07-2022 Burdine Developing Agronomy Leaders Annual Report
Agronomy is a diverse field of study in plant and soil sciences which include external factors such as: entomology, genetics, physiology, biology, and chemistry. Recent trends in undergraduate enrollment show many students prefer to specialize in a specific science rather than a generalist discipline like agronomy. As the number of applied-science agronomists decreases, we face a shortage of individuals with the knowledge to perform field diagnostics, develop overall farm management plans or conduct quality research. As the number of trained field agronomist declines, having access to people that can answer day-to-day questions could become a serious issue.
06-2022 Impact of Cover Cropping System on Soybean Grain Yield and Soil Health on Animal Performance
In Mississippi, opportunities exist to combine crop and livestock enterprises in a manner that imparts major benefits to the environment, while simultaneously generating more revenue for agricultural producers. These integrated crop-livestock systems (ICLS) can potentially increase crop yields, enhance natural resource utilization, exploit natural pest control processes, reduce nutrient concentrations and environmental risk, improve soil health parameters, and provide alternative sources of revenue through livestock marketing.
04-2022 Prevost Investigating High Mg Soils and the Impacts on Soybean Production
Magnesium is a critical nutrient for crop development and grain production that is commonly found to be in moderate to high ranges throughout the Mississippi Delta. 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 negative effects extending beyond that of simple potassium antagonism. High magnesium can also negatively impact soil structure and related functions. As clay particles disaggregate (i.e., disperse) under high magnesium conditions soil pore space decreases resulting in crusting and compaction thereby reducing soil aeration and water infiltration/internal drainage.
02-2022 Bryant Fertility and Agronomic Resource Management for Soybean Annual Report
Near record high fertilizer prices has placed increased strain on already small profit margins. For this reason, up to date non-biased research data is necessary to ensure that all soil fertility management decisions are creating not only maximum yield but profitability as well. An example of this would be ensuring the any yield increases associated with micronutrient applications are similarly increasing net returns. Many growers in Mississippi also face K deficiency on a regular basis. As K is mobile in plant tissue and early detection is critical, we must ensure that tissue samples are being collected from the correct location in the plant canopy. Due to relatively flat landscape of the Delta region of Mississippi, flooding is a problem that many soybean growers must deal with on a fairly regular basis. After flooding events growers are looking for ways to accelerate soybean recovery. With this, many growers will make a foliar application of N with the belief that it supplements what has been lost from root inactivity and hastens recovery time. It is also crucial that research personnel continually collect production field level data to stay abreast of ever-changing soil conditions and be able to proactively prepare for possible issues. Specific objectives are 1) Data collection; 2) Establishing optimum tissue sampling location within a plant canopy for early deficiency detection of plant-mobile nutrient potassium; 3) Establishing optimum boron fertilizer application rates and timings for soybean grown on soils ranging from clay to sandy loam; 4) Determine the effect of foliar N applications on soybeans subjected to flooding during the late vegetative to early reproductive growth stages; and 5) Provide first-hand learning opportunities for existing and new soil fertility programs.
