Foxtail millet is an important cereal crop in the North China Plain. However, excessive nitrogen fertilizer application over years has led to declining yield and soil quality. This study investigated nutrient management strategies for foxtail based on levels availability. In a field where targeted fertilization was conducted six seasons, effects dynamics of soil-available were monitored continuously two consecutive (2022–2023) across five different varieties with varying levels. The aimed determine optimal rate achieving high millet, minimum nitrate threshold required maintain fertility, effective range sustaining Results showed that significantly affected dry matter weight during flowering, while variety at maturity. average all 141.3 kg·ha−1. Specifically, nitrogen-efficient (5607.32–5637.19 kg·ha−1) 151.5 kg·ha−1, nitrogen-inefficient (4749.77–4847.74 134.5 Soil NH4+-N NO3−-N content increased when exceeded 360 posing environmental risks. To achieve yield, would be maintained 17.23 mg·kg−1 (before sowing) 9.75 (at maturity). A relationship between established: y = 867.5 − 50z (where represents (kg·ha−1), z 0–20 cm layer before sowing, ranging from 10.0 17.35 mg·kg−1), which provided practical method millet. this study, strategy optimized according level targets, controlled within kg·ha−1 content, will instructive reducing use, maximizing efficiency, increasing yield.
