2. Important Considerations in
Rubber Production:
 Selection of good clone/s
 Product of High Quality Young Rubber Planting
Materials
 Proper establishment and management practices
 Latex harvesting technique
 Proper postharvest practices

3. Nursery
A specially established area or location where plants
are nursed and raised for later field planting.
It offers the advantages of producing large and
uniform number of good and healthy planting
materials.
