Cotton Insect Management
Presented by: Dr. Gus Lorenz, Professor-Extension Entomologist, University of Arkansas Division of Ag – Extension
Each year, the bollworm (Helicoverpa zea, Bodie), infests 100% of cotton planted in Arkansas. It remains a major pest of post-bloom cotton in the Mid-South despite widespread use of transgenic varieties. Dual gene Bt cotton does not always provide adequate protection from lepidopteran pests to maintain potential yield. In years when bollworm populations are high, foliar insecticides are commonly used to supplement control of cotton bollworm. In recent years we have seen a decline in control of bollworm with dual gene cotton. A recent analysis of data indicates that there has been an increase in damage to squares which might indicate tolerance is developing to dual gene technologies. Economic loss to the grower based on cost of treatment and reduction in yield due to this pest totals more than $1.7 million or $9.41 per acre, in 2020 that figure is much higher. We will discuss the impact and efficacy of foliar over sprays on conventional and dual-gene cottons, and the role of 3 gene cotton for growers in the Midsouth.
Management of Cotton Insects to Maximize Profit
Presented by: Dr. Whitney Crow Assistant Professor, Extension Entomologist, Mississippi State University

Cover Crops Reduce Early Season Weed Competition
Presented by: Dr. Tom Barber
Extension Weed Specialist, U of A Division of Agriculture
Cover crop acreage is increasing in Arkansas for several reasons including potential benefits in weed control. Palmer amaranth (pigweed) emergence has been significantly reduced when a cereal rye cover crop was implemented. However, successfully reducing pigweed emergence can be directly related to cover crop termination timing. The research data presented provides appropriate cover crop termination timings to significantly reduce Palmer amaranth emergence at planting and beyond.
Weed Control In Cover Crops: What Worked, What Didn’t; Cover Crop Termination Timing
Presented by: Wes Kirkpatrick
Arkansas Farmer: Cotton
Kirkpatrick will discuss weed control efforts he’s tried in cotton that was planted into a cereal rye cover crop. Some have worked and some have not, especially in relation to pigweed. He will examine how the timing of the termination of a cover crop affects weed growth during the growing season.
After receiving his Bachelor’s Degree in biology with a minor in fisheries and wildlife management from the University of Arkansas at Little Rock, and his Master’s Degree in agronomy with a focus on soil science from the University of Arkansas at Fayetteville, he became a county agent with the University of Arkansas Division of Agriculture in the early 2000s in Desha County, Arkansas. Desha County has over a quarter million acres in agricultural production, which primarily includes cotton, soybeans, corn, and rice. There he met many farmers and his future wife, Vonda, a fifth-generation Desha County row crop farmer. He’s been associated with that farm since his marriage in 2003 and became a full-time farmer in 2016, now just completing his sixth full time crop.
Cotton Yields –How High Can We Go?
Presented by: Dr. Fred Bourland
Professor, University of Arkansas
Average cotton yields in Arkansas have increased from a record low in 1930 (119 lb/a) to a record high in 2019 (1185 lb/a). Four progressively increasing yield plateaus have been experienced during this time span with each plateau having different causes and remedies. Can yields continue to increase above the latest and highest plateau? Yield potential of a cotton plant far exceeds our current yields, but we may now be approaching yield limits imposed by our environment.
Cotton Production Costs –Where Can We Save?
Presented by: Ray Benson
County Cooperative Extension Agent, Staff Chair, Mississippi County, AR, University of Arkansas
With a possible high yield plateau and stagnant cotton prices, increased profits can only be achieved by reducing production costs per unit of production. Profits might be improved by matching inputs to historical yield potential within fields (site-specific management). Prescription seeding rates, variety selection (within a field), fertilization, irrigation, and pest control could improve efficiency of inputs and enhance profits.
Identifying and managing disease of cotton in the Mid-southern United States
Presented by: Dr. Tom Allen
Associate Extension Research Professor, Plant Pathologist, Delta Research & Extension Center
Numerous diseases of cotton continue to remain important in the Mid-southern cotton production system. Seedling diseases, foliar diseases, as well as diseases caused by nematodes can all result in yield-losses depending on the year and given situation.
Insects, Weeds, And Diseases. What We Saw In 2020
Presented by: Tucker Miller, III
Mississippi Consultant, Miller Entomological Services, Inc.
Miller will discuss the BG 3 varieties he tested the past year, including three Delta Pine varieties: 2012, 2020 and 2038; two Phytogen: 400 and 390; Nexgen 4936 and Stoneville 4990. He will give a description of how they performed. He also will provide some options to use in place of Dicamba in case farmers lose that treatment. That includes planting Phytogen’s Enlist cotton and using 2-4,d or go back to the old way of planting cotton by using cultivation and Liberty. He also plans to discuss some diseases he’s had to combat this year including bacterial blight and a little target spot.
Though he’s been consulting for the past 48 years, he first began checking cotton at age 15, making it 50 years he’s been in the field. Today, he consults on 25,000 acres of cotton, 5,000 acres each of soybeans and corn, as well as 1,000 acres each of peanuts and vegetables. He grew up on a farm where cotton, soybeans and rice were raised; on his own 2,000 acres, he raises soybeans, wheat and corn, but also raises cotton some years.
Potential of UAS-Based Multispectral Imagery for In-Season Nitrogen Management in Cotton
Presented by: Dr. Simerjeet Virk
Assistant Professor & Precision Ag Specialist, University of Georgia
Latest availability and integration of high-resolution multispectral sensors on unmanned aerial systems have expanded the capabilities for time-sensitive and rapid data collection over large fields in the season. Cotton nitrogen management in the season can have a significant impact on the crop growth and subsequent lint yield. This study investigated the potential of multispectral imagery-collected using an unmanned aerial system-for estimating nitrogen status in cotton during the growing season, with a goal of developing correlations that can be used to detect and address in-season Nitrogen variability in cotton.

