The general goals of this project are to determine factors influencing soybean seed germ and vigor test results, correlation with field emergence under Arkansas conditions, and to educate Arkansas producers about seed quality and vigor testing. The project’s specific objectives are to: • Determine the correlation of the standard germination test, AOSA-recommended accelerated aging vigor test, a cold temperature vigor test, and the SVIS vigor test system with emergence, survival and yield of selected soybean seed lots (of varying quality and vigor) under growth chamber and field emergence stress environments; • Survey and test different soybean seed lots in Arkansas over time and in different storage environments (controlled and real world) and compare using standard germination tests, AOSA-recommended accelerated aging vigor testing, a cold temperature vigor test and the SVIS vigor test; • Evaluate selected seed treatments on seed lots representing a range of seed vigor; • Determine the effect of seed disease resistant cultivars or breeding lines and the use of very late season foliar fungicides on seed quality (vigor); • Evaluate soybean germplasm for potential to produce seed with high germability and vigor using standard germination, accelerated aging vigor, cold vigor and SVIS vigor tests under Arkansas production conditions; and • Develop and deliver a sustained education program focused on soybean planting seed quality and seed vigor testing in Arkansas to soybean growers and the soybean industry.
