Interplanting wheat in paddy fields instead of conventional drilling, along with using nitrogen fertilizer, affects the grain yield and quality of weak gluten wheat. Interplanting wheat in paddy increases starch content but decreases grain yield and protein content. Nitrogen fertilizer boosts grain yield and protein content but doesn't improve special quality in weak gluten wheat. Interplanting wheat in paddy can balance quality and yield with specific nitrogen levels and application timings.