Presented by: Matt Fryer
Instructor – Soil Science, University of Arkansas Systems Division of Agriculture Cooperative Extension Service
Presented by: Craig Shelton
Certified Crop Advisor, Natural State Crop Consulting
Matt Fryer -The term soil health is vast and includes production practices like no-till and cover crops. On-farm demonstrations were implemented at 20 sites comparing cover crops and no-till to conventional production practices. Components of comparison include: bulk density, aggregate stability, soil nematode populations, in-season moisture sensor data, water infiltration rates, yield, and economics.
Craig Shelton -Many years of crop consulting experience has led Natural State Crop Consulting to advise toward no-till production practices and the use of cover crops. There are challenges and benefits, but the benefits are apparent by the reduction of inputs and overall profitability on a large scale.
Update on aphid vectors, virus spread and management of Cotton leafroll dwarf virus (CLRDV) in the U.S.
Presented by: Dr. Alana Jacobson
Associate Professor of Entomology, Auburn University
Cotton leafroll dwarf disease (CLRDD), caused by Cotton leafroll dwarf virus (CLRDV), is an emerging aphid-transmitted virus in the U.S. Symptoms of this new disease include crinkling, cupping, thickening of leaves, reddening of leaf veins and petioles, dwarfing of the plant, reduced boll set, swollen and brittle stems, accentuated verticality and decreased yields. Results of research conducted in 2019-2020 will be presented to highlight what has been learned about virus spread by aphids, and the effectiveness of management strategies on reducing virus incidence and yield loss associated with this virus.
Management of Cotton Aphid and Implications for CLRDV
Presented by: Phillip Roberts
Professor and Extension Entomologist – Cotton, University of Georgia
Cotton aphid infest a high percentage of cotton acreage in the Southeast and is a potential pest of cotton in the region. The recent detection of Cotton leafroll dwarf virus (CLRDV) which transmitted by cotton aphid necessitates further investigation into the biology and ecology of cotton aphid in cotton production systems. Additionally, field trials investigated the influence of cotton aphid management on CLRDV incidence.

Vice President & Chief Sustainability Officer, Cotton Incorporated
Presented by: Karen Wynne
US Program Coordinator, Better Cotton Initiative
A production field of cotton located at the Agricenter in Memphis, TN was used as a model for participation in both the US Cotton Trust Protocol and BCI Better Cotton Programs. Prior to the start of this study, cotton was produced using conventional tillage without the use of cover crops. In 2020, the field was split comparing practices to improve soil health including cover crops and greatly reduced tillage compared to the standard practices of conventional tillage using no cover crops. Improvements in sustainability metrics between the two systems will be discussed and compared to the US Cotton Industry goals for improvement. Representatives from both BCI and US Cotton Trust Protocol Programs will discuss their respective programs to meet the improved sustainability needs of our supply chain.

