Zhang J., 2026, A practical field-based method for improving potato yield and tuber uniformity through optimized planting density, Genomics and Applied Biology, 17(1): 51-60 (doi: 10.5376/gab.2026.17.0005)

In many production areas, potatoes are not only a staple food but also an important source of income. Whether they are grown well or not directly affects the yield and stable production. However, in actual production, simply planting more does not necessarily lead to higher yields. Planting density often influences the field population structure, yield level, and uniformity of tubers. Appropriate density arrangement can often increase the yield per unit area without additional input and make the tubers more uniform in size. However, if planted too densely, competition for light, water, and nutrients becomes more intense, reducing the tuber-setting ability of individual plants, increasing the number of small and deformed tubers, and deteriorating the commercial quality. Based on these practical issues, comparing different densities through field experiments, summarizing the corresponding management experiences, and analyzing specific cases can provide more practical references for high-yield and high-quality potato cultivation under different ecological conditions.
