Brief Project Summary:

Soybean Cyst Nematodes (SCN) are major soybean pest and are responsible for extensive crop and economic losses. Effective management strategies are limited for this pest with the two most common options being crop rotation and the use of resistant varieties. Despite the effectiveness of available resistant varieties, there is a lack of diversity in the source of resistance. Repeated use of a single resistance source can result in SCN populations that overcome the resistance. The objectives of this study is to compare sources of resistance on SCN reproduction, the use of poultry manure on populations of SCN when applied during non­ host years of crop rotation.

Information And Results
Project Deliverables

To investigate the effects of poultry manure on H. glycines abundance, two tons of chicken manure will be applied per acre before corn is planted in 2017. Manure will be applied in 18.2 m strips. In total, four rows will be applied with manure and four rows untreated (two treatments with four replications per treatment). The two treatments will be in alternating rows. Soil samples will be taken before manure is applied, 2-3 weeks after application, and a third sample will be taken near harvest. Soil samples will be taken from each replication as composite samples. Fields will be sampled in a zigzag pattern in order to reduce variability. Nematodes will be extracted and counted from the samples.

Final Project Results

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.
