However, deficiency of any or combination of these micro nutrients can have a great effect on the yield potential. Proper fertilization and timing is very important. Complete soil analysis is the best way to evaluate and determine the right nutrient and right amount to be supplied.

REINFORCING RIGHT E

This issue reiterates the role of proper nutrient management through the application of the right Element, Amount, and Timing of fertilizers to help rice farmers deal with the increasing prices of inorganic fertilizers.

The best time to apply foliar fertilizer to rice varies depending on its growth stages, as the effectiveness and nutritional needs differ across periods. Below is a detailed explanation of when and how to properly use foliar fertilizer:

1. Seedling Stage (Tillering Phase)

• Purpose: Promote root development and enhance stress resistance.
• Method: Apply foliar fertilizer during the early tillering stage, approximately 20 days after sowing. This timing boosts root growth and improves the plant’s ability to withstand environmental stress.
• Precautions: Avoid application during rainy weather or high-temperature periods to prevent reduced effectiveness.

2. Jointing and Booting Stage

• Purpose: Strengthen stems and improve photosynthetic efficiency.
• Method: Start application around 40 days after sowing, when rice enters the jointing and booting phase. This promotes sturdy stems and enhances photosynthesis, laying the foundation for later heading and flowering.
• Precautions: Avoid rainy or hot conditions.

3. Heading and Flowering Stage

• Purpose: Ensure grain plumpness and increase yield.
• Method: Apply foliar fertilizer beginning at 50 days after sowing, during the heading and flowering period. This supports grain development and boosts productivity.
• Precautions: Avoid application during rain or extreme heat.

4. Pre-Harvest Maturity Stage

• Purpose: Enhance nutrient accumulation and disease/pest resistance.
• Method: Apply foliar fertilizer throughout the growth cycle as needed, with the final application before harvest. This ensures efficient nutrient uptake and prepares the crop for optimal ripening.
• Precautions: Choose sunny, moderate-temperature days for application.

5. Selecting and Using Foliar Fertilizer

• Selection: Use beneficial formulations like potassium dihydrogen phosphate (KH₂PO₄) or urea.
• Application Method: Dilute the fertilizer to the recommended concentration and spray evenly over the leaves using a fog nozzle. Avoid overapplication to prevent fertilizer burn.
• Precautions: Monitor the crop for adverse reactions and consult experts if issues arise.

6. Application Frequency and Intervals

• Frequency: Adjust based on growth conditions, but generally apply once a week.
• Interval: Maintain 7–10 days between applications to allow sufficient nutrient absorption.

proper timing and methods for foliar fertilization are critical to maximizing rice yield and quality. Farmers should follow these guidelines carefully to achieve the best results.