Presented by: Dr. Kip Balkcom
Research Agronomist, USDA-ARS National Soil Dynamics Laboratory
Presented by: Adam Chappell
Arkansas Farmer: Cotton
Adoption of cover crops has created more sustainable cotton production systems for many farmers in the Southeast. Some benefits of cover crops include improved soil moisture storage, reduction in herbicide inputs, and enhanced soil health. However, managing cover crops is not without challenges. In this session, speakers will address how management challenges were overcome to successfully incorporate cover crops into cotton production systems.
Benefits and challenges of cover crops in West Tennessee cotton
Presented by: Dr. Tyson B. Raper
Cotton Specialist, University of Tennessee
The integration of cover crops into Tennessee cotton production poses numerous benefits including increases in infiltration and water holding capacity, increases in the effective rooting zone, increases in weed and insect control, and reductions in erosion. Unfortunately, cover crops also pose unique challenges in cotton production, particularly within the Tennessee no-till system. During this presentation, Mr. Matt Griggs, a 5thgeneration row crop producer in Humboldt, TN, will highlight a few of the benefits he has captured on his farm and some of the practices he has adopted to maximize the likelihood of successful cover crop integration.
A systems Approach To Integrate High Biomass Cover Crops Into A Cotton Production System
Presented by: Matt Griggs
Tennessee Farmer: Cotton, Corn, Soybeans, Wheat, Cover Crops
Griggs will discuss a systems approach to integrate high biomass cover crops into his cotton production system. He will include strategies to successfully plant cotton into living cover, and will share data from his farm showing increased water infiltration, greater water holding capacity, increased nutrient concentration, and better weed control when integrating cover crops. He has been large scale cover cropping since 2014 and planting green since 2015.
This year Griggs is working approximately 2000acres. 500 acres corn, 630 acres cotton, 350acres full season soybeans, 500 acres wheat, and 500 acres of double crop soybeans.
He has been on the farm all his life but started working full time with his father, Bobby Griggs, upon graduation from college in 2002. He took over the farm full time in June 2005 when his father suddenly passed away after a short bout with illness. Matt was married to Kelly Griggs in 2006 and she came to work full time on the farm in 2010. They have three children: Paige is 23 years old, Nate,18, and Carter,12.
Griggs is a fifth generation farmer on the family farm which has been in the present location since 1882. At first, the Griggs family primary business was a cotton gin with some farming on the side. The farming operation grew when his father, Bobby, took over in the 1970’s when he graduated college while Matt’s grandfather, Wayne Griggs focused primarily on the gin. The gin was shut down after the 1995 crop. When Matt took over the farm, it consisted of900 acres. Matt more than doubled the size of the operation and turned their equipment into a fleet of modern, high tech equipment.
Matt attended the University of Tennessee at Martin in Martin, TN and received his bachelor’s degree in Plant and Soil Science in 2002.
There’s much historical information about the Griggs farm on its website, www.griggsfarmsllc.com.
The Griggs farm was featured last year on the 8-part docuseries, “The American Farm,” on The History Channel.

