Project Number: 1915-62660-002-01
Project Type: Specific Cooperative Agreement

Start Date: Sep 01, 2007
End Date: Dec 30, 2008

Objective:
The objective of this project is to evaluate the effects of selected rotation crops on multiple soilborne diseases, tuber yield and quality, and economic viability.

Approach:
The research will consist of replicated field trials conducted on-farm and at research sites with a history of powdery scab or other soilborne diseases. Previously, field trials were established at multiple locations, where multiple two-year rotations were established with up to six different Brassica rotation crops (canola, rapeseed, condiment mustard, oriental mustard, oilseed radish, and a high-glucosinolate mustard blend) and compared to a standard rotation crop control (barley, buckwheat). Effects on the subsequent potato crop, including in-field disease assessments and tuber symptoms, tuber yield, and tuber quality will be evaluated. Economic analyses of the rotation sequences will also be conducted to determine the effects on profitability and risk.
