Fertilizing For The Rice Panicle Stage With NPK Con CO USP 20-10-0+10,5Ca+7S

During the panicle formation stage, rice plants need to accumulate a significant amount of nutrients to nourish the panicle, so the nutrient requirements are very high at this time. So, how can we determine the appropriate time to apply panicle fertilizer? What is the correct method for fertilizing at the panicle stage? Let’s explore these details with Baconco in the following article.

What is Panicle Fertilization?

Rice panicle formation refers to the stage before the rice plant enters the panicle development period. This is the phase where the rice plant begins to differentiate and form reproductive organs.

During this period, the rice plant undergoes noticeable changes in morphology, leaf color, physiology, and its ability to withstand environmental conditions. With the naked eye, farmers can identify the panicle when it reaches a size of about 1mm (also known as “cockroach droppings”). After the panicle forms, it continues to grow, elongate, and create structures such as the ear, branches, and flowers. 

At this point, the length of the panicle can reach 6–12 cm, equivalent to half the length of the fully mature ear. As the process continues, the panicle grows larger, swells, and elongates further.

The panicle formation phase ends when the rice panicle matures and is ready to flower. This period directly impacts the rice yield, so farmers need to pay attention to proper care and fertilization to ensure the best results.

The importance of panicle fertilization

The panicle formation stage is when the rice plant transitions from the vegetative phase to the reproductive phase. At this time, the plant requires a large amount of nutrients to:

• Develop vigorously and flower evenly: Ensure a high and uniform flowering rate across the field.
• Increase photosynthesis: Larger, thicker, and upright panicle leaves help absorb more light, supporting rice grain formation quickly and with higher quality.
• Limit pests and lodging: A healthier, stronger plant reduces the risk of pest attacks and lodging during rainy or windy weather.
• Produce firm grains, high yield: Provide enough nutrients for the rice to form large, firm grains, ensuring superior yield.

NPK CON CO USP 20-10-0+10,5Ca+7S: An Effective Fertilizer Solution for the Panicle Formation Stage

When entering the panicle formation phase, the rice plant needs a large amount of nutrients to grow vigorously, flower evenly, and achieve high yield. One of the top choices for farmers is NPK CON CO USP 20-10-0+10.5Ca+7S – a special fertilizer with an outstanding nutrient formula, providing comprehensive support for rice plants.

Nutrient Components:

• Nitrogen (N) 20%: Provides essential nutrition, promotes growth and development, helping the plant become stronger with larger, thicker panicle leaves.
• Phosphorus (P2O5) 10%: Supports root system development, helping the plant absorb nutrients efficiently and stimulates panicle differentiation.
• Calcium (Ca) 10.5%: Neutralizes acidity, reduces soil salinity, creating favorable conditions for healthy rice plant growth and increasing resistance to pests.
• Sulfur (S) 7%: Improves photosynthesis, supports protein synthesis, enhances resistance to adverse conditions, and boosts the nutritional value of rice grains.

Outstanding Advantages:

When combined with Potassium (61%), NPK CON CO USP 20-10-0+10.5Ca+7S is an optimal solution for the panicle formation stage. The product not only helps the plant flower successfully but also:

• Makes the rice plant stronger and reduces lodging.
• Increases disease resistance, particularly against diseases like leaf blast, neck blast, and panicle blast.
• Improves the quality and nutritional value of the rice grain.

Usage Instructions:

For optimal yield, farmers should use the product with the following dosage (for 1 hectare):

• NPK CON CO USP 20-10-0+10.5Ca+7S: 100–120kg
• Potassium (61%): 50–60kg

Note: The usage rate may be adjusted based on soil type, rice variety, and the plant's growth status.
