Our Focus Areas
Research programs and priority topicsThe Research Division provides evidence-based solutions for crop, livestock and forestry challenges — from trials to farmer-ready recommendations, seed and planting material evaluation, pest & disease monitoring, and climate-resilient systems.
Crop Varieties & Trials
On-station and on-farm trials for improved crop varieties (cassava, root crops, vegetables, fruit trees) and yield optimization.
Soil & Nutrient Management
Research on soil health, integrated nutrient management, composting, and fertilizer packages appropriate to Tonga soils.
Pest & Disease Surveillance
Monitoring, diagnostics and management strategies for pests and diseases affecting crops and livestock.
Livestock & Animal Science
Breeding, nutrition, veterinary practices and production systems to improve meat, dairy and poultry productivity.
Forestry & Agroforestry
Agroforestry systems, native timber and fruit tree improvement, and planting protocols for coastal resilience.
Climate-smart Systems
Developing climate-smart cropping systems, water-efficient techniques and coastal adaptation measures.
