Controlled-release fertilizers increase sunflower yield by regulating soil nitrogen, photosynthesis, and root structure in arid regions
CRF improved nitrogen synchrony, yield, and NUE under arid irrigation. The 225 kg N/ha CRF rate provided the most favorable yield-efficiency balance, offering a practical management strategy for sustainable production in water-limited regions. By quantitatively linking CRF to soil-root-plant nitrogen coordination, this study advances understanding of nitrogen optimization in arid irrigated systems.
