Effects of nitrogen application on potato (Solanum tuberosum L.) yield and soil nitrate dynamics in a sandy loam soil
Nitrogen (N) is a crucial nutrient for potato (Solanum tuberosum L.) production, but excessive application can lead to environmental degradation and reduced nitrogen use efficiency (NUE). This study evaluated the effects of different nitrogen application rates (0, 60, 120, 150, 180, 210, and 240 kg N/ha) on tuber yield, nitrogen uptake, and soil nitrate accumulation over two growing seasons. The results showed that the highest tuber yield (20.8 t/ha) was obtained at 150 kg N/ha, beyond which further increases in nitrogen application did not result in significant yield improvements (P
