Summary
This 2024 field study investigates optimal macronutrient ratios of nitrogen, phosphorus and potassium in potato production, with emphasis on how balanced fertilisation affects both agronomic yield and biochemical quality traits. The authors present evidence that appropriate NPK combination enhances enzymatic and antioxidant defence systems in potato plants, as suggested by the mechanistic focus on oxidative stress pathways. The findings contribute to understanding nutrient management strategies that simultaneously optimise productivity and nutritional quality in potato cropping.
Regional applicability
Potato production in the UK operates under different soil conditions, climatic patterns and regulatory frameworks (including nutrient management regulations) than likely study sites in China; however, the principles of balanced macronutrient application and quality-yield trade-offs are broadly transferable to UK horticulture. UK growers may benefit from the enzymatic insights, though local soil testing and variety-specific responses would require validation.
Key measures
Plant yield, tuber quality parameters, enzymatic activity, antioxidant enzyme activity, nutrient composition
Outcomes reported
The study examined how balanced nitrogen, phosphorus and potassium application influences potato plant yield, tuber quality attributes, and biochemical markers including enzymatic and antioxidant activities.
