Best Fertilizer for Cotton in Punjab
Cotton fertilizer schedule for Punjab kharif season — Sona DAP at sowing, split Sona Urea across flowering and boll-set, plus Zinc and Boron foliar for fruit retention.
Cotton is the backbone of Pakistan’s textile economy and one of the most fertilizer-responsive crops a kissan can grow. But cotton is also unforgiving — wrong NPK ratios, wrong split timing, or missed micronutrients show up as small bolls, dropped fruit, or lint with low staple length. This is the standard South Punjab cotton fertilizer schedule we recommend to BT-Bollgard and conventional cotton growers walking into our Multan branch.
Quick schedule — per acre, irrigated Punjab cotton
| Stage | Time | Fertilizer | Rate |
|---|---|---|---|
| Land prep | Mar–Apr | Sona DAP | 1.5 bags (75 kg) |
| Land prep | Mar–Apr | Sona Zinc | 5 kg |
| Sowing | Apr–May | Cotton seed | per variety |
| First irrigation | ~25 days after sowing | Sona Urea Prilled | 0.5 bag (25 kg) |
| Squaring (flowering bud) | ~45–55 days | Sona Urea Prilled | 1 bag (50 kg) |
| First boll-set | ~75 days | Sona Urea Prilled | 1 bag (50 kg) |
| Squaring + boll-set | as needed | Boron + Zinc foliar | 2% spray |
Total inputs per acre: 1.5 bags DAP + 2.5 bags Urea + Zinc + Boron foliar.
Why cotton needs DAP-heavy starter
Cotton has the deepest tap-root of any major Pakistani crop — up to 1.5 metres in good soil. That root architecture is built in the first 30 days from phosphate availability, and a phosphate-starved cotton plant will under-produce regardless of how much nitrogen you push later. DAP at sowing is non-negotiable.
The 1.5-bag-per-acre DAP rate is higher than wheat (1 bag) because cotton’s longer cycle (140–180 days) and deeper root structure demand more phosphate reserve. Broadcast and disc into the seedbed during land prep, or band along the planned planting line.
Why Urea is split across three doses
Cotton has three distinct phenology stages, each with its own nitrogen demand:
- Vegetative (sowing to first squaring, ~50 days): light nitrogen — too much pushes vegetative growth at the cost of fruiting structures
- Squaring to first boll-set (~50–80 days): heavy nitrogen — the plant is building flower buds and the early bolls
- Boll development (~80–140 days): moderate nitrogen — supports fibre development without re-vegetating the plant
A single front-loaded Urea application produces a tall, leafy, low-yielding cotton plant. Three splits aligned to these stages produce a compact, productive plant with high boll-count. The squaring application (~50 days) is the most important — get this right and you secure the season’s boll count.
Boron + Zinc foliar — the difference between average and good cotton
Cotton is hyper-sensitive to boron deficiency at flowering. The symptom is dropped squares and bolls — the kissan blames the variety, the heat, or the pesticide, but the cause is often boron limitation. A 2% boron foliar spray at squaring and again at first boll-set holds fruit retention significantly higher.
Zinc plays a similar role on chlorophyll and pollen viability. South Punjab soils — particularly those in cotton-wheat rotation — often run zinc-deficient by the cotton season. Foliar zinc at the same timings is cheap insurance.

BT-Bollgard vs conventional cotton
The fertilizer schedule above applies equally to BT-Bollgard II and conventional cotton varieties. BT cotton’s pesticide cost is lower (the Bt-gene handles bollworm), but the nutrient demand is the same — sometimes slightly higher because higher boll retention means more fruit to feed.
What not to do
- Don’t apply DAP after sowing — phosphate at top-dress is wasted in cotton just as it is in wheat
- Don’t front-load Urea — a single 2.5-bag application at first irrigation produces tall vegetative cotton with low boll-count
- Don’t skip the boron foliar at squaring — fruit retention will fall and you’ll never know why
- Don’t use unbranded mandi DAP — counterfeit fertilizer is rampant in South Punjab cotton districts. Anti-counterfeit seal or don’t buy.
- Don’t over-water at first boll-set — cotton dislikes wet feet during boll development; excess water + excess nitrogen causes boll shed