Presented by: Dr. Jarrod T. Hardke
Rice Extension Agronomist, University of Arkansas
Producers are increasingly looking for cultural management options in rice that will optimize their production. One of the most notable areas of interest is in planting arrangement and seeding rate. The overall goal is to optimize grain yield and milling yield while reducing seed costs and equipment costs. Trials evaluating row spacing and seeding rate combinations for varieties and hybrids are ongoing. Results of these studies and their impacts on production will be discussed.
Managing Nitrogen in Furrow-Irrigated Rice Production
Presented by: Justin Chlapecka
Phd Graduate Research Assistant, University of Arkansas
Furrow-irrigated rice acreage continues to increase across the Mid-South and is estimated at over 200,000 acres in Arkansas alone. Nitrogen (N) fertilization has the potential to be much less efficient where a flood is not present. Studies were conducted in 2018, 2019, and 2020 in commercial fields on both clay and silt loam soils across Eastern Arkansas to determine the optimal N management regime for furrow-irrigated rice. Findings from the three-year study across 16 sites will be discussed –including grain yield, milling yield, and recommendations depending upon soil type.
US Rice Sustainability Programs and Rice Leadership Development Programs
Presented by: Dr. Steve Linscombe, Executive Director, USA Rice Federation
The US Rice Industry has a rich history of sustainability throughout the field production and processing sectors. From 1980-2015 the industry reduced environmental impacts by increasing land use efficiency by 39%, decreasing water use by 52%, decreasing energy use by 34%, decreasing greenhouse gas emissions by 41% and decreasing soil loss by 28%. The industry has established additional goals to continue to make improvements in each of these metrics over the next 15 years. The progress and goals will be discussed as well as all programs such as webinars, podcasts, and social media that is being used to convey the rice sustainability story. The Rice Leadership Development Program will also be discussed.
Sustainable Practices For Raising Zero-Grade Continuous Rice
Presented by: Jim Whitaker, Arkansas Farmer: Rice, Corn, Soybeans, Cotton
Whitaker will discuss whether row rice can add benefits to rice farming and keep it more sustainable. He will discuss the pros and highlights the cons of row rice. He also will explain “Why we do what we do” and how little efforts add up to not only help the environment but also put dollars in your bottom line. He described some of the “little things” as no-till or minimum till, nutrient management and alternate wetting and drying (AWD). He has seven years of experience with AWD and together with his brother, Sam, they raise rice, soybeans, cotton, and corn. He has been farming for 27 years.
Insect Management and Insecticide Termination in Rice
Presented by: Nick Bateman, Extension Entomologist, University of Arkansas
Presented by: Chase Floyd, Graduate Student, University of Arkansas
Multiple studies were conducted to determine the efficacy of insecticides for rice water weevil in flooded rice, as well as rice billbug in in furrow irrigated rice. These tests show that combinations of insecticide seed treatments were the most consistent control options for both of these pests. Assays were also conducted on rice stink bugs to determine tolerance levels to Lambda cyhalothrin along with multiple in-field efficacy trials.
What will the US rice market look like in early 2021?
Presented by: Milo Hamilton, President and Senior Economist, Firstgrain Inc.
Right now that seems like a decade into the future. Here is why. By then, China will have suffered the worst growing season since 1961 and yet they expect a bumper rice harvest. Go figure! India will have a bigger crop but its neighbors, not so much. Most likely drought will trim acres in South America despite huge rice prices currently. The US faces a much larger crop, huge domestic demand, and a delayed start to its exports because the stocks were so tight. Over the next 6 months the US Dollar should weaken, and we will know who will be in the White House after a bitterly fought campaign.
One thing is likely: we will have left a crucial something out of our list Why so? It is because last year at this time we did not forecast near record rice prices in June, a near record price drop in July, a global pandemic, the near-record storm in Louisiana and urban race riots, massive unemployment, the unprecedented collapse and rebound in US equities. Oh yes, we forgot to mention that two of the three largest fires in California history are raging across the state right now. Fire, wind, rain, disease, financial ruin. What horsemen of the Apocalypse did we fail to mention?

Everything Old is New Again: Managing Sedges in Rice
Presented by: Dr. Thomas (Tommy) Butts, Extension Weed Scientist, University of Arkansas, System Division of Agriculture
Multiple sedge weed species, including yellow nutsedge, rice flatsedge, and most recently, white margin sedge, have become increasingly troublesome in Arkansas rice acres. The correct identification of the sedge species in the field is a necessity to correctly select an effective herbicide. Additionally, getting the most out of our herbicides requires optimizing the application process. This talk will discuss the identification of common problematic sedge weeds, explore white margin sedge and best management efforts for this species, and identify aerial application methods that can improve efficiency and control.
The Balancing Act of Managing Grasses and Sedges in Rice
Presented by: Austin Miller, Crop Consultant: Nutrien Ag Solutions
The theme of weed control in rice in recent years has become a mandatory two-way approach. It comes down to a decision of which is your more problematic weed at the time, a series of grass species or sedges. After attacking whichever weed is the greater of the two evils, it is important to be ready for a quick post flood application to clean up the other. This talk will discuss the importance of both pre and post flood scouting of these weeds. Additionally, it will consider different control options for white margin sedge, a relatively new problem weed which has become increasingly widespread and troublesome in my area, and how these control options can play into the herbicide program that is already in place.
Keys Fertilization of Hybrid and Pureline Rice Cultivars with Potassium
Presented by: Dr. Trenton L. Roberts
Extension Soil Fertility Specialist, University of Arkansas
Rice is an important component of many crop rotations across the Mid-south and for many states such as Arkansas, hybrid rice cultivars account for roughly half of the acres produced to rice. Recent work at the University of Arkansas has identified a stark difference in the response of hybrid rice to potassium (K) fertilization compared to pureline cultivars. On soils with very low and low soil test K, where we see highly significant increases in pureline rice yields with K fertilization, we see no yield increases for hybrid rice on these same soils. These findings suggest that hybrid rice does a better job of exploring the soil and scavenging nutrients, but also may be mining soil nutrients at a faster rate. Further research is needed to identify the rate at which hybrid rice removes K from a production system and whether or not K fertilization rates need to be adjusted to account for the differences in nutrient demand across rice cultivars.

