The Application of Fulvic Acid Can Enhance the Performance of Rice Seedlings Under Low-Nitrogen Stress.

ABSTRACT: Fulvic acid's potential to enhance plant growth has been recognized, but its effects on plant growth and nutrient uptake under nutrient stress remain unclear. This experiment investigated the effects of fulvic acid at concentrations of 0 mg L^-1 (T1), 30 mg L^-1 (T2), 60 mg L^-1 (T3), 90 mg L^-1 (T4), 120 mg L^-1 (T5), and 150 mg L^-1 (T6) on the growth performance of two rice varieties-Jikedao 654 (J 654) and Jiyang 100 (J 100)-under low-nitrogen stress in a hydroponic system. The effects of different fulvic acid application rates on the growth and photosynthetic characteristics, the key enzymes of nitrogen metabolism, antioxidant properties, and the osmotic adjustment substances of rice under low-nitrogen stress were evaluated.
