Potato Trials Show Little Benefit From Nue Products
GuideDelegateMaritimeIrrigation And Drainage
Executive Summary
AI-generatedIndependent research conducted through the Cupgra Reference Crop program found that Nitrogen Use Efficiency (NUE) products provided no measurable benefit to potato yields in 2025. The trial demonstrated that while yield increased significantly with higher rates of applied nitrogen, adding these specialized NUE products did not improve results at either tested rate. Researchers suggest the timing of nutrient uptake is a key factor for growers to consider.
Key Insights
- The 2025 Cupgra Reference Crop trial found that various Nitrogen Use Efficiency (NUE) products offered no practical yield improvement for potatoes.
- Yield increases were observed only when comparing the low nitrogen rate (90kg/ha) to the optimal high rate (220kg/ha), regardless of NUE product use.
- The study concluded that the NUE products either supplied negligible amounts of nitrogen or provided no additional benefit measurable in a practical way.
- Potatoes are noted for rapidly absorbing nitrogen shortly after emerging, which presents a challenge for nutrient management timing.
