Project Number: 6402-21000-034-02
Project Type: Specific Cooperative Agreement

Start Date: Aug 22, 2006
End Date: May 31, 2011

Objective:
Optimize management practices for production of early-maturing soybean in Mississippi. Evaluate foliar fungicides for control of Asian rust and other late-season diseases. Determine impact of defoliation on yield of determinate and indeterminate soybean. Optimize wheat/soybean double cropping system.

Approach:
Maturity Group III, IV and V soybean varieties will be planted at different dates and seeding rates to determine optimum seeding rates for specific planting scenarios. Fungicides will be evaluated as single and sequential applications at various locations. Determinate and indeterminate varieties will be used. A spray as necessary treatment will be compared with applications of different classes of fungicides applied at different reproductive stages of soybean. Various percentage of foliage will be removed manually from bottom of plants at different reproductive stages of soybean to emulate effect of rust infection. Maturity group III, IV and V soybean varieties will be planted following wheat and this sysem will be compared to full season soybean in the Early Soybean Production System.
