What question did this study set out to answer?

The aim is to enhance yield and nitrogen use efficiency in rice via optimized cultivation models under long-term straw return.

High yield and efficient use of nitrogen in rice under long-term straw return could be achieved by increasing planting density and reducing blended controlled-release nitrogen

The aim is to enhance yield and nitrogen use efficiency in rice via optimized cultivation models under long-term straw return.
Conducted field experiments in Northeast China during 2023-2024
Tested two planting densities (D1 and D2) and two nitrogen fertilizer types (urea and controlled-release)
Evaluated four nitrogen levels ranging from 0 to 175 kg/ha
Monitored crop growth rate, net assimilation rate, and biomass transport ratios.
D2CRUN2 achieved a 16.43% increase in yield compared to D1UN3
Increased panicles per square meter by 16.07%
Enhanced crop growth rate and nitrogen use efficiency by over 54% under optimal conditions
Significantly boosted net profit by 38.05% with D2CRUN2 compared to baseline.
