This past season marked the 21st year of the Arkansas Soybean Research Verification Program (SRVP), an Extension program funded through Arkansas' soybean check-off. Since its inception over 400 producers have participated in the SRVP. The primary goal of the SRVP, among others, is to conduct on-farm field trials to verify research-based Extension production recommendations developed by the Agriculture Experiment Station. In 2004, 19 producers in 18 counties enrolled in the SRVP. Extension recommendations for soybean production were followed from variety selection through harvest. The program consisted of 12 irrigated and 7 non-irrigated fields. Production systems represented included early season non-irrigated, full season irrigated, full season non-irrigated, and double-cropped irrigated. Weekly field visits by the producer, county agent, and SRVP coordinator allowed close monitoring of the crop's progress. Decisions with regard to irrigation scheduling, pest management, and fertility were made based upon Extension recommendations. Average yield in the 2004 SRVP was 49.0 bu/ac and 48.8 bu/ac for irrigated and non-irrigated fields, respectively. The Arkansas soybean yield average in 2004 was 43.0 bu/ac and 34.0 bu/ac for irrigated and non-irrigated fields, respectively. Irrigation timing and pest management decisions are the two areas in which producers indicate the SRVP has the most impact.
