Arkansas is the leading soybean-producing state in the mid-southern United States. Arkansas ranked 11th in soybean production in 2022 when compared to the other soybean-producing states in the U.S. The state represented 3.04% of the total U.S. soybean production and 3.64% of the total acres planted in soybean in 2022. The 2022 state soybean average yield was 52.0 bushels per acre, tying the previous state yield record of 52 bushels per acre set in 2021. The top five soybean-producing counties in 2022 were Mississippi, Crittenden, Phillips, Poinsett, and Arkansas (Table 1). These five counties accounted for over 35.7% of the soybean production in Arkansas in 2022.

Weather events during the early portion of the 2022 growing season were wetter compared to those during 2021. Frequent rain events hampered preplant tillage and delayed planting for some portions of the state. Soybean planting during 2022 was delayed compared to the previous year and behind the 5-year average for planting progress until mid-March. Weather conditions improved by mid-March, and planting progress met and surpassed the 5-year average for planting progress for the remainder of the planting season. According to the 5 June 2022 USDA-NASS Arkansas Crop Progress and Condition Report (USDA-NASS, 2022), 86% of the soybean acreage had been planted as of the first of June compared to 85% and 79% for the 2021 and the 5-year average planting progress, respectively. With higher commodity prices, Arkansas soybean producers planted 3.18 million acres in 2022. This was an increase in acreage compared to 2021, and back to over 3 million acre planted for the last two years. The most significant event to occur in Arkansas during the 2022 growing season was the abnormally hot and dry conditions during June and July. Preface The 2022 Arkansas Soybean Research Studies includes research reports on topics pertaining to soybean across several disciplines from breeding to post-harvest processing. Research reports contained in this publication may represent preliminary or only data from a single year or limited results; therefore, these results should not be used as a basis for long-term recommendations. Several research reports in this publication will appear in other University of Arkansas System Division of Agriculture’s Arkansas Agricultural Experiment Station publications. This duplication is the result of the overlap in research coverage between disciplines and our effort to inform Arkansas soybean producers of the research being conducted with funds from the Soybean Check-off Program. This publication also contains research funded by industry, federal, and state agencies. Use of products and trade names in any of the research reports does not constitute a guarantee or warranty of the products named and does not signify that these products are approved to the exclusion of comparable products. All authors are either current or former faculty, staff, or students of the University of Arkansas System Division of Agriculture, or scientists with the United States Department of Agriculture, Agriculture Research Service. Extended thanks are given to the staff at the state and County Extension offices, as well as the research centers and stations; producers and cooperators; and industry personnel who assisted with the planning and execution of the programs. Acknowledgments Most of the research results in this publication were made possible through funding provided by the soybean producers of Arkansas through checkoff monies and administered by the Arkansas Soybean Promotion Board. We express sincere appreciation to the soybean producers and the members of the Arkansas Soybean Promotion Board for their vital financial support of these programs.

Overall, disease and insect issues were at typical levels in 2022. The exception was in the southern part of the state where Redbanded stinkbug were detected in fields earlier than in past few years and their numbers remained high throughout harvest. Most soybean-producing counties in Arkansas have some level of Palmer amaranth that has multiple herbicide resistance, and soybean production in these fields is becoming very difficult due to the loss of many herbicides. The 2022 growing season was the sixth year where the use of dicamba was labeled for over-the-top applications on dicamba-tolerant soybean. Even with restriction on applications, complaints were filed with the Arkansas State Plant Board for non-dicamba soybean fields showing dicamba symptomology.
