Brief Project Summary:

This is an integrated research, education, and demonstration project helping Missouri producers validate management decisions on their farm and document efficiency and environmental stewardship. In collaboration with the Iowa Soybean's On-Farm Network, pursue these goals: (1) Provide Missouri farmers access to a trial focused on ILeVO, and (2) Gain insight into how On-Farm Network runs trials as a first step in defining opportunities for closer collaboration between the two programs.

This project addresses the emphasis area of "improving soybean management practices through research and demonstration."

Information And Results
Project Deliverables

Work with MU extension specialists to identify 12 farmers interested in the trial. Farmers will be responsible for planting the trial with the technical support of MU Extension. Prior to planting and after harvest, each strip will be soil sampled
(minimum 20 cores per sample) and analyzed for SCN count using the MU SCN Diagnostic lab. Additionally, an HG type test of a composite, end of season soil sample will be conducted on all fields.

MU Extension will obtain at least one aerial photo of the field during the growing season. MU Extension and the farmer will monitor the field through July and August identifying fields in the trial where SOS symptoms are observed. Farmers will get a report summarizing the outcome from the trial on their farm.

The MU campus team will take farm-specific results and integrate those results across locations and years while protecting the identity of participating farmers. Summary data from the trials will contribute to improvements in MU recommendations and provide all partners information on the efficiency of Missouri farmers.

The key results of the trial were:
1. ILeVO increased yield in the Missouri trials. On sites with SDS there was a 50% chance of a response of 3.9 bushels per acre or more. On sites with no SDS, there was a 50% chance of a response of two bushels per acre or more.
2. There was evidence that the high ILeVO rate reduced the SCN reproductive factor; the effect of ILeVO was greater at locations with higher SCN reproduction.
3. In Iowa, there was no evidence that ILeVO increased yields on fields with SDS and the potential response on other fields was less than on Missouri fields.
This on-farm research documents the importance of testing management practices locally.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
