In rice paddies of Vietnam's tropical delta, ECOGANIC NANOTECHNOLOGY increased yield by +16.1% (6,400 → 7,430 kg/ha) and raised the percentage of filled grains from 74% to 85% with 3 foliar applications.
The trial: rice in Vietnam's tropical delta
Vietnam is the world's second-largest rice exporter, cultivating short-cycle indica varieties (90-110 days) in the Mekong Delta and Red River Delta. High-temperature conditions (30-36 °C at flowering), elevated humidity, and intensive cropping cycles create particular challenges for maximizing the percentage of filled grains — a key parameter for export price.
The trial evaluated ECOGANIC NANOTECHNOLOGY in commercial short-cycle rice paddies under irrigation, applying the biostimulant at 3 critical growth stages and comparing it with an untreated control under the same standard mineral fertilization program.

Why nanotechnology biostimulants are especially effective in short-cycle rice
In short-cycle varieties with 2-3 harvests per year, the margin for error in each phenological window is minimal: any nutritional deficit or stress during the 15-20 days of panicle initiation-flowering translates directly into yield losses with no possibility of later recovery. Nanotechnology enables a faster response than conventional fertilizers because submicron particles actively cross the leaf cuticle.
- Foliar absorption in hours: Nanoparticles penetrate in less than 6 hours after application, compared to 24-48 hours for conventional chelates—a critical factor when the useful window between two tropical rains is short.
- Stimulation of chlorophyll synthesis: Maintains a high foliar SPAD index even under high temperatures, ensuring carbohydrate production for grain filling.
- Pollen protection under water/heat stress: The activation of protective osmolytes (proline, betaine) improves pollen grain viability above 35 °C.

Frequently asked questions about biostimulants in rice in Vietnam
How many crops per year can be treated with this protocol?
The 3-application-per-crop protocol is fully compatible with systems of 2 or 3 annual harvests. The product does not accumulate residues in soil or irrigation water, so it can be applied in all crops without additional restrictions.
Is it compatible with the insecticides and fungicides commonly used in tropical rice?
ECOGANIC NANOTECHNOLOGY is compatible with the main fungicides and insecticides authorized in rice. It can be mixed in the tank with trifloxystrobin, azoxystrobin, or imidacloprid without losing efficacy. It is recommended to always perform a small-scale compatibility test with new products.
Are the results transferable to aromatic varieties such as Jasmine or Basmati?
The trial covers standard short-cycle indica varieties. In aromatic varieties such as Jasmine or Thai Hom Mali, the mechanism of action is the same, but the application protocol must be adapted to avoid compromising the aromatic profile — in particular, it is recommended not to apply during the heading-late flowering stage to preserve the synthesis of 2-AP (aromatic molecule). Consult with your technician before extrapolating.
