Identity before method
Shiitake
Lentinula edodes
- Taxonomy note
- Cultivated Lentinula edodes with log and supplemented-block methods kept separate.
- India readiness
- developingIndian institutional methods and varieties exist, while infrastructure, strain, maturation and market fit require project-specific validation.
- Method difficulty
- advanced
- Casing
- no
- Production systems
- natural log; sterilized sawdust block
- Post-harvest
- Fresh and dried channels have distinct maturity, handling and process-control requirements.
Production method records
One species can require more than one cultivation model.