Nitrogen Management Challenges in Furrow-Irrigated Rice and Available Nitrogen Technology Solutions
Presented by: Cullin Minter Strategic Account Manager, Koch Agronomic Services, LLC
With reduced tillage furrow-irrigated rice acres growing and gaining popularity, new challenges exist in nitrogen management for rice producers. In addition to volatilization loss, furrow-irrigated rice creates an environment where denitrification loss can be expected. While urease inhibitors protect against volatilization effectively, once the urea is incorporated by irrigation, below-ground loss needs to be considered. Koch Agronomic Services, LLC has been testing SUPERU® fertilizer in furrow-irrigated rice since 2017. SUPERU is a 46-0-0 fertilizer with both a urease inhibitor and nitrification inhibitor infused homogenously in each granule. The two active ingredients provide protection against all three major nitrogen loss mechanisms: volatilization, denitrification, and leaching. We have seen significant yield increases and more consistent results in furrow-irrigated rice fields when using SUPERU.
Evaluation of Nitrogen Management in Furrow Irrigated Rice
Presented by: Dr. Dustin Harrell Professor, Louisiana State University Agriculture Center – Rice Research Station
Furrow irrigated rice (FIR) has increased in popularity over the past three-years and is set to increase in acreage again in 2020. Nitrogen (N) management in FIR is less efficient as compared to traditional flooding due to the alternating wetting and drying of the soil. Several trials were established in 2018 and 2019 to evaluate N management in FIR. Trials evaluated N rates, N application timings, and enhanced efficiency fertilizers.

Soybean Foliar Fertilizer Evaluation: What is Working
Presented by: Dr. Jeremy Ross
Extension Agronomist – Soybean Professor, University of Arkansas, Division of Agriculture Cooperative Extension Service
Many soybean producers apply foliar nutrient products during soybean reproductive growth as a routine production practice. These applications are made in addition to the use of commercial fertilizer products applied to the soil. Due to the narrowing of production margins, many have questioned if these foliar nutrient products increase soybean grain yield and are profitable. In 2019 and 2020, Arkansas collaborated with 12 other soybean producing state to compare the soybean grain yield response to six commercially available foliar nutrient products. Results from the two locations in Arkansas showed no significant yield increase with any of the products evaluated compared to the untreated check. From these initial results, using these products as a routine production practice would not be recommended.
Soil Fertility In Soybeans And When, And When Not, To Use Foliar Fertilizer
Presented by: Robb Dedman
Arkansas Consultant: Ultimate Ag Consulting
Dedman has studied the importance of fertility in soybeans as good fertility relates to yield. “There are four things that contribute or fail to contribute to good yields,” he says. “In soybeans, we don’t typically get a good response from foliar type fertilizer.” However, there are times when the opposite is true. He will discuss when to use foliar fertilizer.
His first experience with consulting was when he starting scouting rice while in high school under Dr. Nathan Slaton who was the Extension agent at the time. Dedman holds a bachelor’s degree in agronomy from the University of Arkansas, and presently owns his own ag consulting firm, Ultimate Ag Consulting.
Management of soybean insects for maximum economic returns

Harvest Management Strategies to Optimize Soybean Yield Potential
Presented by: Dr. Trent Irby
Extension Soybean Specialist, Mississippi State University
Environmental conditions during the latter part of the soybean growing season can present a multitude of challenges. Excessive rain may prevent timely application for disease and insect management, or result in delayed harvest due to poor field conditions. Soybean harvest aids have become common practice across much of the Mid-South and can be used to facilitate a faster, more efficient harvest. Given the environmental conditions that are common during the harvest season, it is important to understand harvest aid performance as well as the impact that delayed harvest may have on soybean yield and grain quality.

