Optimum age of seedlings for quick establishment :
1. Optimum age of the seedlings is 18-22 days for short, 25-30 days for medium and 35-40 days for long duration varieties.
Pulling out the seedlings :
1.Pull out the seedlings at the appropriate time (4th leaf stage).
2. Pulling at 3rd leaf stage is also possible. These seedlings can produce more tillers, provided enough care taken during the establishment phase (See section 1.8 Integrated Crop Management (ICM) - Rice-SRI) through thin film of water management and perfect leveling of main field.
