The application of fertilizers during the second irrigation of wheat is a crucial step in ensuring proper nutrition for the crop to maximize yield. Here's a summary of the practice, incorporating your suggestion:
Application Details:
Timing:
Second irrigation is typically done during the tillering stage (around 30–40 days after sowing). This is a critical phase for nutrient uptake as the plants are actively developing tillers, which directly influence grain yield.
Fertilizer Choice:
Calcium Ammonium Nitrate (CAN):
Apply 50 kg per acre after irrigation. CAN provides a balanced source of nitrogen (around 27%) in both ammonium and nitrate forms, ensuring steady and efficient nitrogen availability to the plant.
Method of Application:
Spreading: Uniformly broadcast CAN over the field after the irrigation water has subsided. This ensures the fertilizer dissolves into the soil without being washed away.
Avoid applying CAN directly to standing water to minimize nitrogen losses.
Supplementary Fertilizers (if needed):
Depending on soil fertility and prior applications:
Phosphorus & Potassium: Usually applied at sowing, but if deficiency symptoms appear, supplementary application via foliar spray can be done.
Micronutrients (e.g., zinc): Apply foliar sprays if deficiencies (like stunted growth or pale leaves) are observed.
Weed Management:
Fertilizer applications often promote weed growth. Conduct timely weed removal to ensure the wheat crop makes optimal use of the nutrients.
Benefits of CAN Application at Second Irrigation:
Provides readily available nitrogen to boost tillering.
Improves plant vigor and ensures uniform growth.
Enhances the efficiency of nutrient uptake during a critical growth stage.
If you have any specific regional conditions (e.g., soil type, climate) or farming practices in mind, adjustments can be made to fine-tune the recommendations!
