Implication

Field experiment demonstrates improved yield and nitrogen efficiency in low-gluten wheat under blended controlled-release urea, indicating an effective fertilization strategy.

Key Points

To evaluate the effects of common urea, controlled-release urea, and their combination on grain yield, quality, nitrogen use efficiency, and soil nitrogen dynamics in low-gluten wheat.
Conducted a two-year field trial (2023–2024) testing three nitrogen fertilization strategies: 100% common urea (CU100), 100% controlled-release urea (CRU100), and an 80:20 ratio of controlled-release to common urea (CRU80CU20).
Evaluated agronomic endpoints including grain yield, spike grain count, dry matter accumulation, grain protein content, and nitrogen use efficiency (NUE) alongside structural path analysis.
Compared with CU100, CRU80CU20 increased grain yield by 19.2% in 2023 and 23.3% in 2024, while CRU100 increased yield by 8.51% in 2023 and 14.3% in 2024.
CRU80CU20 produced the highest nitrogen use efficiency and significantly reduced grain protein content, linked directly to improved dry matter accumulation and higher grain counts per spike.
