What it does

Poorly transplanted plants have inadequate plant stand.

Why and where it occurs

It becomes a problem when labor is limiting.

How to identify

Poorly transplanted field have inadequate or uneven plant stand (e.g., plants are too far apart or missing).

This should not be confused with factors affecting crop stand (e.g., low seed rate, or poor seed distribution), pest damage during establishment (e.g., rats, birds, snails or possibly crabs).

To confirm the cause of problem, check or ask farmer about planting practices.

How to manage

• For good establishment, shift to mechanized transplanting or direct seeding if labor supplies are inadequate
• Manage water and ensure well leveled water, ensure an appropriate seed rate with even distribution of seed
• Crop stand should be of the order of 100 to 200 plants per m2, use seed rates between 40 to 100 kg per ha if other factors (e.g., pest problems and seedbed preparation) are not problematic