Alternative Farming Practices Due To Necessity
Presented by: Brett Stewart
Arkansas Farmer: Soybeans
Necessity has led Brett Stewart to toy with some alternative farming practices. No-till has been a good fit going into soybeans. He has been able to establish good stands and maintain yield going straight no-till into both corn stubble and rice stubble with an ordinary Great Plains drill. Most of his patty rice has been converted to furrow-irrigated rice to take away the challenges that levees present post harvest. Also he has had no trouble drilling furrow-irrigated rice straight into both soybean stubble and corn stubble. No-tilling corn has been more challenging, as stands have been a little too uneven and yields are not where they should be, but there is still a cost savings in both tillage and herbicide applications. “I don’t want to give up on no-tilling corn yet though because I have observed better yields for all crops as we get into the third year of no-till in a particular field,” he says. “Right now I am crediting that to compaction issues in the first and second years following conventional tillage. I am excited to continue these cost-saving and time-saving experiments.”
Stewart farms approximately 2,000 acres total of rice, corn, soybean. Currently, each crop consists of about1/3 of his total acres. Some years he plants about 200 acres of wheat, which is then double cropped to soybeans. A first generation farmer, he started his own operation in 2016 and moved into full-time farming in 2017. This is his fourth crop as a full-time farmer. He did not grow up on a farm, but he admired farmers and their lifestyle. His first experience in agriculture was working in entomology for Dr. Gus Lorenz as a seasonal technician during the summers of 2009, 2010 and 2011.
Reevaluation of Fertilizer Recommendations for Soybean Production in Louisiana
Presented by: Dr. Rasel Parvej, PhD
Assistant Professor & Soil Fertility Specialist, Louisiana State University AgCenter, Scott Research & Extension Center, Macon Ridge Research Station
Most land-grant universities have developed fertilizer-P and K recommendations based on topsoil (0- to 4-, 0- to 6-, or 0- to 8-inch depth) P and K availabilities. Although topsoil-based fertilizer recommendations are fairly accurate for soybean production across a range of soil types, it sometimes gives false positive error i.e., soil-test results indicate a positive yield response to fertilization but in fact it does not occur. This may be due to a small amount of subsoil-P and K availabilities at 6-12-inch or deeper depth that soybean roots can easily access and fulfill both P and K need and resulting in no yield response to added fertilizer. Therefore, both topsoil and subsoil nutrient availabilities need to be considered to develop better fertilizer recommendations for soybean production in Louisiana. We reevaluated soybean yield response to five different fertilizer-P (0, 30, 60, 90, and 120 lb P2O5 acre-1) and K (0, 40, 80, 120, and 160 lb K2O acre-1) rates and two different soil-P and K concentrations from 0- to 6- and 0- to 12-inch depths across 14 sites in Louisiana. The results will be presented in meeting. This study will be continued in 2021 and 2022.
Redbanded Stink Bugs: A Louisiana Perspective and Management Tactics
Presented by: Dr. Sebe Brown
Research & Extension Field Crops Entomologist, LSU AgCenter
Redbanded stink bugs (RBSB) are the most economically important insect pest in Louisiana soybeans. RBSB can outcompete and cause more seed yield and quality losses than native stink bugs. Management tactics utilized by Louisiana agricultural professionals, against RBSB, have constantly evolved since the stink bug’s introduction to Louisiana in 1999. This presentation will address the RBSB’s biology, mechanisms for injury, control tactics and management considerations in Louisiana.

ADDRESSING CORN PRODUCTION MANAGEMENT WITH INPUT OPTIMAZATION
Presented by: Dr. M. Wayne Ebelhar (Retired)
Soil Fertility/Crop Production, Mississippi State University Delta Research & Extension Center
The various inputs to corn production have been examined over the last few decades and grain yields have increased from around 50 bu/acre to 180+ bu/acre. The gains in grain yield have been attributed to better genetics (hybrids), increased fertility, better disease and insect control, higher plant populations and sound management decisions. Producers often believe more is better but that is not always the case and the maximum economic yield (MEY) may be different from maximum yield alone. AS inputs increase, net returns tend to decrease per unit. This law of diminishing returns states that in all productive processes, adding more of one factor of production, while holding all others constant (“ceteris paribus“), will at some point yield lower incremental per-unit returns. The law of diminishing returns does not imply that adding more of a factor will decrease the total production, a condition known as negative returns, though in fact this is common.
The research being discussed examines both the addition and deletion of inputs that producers often trigger without scouting or determining the economic implications. This research project was sponsored in part by the Mississippi Corn Promotion Board and the producers of Mississippi. Factors considered included plant population, row configuration, nitrogen rate, phosphorus and potassium application, sulfur, zinc, and fungicide application. Decisions were made without reference to soil testing or scouting. The research techniques included a split plot design with combinations of seeding rate and row configuration as the whole plot and the other factors as subplots with four replications. The research includes both and evaluation of additive effectives and omission effects.
Silent Shade Corn Production
Presented by: Dr. Richard Turner
Agronomist, Silent Shade Planting Co.
Corn is one of four major crops grown in rotation with cotton on Silent Shade Planting Company in Belzoni, MS. Predicted corn acreage was reduced (1300 acres) when compared to intended (3000 acres) due to lack of favorable planting conditions in the optimum corn planting date window. Efforts are made to optimize yield through use of multiple mode of action herbicide program, adequate planting population, variety placement, proper fertility, tillage, use of fungicide, and nitrogen stabilizer. Average yields will be discussed along with anticipated changes for the 2021 growing season.
Making the Most of Corn Planting Opportunities
Presented by: Dr. Erick Larson
State Corn Specialist, Mississippi State University
Mid-South growers usually have plentiful spring rainfall which limits planting opportunities and stress plant development, but the spring of 2020 was extraordinarily challenging for corn growers. It is also well documented that corn is very responsive to early planting, which puts pressure on us to plant when conditions are far from ideal, or abandon corn growing intentions altogether. However, successfully growing corn depends on numerous factors that interact to ultimately determine the stand, plant health and the resources available to grow a productive and profitable corn crop. We will explain how various factors influence crop development, and offer management recommendations which enhance productivity or reduce risk associated with common limitations and issues encountered in this region.

