This Vietnamese rice study revealed that Vitazyme applied three times — an hour before sow- ing, 30 days after sowing, and 50 days after sowing, each time at liter/ha — together with reductions in fertilizer from the farmers’ tradition practices of 30% N, 27% P2O5, and 12% K2O, resulted in a 600 kg/ha
increase in grain production. Vitazyme contributed to improved nitrogen, phosphorus, and potassium utilization, which resulted in a substantial yield improvement, thus saving the farmer on import costs and improving his total salable crop.
