This change implies the expected duration of the state's growing season in 2008 was nearly 16 days longer than in 1879.

ESPS early soybean production system MG maturity group PD planting date 1 INTRODUCTION In 2023, Arkansas's soybean farmers produced 159.3 million bushels of soybean (Glycine max L.) crop, with an estimated production value is $2.08 billion, and the state is ranked 10th in soybean production (USDA-NASS, 2024). The state is also ranked 10th in soybean export, valued around $1.27 billion in 2022 (USDA-ERS, 2023).

By Bayarbat Badarch and Brad Watkins Rice planting can be very stressful during the spring in Arkansas and across the rice belt, as weather greatly affects the timing of planting. Extreme weather events like excessive spring rainfall and cooler-than-average temperatures can reduce the number of days available for planting rice early. Excessive rainfall and flooding events have delayed the timing of rice planting in Arkansas in three of the last four years (2022, 2020, 2019).
