Viet Nga Specialized Rice Fertilizer Set: NPK 25-25-5+TE and NPK VNG 19-9-19+TE

The specialized rice fertilizer set NPK 25-25-5+TE and NPK VNG 19-9-19+TE was developed by Viet Nga Fertilizer to meet the nutritional needs of the rice plant at each growth stage. NPK 25-25-5+TE supports tillering, clump spreading and vigorous early growth, while NPK VNG 19-9-19+TE continues to supply nutrients during panicle initiation and grain filling, helping plants grow in a balanced way, increasing the rate of filled grains and improving rice yield and quality at harvest.

Why Use a Specialized Rice Fertilizer Set?

Throughout the growing season, the rice plant's nutritional needs change markedly from stage to stage. In the early stage, the plant needs suitable nutrients to develop roots, stems and leaves, promote tillering and form productive tillers. As it moves into the reproductive stage, its nutritional needs shift to support panicle formation and the translocation and accumulation of nutrients into the grain. Using a single fertilizer formula for the whole season may therefore not properly meet the plant's needs at each point in time.

Viet Nga's specialized rice fertilizer set is built with formulas suited to each development stage. NPK 25-25-5+TE, high in nitrogen and phosphate, is used during tillering and clump spreading to help the plant develop roots, stems and leaves and increase tillering. When the plant enters panicle initiation and grain filling, NPK VNG 19-9-19+TE, with a balanced nitrogen-to-potash ratio, continues to supply nutrients, supporting panicle formation and nutrient accumulation in the grain.

Using the product set at the right stages lets farmers plan their fertilizing more proactively, reduces the need to blend multiple straight fertilizers themselves, and supplies nutrients that match the rice plant's growth needs. As a result, the crop can develop evenly from the start of the season through grain filling, laying the foundation for higher rice yield and quality at harvest.

Specialized Rice Fertilizer Set NPK 25-25-5+TE and NPK VNG 19-9-19+TE

Viet Nga's specialized rice fertilizer set combines two nutrient formulas used at different stages of the rice plant. NPK 25-25-5+TE focuses on the tillering and clump-spreading period, while NPK VNG 19-9-19+TE is used during panicle initiation and grain filling. This combination supplies nutrients that match the plant's changing needs, from developing roots, stems, leaves and productive tillers early in the season to panicle formation and nutrient accumulation in the grain later on.

NPK 25-25-5+TE – Tillering and Clump Spreading

NPK 25-25-5+TE contains 25% nitrogen (N), 25% available phosphate (P₂O₅), 5% available potash (K₂O), plus secondary nutrients and micronutrients, matching the rice plant's nutritional needs in the early growth stage. The high nitrogen and phosphate content helps the plant develop its roots, promotes stem and leaf growth, encourages strong tillering and increases the number of productive tillers. Supplying the right nutrients during this period helps the paddy develop evenly, creating a sound basis for panicle formation and later yield.

NPK VNG 19-9-19+TE – Panicle Initiation and Grain Filling

When the rice plant moves into panicle initiation and grain filling, NPK VNG 19-9-19+TE, containing 19% nitrogen (N), 9% available phosphate (P₂O₅), 19% available potash (K₂O), plus secondary nutrients and micronutrients, continues to supply the nutrients the plant needs. The balanced nitrogen-to-potash ratio both helps sustain growth and photosynthesis and promotes the translocation and accumulation of nutrients into the grain, contributing to good panicle formation, a higher rate of filled grains, and better rice yield and quality at harvest.

How to Use the Specialized Rice Fertilizer Set NPK 25-25-5+TE and NPK VNG 19-9-19+TE

For the specialized rice fertilizer set to work effectively, farmers should use each formula according to the plant's nutritional needs at each growth stage. NPK 25-25-5+TE is used in the first two applications, from early growth through tillering and clump spreading, supplying nutrients for the development of roots, stems and leaves and the formation of productive tillers. When the plant moves into panicle initiation and grain filling, NPK VNG 19-9-19+TE is used to keep supplying nutrients, supporting panicle formation, sustaining growth and accumulating nutrients in the grain.

Key Notes When Using the Specialized Rice Fertilizer Set

For the NPK 25-25-5+TE and NPK VNG 19-9-19+TE set to perform well in the field, besides applying the right product at each stage, farmers should monitor the growth of the paddy and adjust fertilizer rates to actual conditions. The recommended rates are for reference and may vary depending on rice variety, soil fertility, season and farming conditions in each area.

Fertilize at the Right Time for Each Growth Stage

NPK 25-25-5+TE is used in the early stage through tillering and clump spreading, while NPK VNG 19-9-19+TE suits panicle initiation and grain filling. Using the right formula for each period ensures the plant receives nutrients that match its growth needs and allows each product in the set to play its role.

Monitor the Growth of the Paddy

During cultivation, farmers should visit their fields regularly and observe leaf color, tillering, root development and overall plant growth before each application. In fields with varying fertility or where plants grow unevenly, fertilizer rates should be adjusted accordingly rather than applying one fixed rate to all conditions.

Manage Water Properly When Fertilizing

Water conditions in the field affect how well fertilizer dissolves, how nutrients are absorbed and how efficiently fertilizer is used. Farmers should therefore keep water levels appropriate to each growth stage and avoid fertilizing when the field is at risk of deep flooding or before heavy rain, to reduce nutrient loss.

Combine with Crop Care and Pest Management

Fertilizing should go hand in hand with regular field visits, water management and pest and disease monitoring throughout the rice season. Integrated care helps the plant stay healthy, allows the nutrients from the fertilizer set to be used efficiently, and contributes to good rice yield and quality at harvest.
