Three formulations. One per rice growth phase. Built around native Mekong strains, refined across more than two thousand hectares of trial. The biology behind the Long Phú case — and the line that defined what Nam Phương does.
Rice does different things at different times. We respect that. Each formulation does one job, well, on its window. Used together, they replace 30 — 40% of synthetic input demand across a season.
Every microbe in the Nap 2Rice line was isolated from healthy rice paddies in the Mekong delta — not licensed, not imported. The strains have grown up here. They know the work.
Three biological actives — present in different ratios across the three formulations.
· Bacillus consortium — soil colonisers. Nitrogen fixation, phosphorus solubilisation, root zone defence. Six strains, all native isolates.
· Trichoderma + Pseudomonas — fungal-bacterial pair for root health. Suppresses common rice soil pathogens. Builds the rhizosphere.
· Plant-derived polyphenols + enzymes — extracted from local botanical sources. Stress signalling, grain-fill enzymes, antioxidant function.

A 90 — 100 day rice season, with the three formulations placed on their proper windows. This is what we recommend to working farmers — and what was used in the Long Phú trial.
Total Nap 2Rice cost per hectare per season — roughly equivalent to 30% reduction in synthetic NPK + bio package. Net farmer benefit at Long Phú: +35 m₫ / ha / season.
4.2 hectares in Sóc Trăng province. Side-by-side trial against a conventional control plot. Witnessed by Cần Thơ University agronomists. Three full rice seasons of measurement.
+40% yield · +25% farm-gate price · −32% input cost.
