The 2022 Soybean Research Verification Program (SRVP) was conducted on 17 commercial soybean fields across the state. Counties participating in the program included Arkansas, Ashley, Chicot, Conway, Desha, Drew, Greene, Independence, Lawrence, Lee, Lonoke, Mississippi, Monroe, Poinsett, St. Francis, White, and Woodruff for a total of 1,079 acres. Grain yield in the 2022 SRVP averaged 65.5 bu./ac, ranging from 37.3 to 88.0 bu./ac. The 2022 SRVP average yield was 13.5 bu./ac, greater than the estimated Arkansas state average of 52 bu./ac. The highestyielding field was in Desha County, with a grain yield of 88 bu./ac. The lowest yielding field was in Independence County and produced 37.3 bu./ac. [ABSTRACT FROM AUTHOR]

The 2021 Soybean Research Verification Program (SRVP) was conducted on 19 commercial soybean fields across the state. Counties participating in the program included Arkansas, Chicot, Clay, Conway, Cross, Desha, Drew, Faulkner, Independence, Jefferson, Lafayette, Lawrence, Lee, Mississippi, Perry, Poinsett, St. Francis, White, and Woodruff, for a total of 1170 acres. Grain yield in the 2021 SRVP averaged 62.6 bu./ac ranging from 30.1 to 78.0 bu./ac. The 2021 SRVP average yield was 11.6 bu./ac, greater than the estimated Arkansas state average of 51 bu./ac. The highest yielding field was in Desha County, with a grain yield of 78 bu./ac. The lowest yielding field was in Perry County and produced 30.1 bu./ac. [ABSTRACT FROM AUTHOR]

The 2020 Soybean Research Verification Program (SRVP) was conducted on 17 commercial soybean fields across the state. Counties participating in the program included; Arkansas (2), Clay, Cross, Desha, Drew, Faulkner, Jackson, Jefferson, Lafayette, Lee, Monroe, Perry, Poinsett, Randolph, White, and Woodruff for a total of 919 acres. Grain yield in the 2020 SRVP averaged 65.1 bu./ac ranging from 34 to 75.2 bu./ac. The 2020 SRVP average yield was 15.1 bu./ac greater than the estimated Arkansas state average of 50 bu./ac. The highest yielding field was in Arkansas County, with a grain yield of 75.2 bu./ac. The lowest yielding field was in Faulkner County and produced 34 bu./ac. [ABSTRACT FROM AUTHOR]

The 2018 Soybean Research Verification Program (SRVP) was conducted on 21 commercial soybean fields across the state. Counties participating in the program included; Arkansas, Ashley, Chicot, Clark, Clay, Conway, Crawford, Crittenden, Cross (2), Desha (2), Greene, Jackson, Jefferson, Lincoln, Lonoke, Miller, Randolph, St. Francis and Washington Counties for a total of 1277 acres. Grain yield in the 2018 SRVP averaged 62.8 bu./ac ranging from 34.2 to 83.5 bu./ac. The 2018 SRVP average yield was 12.8 bu./ac greater than the estimated Arkansas state average of 50 bu./ac. The highest yielding field was in Clark County with a grain yield of 83.5 bu./ac. The lowest yielding was in Jackson County and produced 34.2 bu./ac. Due to extremely delayed harvest and subsequent unfavorable weather conditions, Miller County was deemed unmarketable and is not included in average yield. [ABSTRACT FROM AUTHOR]

Economic and agronomic results of a statewide soybean research verification program can be a useful tool for producers making production management decisions before and within a crop growing season. The 2018 season results provide additional economic relationship insights among seasonal, herbicide, and irrigation production systems. Early-season production system fields had approximately 15% higher yields and 25% higher net returns than full-season system fields. Roundup Ready® (RR) herbicide production system fields had a 5 bushel per acre yield advantage over LibertyLink® (LL) system fields, but the field groups were virtually equal in net returns. Irrigated versus non-irrigated system comparisons indicated equal yields. Lower total cost levels associated with non-irrigated system fields gave them a 29% higher net return per acre. Early-season irrigated production systems had yields and net returns equivalent to non-irrigated fields, but full-season irrigated were lower in both respects. [ABSTRACT FROM AUTHOR]
