Irrigated potato rotation research in Manitoba
Increasing demand for potatoes from Manitoba, mostly from the expanding french fry processing industry, has increased the need for acreages suitable for irrigated potato production. That need can be met by bringing additional land into potato production, and by increasing the frequency of potatoes in rotation with other crops on existing potato land. The first option is limited by the suitability of soils, the high cost of irrigation equipment, and the availability of water for irrigation. However, increasing the frequency of potatoes in rotation with other crops raises important concerns about soil sustainability, buildup of pests (diseases, insects, weeds), and potential contamination of surface and groundwater by fertilizer and pesticides. The objective of this study was to determine the effect of crop rotation and rotation length on potato yield and quality, disease incidence, weed ecology, and soil chemical, physical and biological properties.
