Optimal Timing for NPK Fertilizer Application in Wheat Cultivation

Dr. Amit Bhatnagar, Professor at Pantnagar Agricultural University, explains the best timing for applying NPK fertilizers in wheat cultivation to maximize nutrient absorption and crop yield.

Fertilizers Discussed

Nitrogen: Urea
Phosphorus: DAP, SSP, TSP
Potassium: MOP, SOP

Phosphorus (P) and Potassium (K) Application

Apply 100% of phosphorus and potassium fertilizers at the time of sowing (basal dose).
Do not apply P and K fertilizers to standing crops after sowing or via spraying/broadcasting because these nutrients tend to get fixed in the soil and do not move easily to the roots.
For effective absorption, phosphorus and potassium must be placed near the seed/root zone.

Nitrogen (N) Application

Nitrogen should be applied in three equal splits:

At sowing (basal dose): 1/3 of total nitrogen
20-25 days after sowing: 1/3 at the CRI (Crown Root Initiation) stage, coinciding with the first irrigation
40-45 days after sowing: 1/3 during maximum tillering, usually with the second irrigation

Additional notes:

Nitrogen should always be applied with irrigation to ensure adequate moisture for absorption.
Some light soils may require a third irrigation for optimal nitrogen uptake.

Important Advice

Avoid applying phosphorus and potassium fertilizers to standing crops as their effectiveness is very low. Proper timing of fertilizer application ensures full utilization of costly fertilizers and leads to better crop production.
