Intervention effect CRU improved rice grain yield over conventional urea at the same nitrogen level.
Intervention effect CRU improved NUE over conventional urea at the same nitrogen level.
Intervention effect Reducing CRU nitrogen by 40% still gave higher rice yield than full conventional urea.
Intervention effect Reducing CRU nitrogen by 40% gave higher net profit than full conventional urea.
Intervention effect ZNC increased rice panicle number.
Intervention effect ZNC increased nitrogen accumulation in rice.
Intervention effect ZNC increased rice yield.
Intervention effect ZNC enriched CRU increased rice grain yield by 9.2% in one year.
Intervention effect ZNC enriched CRU increased rice grain yield by 8.7% in the other year.
Intervention effect ZNC increased rice NUE and N partial factor productivity.
Intervention effect ZNC increased net profit.
Recommendation The authors conclude that combining CRU and ZNC can reduce nitrogen input while maintaining yield.
