This document provides guidelines for improving rubber yield through best practices in rubber production. It recommends: 1. Good land preparation including suitable density planting of 7x3 meters. 2. Using high quality varieties and maintaining good soil fertility through amendments, organic and chemical fertilizers tailored to soil type and tree age. 3. Regular foliar feeding and soil treatments including chitosan which has antimicrobial properties and boosts the plant's defenses against viruses. Working with specialists can help farmers implement these practices and supply necessary materials to increase productivity and meet rubber yield targets.

9. Foliar application
Adds chitosan 5-10 ml blends with BE foliar
50 ml/20L spray to the rubber seedling, stem, or
rhizosphere soil for every 1-2 months.

10. Why Chitosan?
Oligopolymer

11. Antimicrobial, against viruses
[inhibit the systemic propagation of
viruses and viroids throughout the plant
and to enhance the host’s hypersensitive
response to infection]
Benefit of Chitosan

13. How to meet the target with us?
1. Research collaboration (consultant).
2. Supplies materials such as fertilizer, soil
amendments, foliar, chitosan and tapping
treatment substance.
