Title

Effect of rice-duck co-cultivation on the trend of changes in growth indices, photosynthesis and irrigation and precipitation water productivity in different cultivation systems

Kamran Mansour Ghanaei-Pashaki; Golam Reza Mohsen abadi; Mohammad Hassan Bigluei; et al. DOAJ (DOAJ: Directory of Open Access Journals) 2022. doi:10.22034/saps.2021.44833.2646

Other claims from this paper (3)

Intervention effect At the beginning of growth, crop growth rate was slower in SRI than other systems.
Observation From middle to late growth, crop growth rate ranked SRI above IC above CC.
Recommendation The authors considered rice-duck systems suitable for improving rice yield and growth indicators.
