Wheat Irrigation & Fertilizer Schedule for Higher Yield
A stage-by-stage wheat irrigation and fertilizer schedule for Gujarat and India — the critical CRI, tillering, flowering and grain-filling stages, plus a balanced NPK plan.
Updated Fri May 22
Water and nutrition decide whether your wheat reaches its yield potential. The good news: wheat responds predictably to a few well-timed irrigations and a balanced fertiliser dose. This guide gives you the stage-by-stage schedule.
The critical irrigation stages
Wheat does not need constant water — it needs water at the right growth stages. Fully irrigated wheat typically takes 4–6 irrigations:
| Stage | Timing (days after sowing) | Why it matters |
|---|---|---|
| Crown root initiation (CRI) | 20–25 DAS | Most critical — sets root system and tiller number |
| Tillering | 40–45 DAS | Builds productive tiller count |
| Jointing | 60–65 DAS | Stem elongation and spike development |
| Flowering | 80–85 DAS | Pollination and grain set |
| Grain filling | 100–105 DAS | Grain weight and test weight |
If you remember nothing else, remember CRI at 20–25 days. It has the largest single effect on yield of any irrigation. Never let the crop go short of water at this stage.
Managing with limited water
Not every farmer has water for 5–6 irrigations. If yours is limited, the smartest move is to match the variety to the water, then prioritise the most valuable irrigations:
- With 1–2 irrigations, grow a drought-tolerant, early variety such as LOK-1 and place your irrigations at CRI and grain filling.
- With full irrigation, a high-yield variety such as GW-496 can express its full 50–60 q/ha potential.
This is covered further in the variety comparison.
A balanced fertilizer plan
Always base your dose on a soil test — the figures below are a general guide, not a substitute for one.
- At sowing (basal): the full phosphorus and potash dose, plus roughly half the nitrogen.
- At CRI / tillering irrigation: top-dress the remaining nitrogen.
The key discipline is balance. Over-applying nitrogen produces a lush, dark canopy that lodges (falls over) and is far more prone to rust — costing you the very yield you were chasing. Phosphorus supports root and tiller development early; potash improves grain filling and stress tolerance.
Putting it together
A reliable irrigated-wheat plan looks like this:
- Basal P + K + half N at sowing.
- First irrigation at CRI (20–25 DAS) + top-dress remaining N.
- Irrigate at tillering, jointing, flowering and grain filling as water allows.
- Keep nitrogen balanced to avoid lodging and rust.
Pair this with timely sowing (see sowing time and seed rate) and the right variety, and you have the three pillars of a high-yield wheat crop. Return to the complete wheat farming guide for the full picture.
Frequently Asked Questions
Which is the most critical irrigation stage for wheat?+
Crown root initiation (CRI), about 20–25 days after sowing, is the single most critical irrigation. Missing it causes the largest yield loss of any stage.
How many irrigations does a wheat crop need?+
Fully irrigated wheat needs about 4–6 irrigations: CRI (20–25 DAS), tillering (40–45 DAS), jointing (60–65 DAS), flowering (80–85 DAS) and grain filling. Limited-water crops are managed with 1–3 well-timed irrigations.
What fertilizer does wheat need?+
Apply a balanced NPK dose based on a soil test. As a general guide, give a basal dose of phosphorus and potash with part of the nitrogen at sowing, and top-dress the remaining nitrogen at the CRI/tillering irrigation. Avoid excess nitrogen, which encourages rust and lodging.
