Abstract

The effects of NPK fertilization levels on soil chemical properties, plant growth and nutrient use efficiency were evaluated in cultivated wild chive (Allium monanthum Maxim.). Cultivation experiments were conducted over two years (2023－2024) at five fertilization levels (0×, 0.5×, 1.0×, 1.5×, and 2.0×) based on the standard rate of 111-67-107 kg･ha-1 (N-P2O5-K2O). Additionally, a fertilizer use survey was conducted on 41 major cultivation farms. The survey revealed that available phosphate and exchangeable potassium levels in many cultivated soils tended to exceed the recommended ranges. In the cultivation experiment, fertilization exceeding the standard rate reduced dry matter yield, whereas the maximum yield was achieved at 79-113-90 kg･ha-1 (N-P2O5-K2O), as revealed by regression analysis. The highest crop productivity and nutrient use efficiency were observed at 0.5-1.0× the standard fertilization rate. Fertilizer use efficiency indices (FPFP, FAE, and FR) were also highest within this range. These results indicate that rational fertilizer management can help maintain soil nutrient balance and promote sustainable cultivation of wild chives.