Glyphosate-Resistant Grass Management in Corn
Presented by: Dr. Larry Steckel
Extension/Research Weed Scientist, University of Tennessee
Presented by: Clay Perkins
Graduate Student, University of Tennessee
Glyphosate has been the primary herbicide in corn to address johnsongrass infestations since the advent of Roundup Ready corn hybrids. However, in recent years University of Tennessee Extension has received numerous reports of johnsongrass, goosegrass and junglerice surviving often multiple applications of glyphosate. In particular, johnsongrass has become more problematic in corn. The beginning of this was in 2015 when populations from Tipton county were found to be 2 to 3 times more resistant to glyphosate than a susceptible population Since 2015, GR johnsongrass has becoming increasingly abundant in many counties across Tennessee. Due to the development of glyphosate resistance, johnsongrass is in the process of becoming the primary weed problem in our state’s corn production once again. Changes in weed management are now clearly needed in corn to address the increasing issues of GR grass weed species.

How to grow 200+ BPA Row Rice without NBPT Urea and only a foot of water
Presented by: Dr. Chris Henry
Associate Professor and Water Management Engineer, University of Arkansas
A novel system has been developed to improve the furrow irrigated rice production system. In 2020 large scale fertigation was attempted at a field level scale to evaluate and demonstrate the potential of using liquid fertilizers and the irrigation system as a fertilizer delivery practice on Ricetec Full Page 7521.Higher yields were achieved when using a plant tissue driven fertigation program. This program was compared to two standard urea programs and two Environmentally Safe Nitrogen programs. Irrigation frequencies of 0-10 days were evaluated and suggests that many are irrigating FIR far too frequently with no yield benefit. The additional benefits of no-till are not impacting yield relative to a tillage production system.

Managed Aquifer Recharge in the US Midsouth: A case study in the design and initial utility of two infiltration galleries in northeast Arkansas
Presented by: Dr. Michele L. Reba
Research Hydrologist, Lead Scientist, USDA-ARS Delta Water Management Research Unit
Presented by: Tom Wimpy
Groundwater levels have been declining in the US Midsouth for decades and can be attributed to overuse from pumping and surface geology. Several water conservation approaches have been taken to reduce groundwater usage and improve water sustainability in the region, especially in Arkansas. In northeast Arkansas where areas where large surface water irrigation projects are not being planned, researchers are evaluating the use of farm-scale manage aquifer recharge(MAR) using infiltration galleries (IG) in conjunction with surface-water storage systems. Low-permeability surface deposits, which greatly limit natural recharge across the region, control the placement of potential IG systems. It is therefore critical to understand the variability of these deposits, as well as underlying aquifer properties, to best plan the placement, design, and operation of such systems. This study aimed to characterize these conditions to assess the feasibility of infiltration galleries in the region. Available well logs were used to map the approximate thickness of surface deposits and identify areas with the thinnest confining unit. Guided by this mapping effort, geophysical and soil surveys were conducted at selected sites. Approximately 37% of the study area, including 28 existing reservoirs that could act as recharge water sources, was identified as having less than 5 m of confining material at the surface. Design of farm-scale IG will be described. Construction of two infiltration galleries began in Fall of 2020. Initial results from this case study will be presented.

