If your wheat crop has been producing less than you expect, the problem is almost always traceable to one of a handful of manageable factors — seed quality, fertilizer timing, soil condition, or water stress at the wrong moment.
Pakistan's average wheat yield sits at around 2.8–3.0 tonnes per acre, but progressive farmers in Punjab regularly achieve 4.0–4.5 tonnes per acre using the same land and the same inputs — just applied more precisely.
In this guide, you will find the specific agronomic practices that drive yield improvement: what to fix before sowing, what to apply during the growing season, and what mistakes to stop making. No expensive equipment is required for most of these steps.
Choose the Right Wheat Variety for Your Soil and Climate
The single highest-impact decision in wheat production happens before you plant anything. The variety you choose sets the ceiling for everything else.
For rain-fed or canal-irrigated conditions in Punjab, varieties like NARC-2011, Akbar-2019, and Galaxy-2013 have consistently delivered strong yields across smallholder farms. For areas prone to yellow rust, disease-resistant varieties such as Ujala-2016 should be prioritized even if the yield ceiling is slightly lower — a resistant crop that stands is more valuable than a high-yield variety that collapses to disease.
What to Look for When Selecting a Variety
- Yield potential under your irrigation level — A variety bred for high-input, fully irrigated conditions will underperform on a farm with two or three waterings per season. Match the variety to your actual water availability.
- Maturity duration — Early-maturing varieties (95–105 days) suit areas where heat stress arrives early in April. Late-maturing varieties may deliver higher yield in cooler regions but risk heat damage if sown late.
- Disease resistance — Check the Punjab Agriculture Department's current recommended variety list for rust ratings. Yellow rust and stem rust can reduce yield by 30–70% in susceptible varieties if conditions are favorable.
- Seed certification — Always buy certified seed from a registered dealer or government seed corporation. Uncertified seed carries contamination, lower germination rates, and unknown field performance.
Prepare Your Soil Properly Before Sowing
Wheat roots need loose, well-aerated soil to penetrate deeply and access water and nutrients. A poorly prepared seedbed is one of the most common — and most overlooked — reasons for uneven germination and reduced yield.
The ideal seedbed for wheat is firm enough that a footprint compresses only 1–2 cm into the soil. If your foot sinks deeper, the bed is too loose and seed-to-soil contact will be poor. If the soil is cloddy and hard, seeds will not germinate evenly.
Recommended Soil Preparation Steps
- Plough to 20–25 cm depth immediately after the previous crop is harvested. Deep ploughing breaks compaction layers that restrict root growth.
- Apply farmyard manure (FYM) at 8–10 tonnes per acre before the final plough, if available. This improves water retention in sandy soils and drainage in clayey soils.
- Planking — After ploughing, run a plank or rotavator to level the seedbed and break large clods. Two passes are usually needed.
- Check soil moisture before sowing. The soil should be moist enough to hold a shape when squeezed but not wet enough to stick to your hand. Sowing into dry soil delays germination; sowing into waterlogged soil causes seed rot.
Farmers in areas with heavy clay soils — common in central Punjab — should raise the seedbed slightly to improve drainage. Furrow sowing in such soils reduces waterlogging around the seed.
Sow at the Right Time and the Right Depth
Planting date has more impact on wheat yield than almost any other input. Wheat sown in the optimal window outperforms late-sown wheat by 15–30%, even with identical varieties and fertilizer rates.
Optimal sowing window for irrigated wheat in Punjab: November 1–20.
For rain-fed wheat in northern areas: October 20 – November 10.
Sowing after November 25 in the irrigated plains consistently reduces yield. Each week of delay after that point can cost 100–150 kg per acre as the crop increasingly competes with rising spring temperatures during grain fill.
Sowing Depth and Seed Rate
- Sowing depth: 4–6 cm. Shallower than 3 cm and seeds dry out before germination; deeper than 7 cm and the seedling struggles to emerge.
- Seed rate (broadcast): 50–60 kg per acre.
- Seed rate (drill): 40–50 kg per acre. Drill sowing is more efficient and allows better placement of seed and fertilizer.
Seed treatment before sowing reduces early fungal infection significantly. Treat seed with Thiram or Raxil at the recommended label rate and allow to dry in shade before drilling.
Apply Fertilizer at the Right Time — Not Just the Right Amount
Wheat is a heavy feeder, but the timing of fertilizer application is as important as the quantity. Fertilizer applied at the wrong growth stage either cannot be used by the plant or is lost to the environment.
