How to Apply Fertilizer Correctly

Practical field advice for Wheat — knowing how to apply fertilizer matters as much as knowing how much.

What is the correct way to flood DAP for Wheat?
Dissolve the DAP with a DAP solvent in a drum so it fully dissolves. Do NOT open the drum valve at the start of irrigation — wait until the water has covered about 25% of the plot (roughly 1–1.5 kanal in). Then open the valve. Close the drum valve about 10 minutes before you stop the water, so the last flow of water carries the dissolved fertilizer evenly to the far end of the field.
Should urea be flooded with irrigation water, or broadcast afterwards?
Do NOT flood urea. Flooding loses 40–50% of nitrogen through leaching (deep percolation) and denitrification (lost as gas). Instead, broadcast (chhatta) the urea 1–3 days after irrigation, when the soil is moist (tar-wattar condition). This gives 30%+ better absorption than flooding.
How can I distribute fertilizer evenly across the field?
Open the fertilizer drum valve only after irrigation water has already entered 1–1.5 kanal — opening it too early empties the drum before the far end is reached. If the field is not laser-leveled, divide one acre into 2–4 plots (kyare): 2 plots for heavy clay soils, 3–4 for loam, and fertigate each plot separately. Keep checking both the field and the drum during irrigation until you get a feel for the timing.
When should phosphorus and potash be applied?
Phosphorus (P₂O₅) and potash (K₂O) are best applied at sowing as a basal dose, placed in the seedbed. If you missed it at sowing, dissolve the fertilizer (use a DAP solvent for DAP) and flood it at the first or second irrigation — flooding is far more effective than broadcasting for phosphorus and potash at that stage.

Conditions de culture

Sol
Well-drained loam to clay loam; pH 6.0–7.5.
Eau
4–6 irrigations: crown-root initiation (~21 days) is the most critical.
Saison de culture
Sow late October – November; harvest March – April.

Stades de croissance et fertilisation

1

Basal (at sowing) · Day 0

Full phosphorus + potassium + ⅓ nitrogen with seedbed preparation.

2

Crown root initiation · ~21 days

⅓ nitrogen with first irrigation — the most critical top-dressing.

3

Flowering · ~60–70 days

Remaining ⅓ nitrogen before flowering.

Options d'engrais organiques

Le fumier de ferme bien décomposé, le compost ou le lombricompost peuvent être utilisés comme amendement de base du sol pour Wheat : ils construisent la structure du sol et libèrent lentement les nutriments au cours de la saison. Étant donné que la teneur en nutriments organiques varie selon la source, complétez les besoins précis en nutriments avec un engrais minéral calculé pour votre culture et votre région.

Il n'existe aucune dose biologique vérifiée spécifique à la culture pour cette culture ; les conseils ci-dessus constituent une pratique générale et non une recommandation mesurée. Faites tester votre matériel en laboratoire pour une planification précise.