Irrigated and dryland corn production under strip-tillage and conventional tillage
Presented by: Dr. Gurbir Singh
Assistant Research Professor Agronomy – Irrigation, Delta Research & Extension Center
Most producers in the Mississippi Delta perform multiple tillage operations before crop planting including subsoiling, and then disking, hipping, and rolling for bed formation. Subsoiling alleviates compaction in deep soil horizons, while surface tillage ensures good soil to seed contact. Conservation management practices that minimize surface tillage while maximizing yield, net returns, and irrigation/fertilizer use efficiency are needed in the mid-southern USA. Strip-tillage with a deep shank can be an alternative practice to the conventional tillage system. Strip-tillage generally disturbs 25% of the plow layer, while the remainder of the soil and surface residues remain undisturbed. Strip-till rigs are designed to band dry or liquid fertilizer using a shank when the tillage operation is performed. Banding fertilizer below the seedbed increases the probability for plant uptake while minimizing loss through runoff. The objective of this study is to quantify the effects of strip-tillage/deep banding P and K fertilizer placement on corn production in irrigated and dryland environments. Strip tillage /deep banding fertilizer placement is compared with surface broadcast fertilizer placement with conventional tillage, and surface broadcast and incorporated fertilizer placement with tillage. Data on corn yield, nutrient uptake, nutrient and water use efficiency, compaction, and soil available P and K from different tillage and fertilizer placement treatments will be reported at the conference.
Practical Irrigation Decisions: Math is greater than emotion.
Presented by: Dan Prevost
Consultant: Southern Ag Services
Proper irrigation is an art. Every farmer knows this because they see the complexities involved with soils and water reflected in the crop every day. This presentation will dive into the basics of soil/water/plant physics and explain these interactions in laymen’s terms. The assumptions made when extrapolating soil moisture sensor data for irrigation decisions will be clearly explained. From that basis, we will transition to volumetric soil moisture sensors and the associated data used to support farm scale irrigation decisions based on a series of mathematical equations.
Row Rice and Cover Crops
Presented by: Keith Scoggins
Farmer/NRCS District Conservationist/Arkansas Soil Health Alliance Member, USDA-NRCS
Presented by: Adam Chappell
Arkansas Farmer: Rice
As production costs associated with rice production continue to rise coupled with current prices, it has become increasingly difficult to maintain a positive margin in Mid-South rice production. Improvements in the production model using cover crops on our farm shave opened the door to explore strategies that have greatly reduced my input costs, while maintaining yields. The ins and outs of 38-inch twin row rice in a cover crop system and impacts on my bottom line will be discussed.
Chappell holds a bachelor’s degree in Botany from Arkansas State University and a master’s degree in Entomology from the University of Arkansas. He raises4,000 acres of soybeans, 2,000 acres of corn, and 1,000 acres each of cotton and rice on about 9,000 acres.
Transitioning to Conservation Management Systems in Corn
Presented by: Dave Spencer
PhD Candidate, Mississippi State University Delta Research and Extension Center
Conservation practices such as cover crops and no-tillage may be useful tools in reducing water use, erosion, and nutrient runoff. However, reported benefits are often based on anecdotal evidence or established conservation systems. The objectives of this research were to investigate the effects of cover crops or no-tillage on yield, profitability, and environmental parameters during a four-year transition period from conventional to conservation management. This presentation will discuss advantages, disadvantages, and changes in the systems over time.
Conservation Tillage Systems for Furrow-Irrigated Soybean
Presented by: Dr. Corey Bryant
Extension Grains Agronomist, University of Georgia, Tifton Campus
Adoption of conservation tillage systems has been limited in the Delta regions of Mississippi due to concerns regarding the functionality of furrow-irrigation practices in these systems. In four-years adoption of a reduced or zone tillage system with or without a cover crop had no negative effects on furrow-irrigation functioning. Soybean productivity and profitability was maintained in reduced tillage systems which included subsoiling or a modified zone tillage system. Use of a cereal rye cover crop did not effect soybean grain yield but did reduce net returns. Conservation tillage systems can be adopted in the Delta regions without having negative effects on soybean productivity, profitability, or furrow-irrigation functionality.

USING ULTRA-HIGH-RESOLUTION DRONE IMAGERY FOR CROP BREEDING HIGH THROUGHPUT PHENOTYPING
Presented by: Dr. Kevin Price, Geospatial Data & Analysis Consultant
Presented by: Don Cummins, President, Air Data Solutions, LLC
“The essence of biology is to understand the link between genotypic and physical (phenotypic) characteristics. Reflecting this, the primary focus of plant genetics research since the discovery of DNA has been to understand how DNA polymorphisms impacts a plant’s phenotype. Making this connection is central to plant biology, ecology, population genetics, and plant breeding. To connect DNA to phenotypes on a genome-wide scale and understand the genetic architecture of complex traits on a species-wide level, large populations must be reliably phenotyped and genotyped. This level of biological understanding will greatly expand the field of plant biology while helping meet the challenges of increasing food, feed, and fiber production in the face of growing populations, decreasing land area and changes in climate.
The bottleneck to plant breeding is phenotyping. For this reason, there is a need for robust, high-throughput phenotypic (HTP) methods for assaying a range of traits in crops within a field growing condition. Remote sensing is the most promising approach for developing a low-cost, flexible methods amendable to a range of plant species” (Poland et al. 2012).
During this presentation, we will discuss how ultra-high-resolution color infrared imagery acquired from a drone aircraft is acquired and used by generic breeders to identify key plant growth characteristics of significance to plant breeding objectives.