A standard fertilizer program for irrigated wheat in Punjab:
| Nutrient | Total Rate (per acre) | When to Apply |
|---|---|---|
| Nitrogen (N) | 60–70 kg | Split: half at sowing, half at first irrigation (tillering) |
| Phosphorus (P₂O₅) | 35–40 kg | Full dose at sowing — mix into seedbed |
| Potassium (K₂O) | 25–30 kg | Full dose at sowing (if soil test indicates deficiency) |
Urea Application — Critical Rules
Urea is the most widely used nitrogen source, and it is also the most commonly misapplied. Two practical rules prevent most urea losses:
Do not apply urea on dry soil. Urea exposed to dry, hot soil volatilizes rapidly — nitrogen escapes as ammonia gas before the plant can use it. Always apply urea when irrigation is due within 24–48 hours, or immediately after light rainfall.
Apply the second dose at tillering, not later. Nitrogen applied after the jointing stage (when the first node is visible) has minimal effect on grain number and yield. The tillering stage — roughly 25–30 days after germination — is when nitrogen drives tiller production and, therefore, the number of grain heads.
Irrigate at the Right Growth Stages
Wheat requires approximately 400–500 mm of water over its growing season in the irrigated plains of Punjab. But it is not the total amount that determines yield — it is whether water is available at the five critical stages when the crop cannot tolerate stress.
| Growth Stage | Days After Sowing | Irrigation Priority |
|---|---|---|
| Crown root initiation | 21–25 | Critical — never skip |
| Tillering | 40–45 | High |
| Jointing | 65–70 | High |
| Booting | 85–90 | Critical — never skip |
| Grain fill (milky stage) | 105–115 | High |
If you can only give your crop three irrigations, prioritize crown root initiation, booting, and grain fill. Skipping irrigation during booting is one of the most common causes of shriveled, lightweight grain.
For farms with canal water shortages, alternate furrow irrigation — applying water to every other furrow — can reduce water use by 30–40% while maintaining 85–90% of yield in most soil types. For more water-saving techniques, see our guide on Irrigation & Water Management.
Scout for Disease and Pest Pressure Early
Yellow rust is the biggest yield threat to wheat in Pakistan. It spreads rapidly in cool, moist weather and can destroy a field within two weeks if it is not caught early. Scouting once a week from December through February is the minimum — in wet winters, scout twice a week.
Signs of yellow rust: Bright yellow-orange pustules arranged in stripes along the leaf blade. Affected leaves look like they have been dusted with yellow powder.
If yellow rust is detected on more than 5% of plants in a field, apply a fungicide immediately. Propiconazole (Tilt 250 EC) at 250 ml per acre in 100 litres of water gives reliable control when applied at the first sign of infection.

Common Pest Problems and What to Do
- Aphids: Monitor from tillering onwards. Populations above 5–10 aphids per tiller can reduce yield. Imidacloprid or Dimethoate at label rates give fast knockdown.
- Termites: Especially problematic in sandy soils. Symptoms are wilting tillers that pull out easily from the base. Soil application of Chlorpyrifos at the time of ploughing gives season-long protection in high-risk fields.
- Wheat stem sawfly: Less common but found in some northern Punjab areas. Crop rotation is the most practical management tool — avoid continuous wheat on the same plot.
Common Mistakes That Reduce Wheat Yield
These are the mistakes that consistently appear on farms producing below 3 tonnes per acre. Most are fixable before the next season.
- Sowing too late. This single factor is responsible for more lost wheat yield across Punjab than any other practice. If you sow after November 25, accept that your maximum yield is already reduced. Plan your crop calendar backward from the optimal sowing window.
- Applying all nitrogen at sowing. Full nitrogen applied before emergence is largely wasted — the seedling cannot use it, and rainfall or irrigation leaches much of it before the crop reaches tillering. Always split nitrogen applications.
- Skipping the booting irrigation. Many farmers cut the booting irrigation to save water during shortages. This is a false saving. Water stress during booting directly reduces the number of grains per head — the loss in yield always exceeds the water saved.
- Using saved seed without testing germination. Saved seed loses viability in poor storage conditions. A simple germination test — place 50 seeds on a wet cloth for 7 days and count those that sprout — tells you the germination rate before you commit 50 kg per acre to a field. If fewer than 40 of the 50 sprout, buy certified seed.
- Ignoring soil pH. Wheat performs best at a soil pH of 6.5–7.5. Soils outside this range lock up nutrients even when fertilizer is applied at the correct rate. A basic soil test from the Soil Fertility Institute costs very little and eliminates years of guessing.
