This study addresses the low yield and fertilizer utilization efficiency of potatoes in arid region Xinjiang, Northwest China. The effect a novel, fulvic acid-based specialized for drip application on potato growth, development, yield, is investigated. aim to identify suitable formula cultivation Xinjiang promote its demonstration application, providing theoretical basis improving achieving stable, high yields region. experiment was conducted with variety 'Xisen 6' using field trial design, which included five treatments: no (CK), conventional (CF: N-P-K = 258-245-338 kg·ha-1), formulated 1 (F1: 120 g·L-1 acid, 110-100-120 g·L-1), 2 (F2: 60 130-120-150 3 (F3: 30 170-150-130 g·L-1). Agronomic traits, gas exchange parameters leaves during tuber expansion stage, components at harvest were measured, along use each treatment. Results show that F1, F2, F3 improved plant height, stem diameter, aboveground dry weight, SPAD value, stomatal conductance (Gs), yield. Among these, F2 significantly enhanced accumulation relative chlorophyll content (SPAD value) increased photosynthesis, further efficiency, resulting increase 121.29% 34.6% compared CK CF, respectively. Therefore, identified as optimal fertilization strategy Xinjiang. Its has been extended trials. Field results 14.79% CK, proving effectiveness replacing fertilizers enhancing production.
