Cotton cultivation is a combination of timing, technology, and tradition. Every stage, from selecting the best seed to overseeing post-harvest procedures, has an impact on productivity and fiber quality. A streamlined, evidence-based method guarantees production, pest resilience, and market readiness regardless of your level of experience as a grower.
This blueprint examines every phase of cotton agriculture, emphasizing soil preparation, seed selection, nutrient cycles, water regulation, pest control, and harvesting techniques. If the proper choices are made at every stage, cotton has the potential to be a high-value crop for both small and large farms.
How Do You Prepare the Soil for Cotton Farming?
Deep, well-drained loamy soils with a pH of 6.5 to 8.0, which is neutral to slightly alkaline, are ideal for cotton growth. The first preparation is crucial since poor soil management can diminish yield by as much as 25%.
Key steps include:
- Deep ploughing (25-30 cm) in the off-season to break hardpan layers
- Soil testing to identify pH, micronutrient levels, and organic matter
- Application of farmyard manure (FYM) or compost at least 30 days before sowing
A fine seedbed supports better root development. Fields with good tilth reduce germination failure caused by clod-forming or waterlogging.
Which Cotton Seed Varieties Perform Best?
Selecting the right seed hybrid determines resistance to pests, lint output, and maturity period. Farmers now prefer biotech hybrids with insect tolerance and high boll count.
Among the most preferred options in recent years is Goldi-333 BGll Hybrid Cotton Seeds, chosen for its consistent yields, early maturity, and ability to withstand sucking pests under dry conditions. These traits offer risk mitigation for farmers in both irrigated and rainfed zones.
Modern seeds include:
- BG-II hybrids for resistance against American bollworm and pink bollworm
- Non-GMO varieties preferred for organic production in niche markets.
The climate, soil type, and sowing window of the zone must all be considered while choosing seeds. For instance, Telangana encourages medium-duration, boll-heavy hybrids, whereas Gujarat prefers early-maturing, drought-resistant varieties.
What’s the Ideal Time and Method to Sow Cotton?
Monsoon patterns determine when cotton should be sown. While the northern belts start planting in April or May, central and southern India start sowing in June to mid-July. Plants exposed to higher pest pressure and less boll setting are the results of delayed sowing.
Sowing methods include:
- Drill sowing with a row spacing of 90-120 cm and plant spacing of 45-60 cm
- Transplanting (less common) in seed-scarce areas or for staggered harvest
Optimal germination needs soil temperatures between 20°C and 30°C. Seed priming using bio-fungicides or Trichoderma viride increases germination by 7-10% on average.
How to Structure a Cotton Fertilization Schedule?
A well-planned nutrient regimen enhances plant recovery, fiber strength, and boll count during stress. Cotton requires many minerals, particularly micronutrients like boron, zinc, nitrogen, and potassium.
Recommended dose per hectare (general):
- Nitrogen: 150-180 kg
- Phosphorus: 60-80 kg
- Potassium: 60-100 kg
Split nitrogen into three applications: at sowing, 45 days after sowing (DAS), and 75 DAS. Foliar sprays with micronutrients can address deficiencies faster and help during flowering and boll formation phases.
According to an ICAR - Central Institute for Cotton Research report, balanced fertilization can boost lint yield by 18% and reduce pest incidence in potassium-rich fields.
How to Optimize Irrigation in Cotton Fields?
Cotton is moderately drought-tolerant but needs steady moisture at critical stages—flowering, boll development, and early boll opening.
Efficient irrigation methods include:
- Drip irrigation, which saves 30-40% water and improves fertigation
- Alternate furrow irrigation, suitable for large flat fields
Critical moisture stress between 60-90 DAS leads to boll shedding. In black soils, avoid over-irrigation, which promotes root rot and fungal issues.
Irrigation scheduling tips:
- First irrigation: 30-40 DAS
- Subsequent irrigation: every 12-15 days during peak flowering
- Stop irrigation two weeks before final picking to avoid wet bolls
How to Protect Cotton From Insect Pests?
If pests are not managed quickly, they result in large losses. The top three threats are jassids, whiteflies, and pink bollworms. Without effective IPM techniques, bollworm infestations alone can cause a 30% reduction in yield.
Integrated Pest Management (IPM) involves:
- Use of pheromone traps and sticky traps for early detection
- Neem oil sprays and biological agents like Bacillus thuringiensis
- Rotating pesticides to prevent resistance development
Bt cotton hybrids like BG II varieties offer genetic protection against specific larvae but still need field scouting. Intercropping with maize or marigold also reduces pest density by disrupting their host preference cycle.
"Prevention starts in the seedbed, but persistence wins in the field. Stay ahead of pests, not beside them."
How to Manage Weed Competition?
Weeds compete for water, nutrients, and sunlight, especially during the first 60 days. Manual weeding is common but labor-intensive.
Modern approaches include:
- Pre-emergent herbicides like pendimethalin within 2 days of sowing
- Post-emergent options such as quizalofop-p-ethyl or glyphosate in tolerant varieties
- Mulching in small-scale farms using cotton husks or straw
Weed-free fields during early growth result in better branching and higher boll setting. Delayed weeding reduces plant vigor and boll size.
What Are the Critical Growth Stages of Cotton?
Understanding growth stages helps align interventions effectively. Cotton growth spans 120 to 180 days depending on the hybrid.
Key stages include:
- Emergence (0–15 days): Germination and early seedling growth
- Vegetative (15–45 days): Branching and canopy development
- Flowering (45–75 days): Begins squaring and early blooms
- Boll Formation (75–120 days): Peak nutrient and water demand
- Maturity and Boll Opening (120+ days): Ready for first picking
Stress at flowering or early boll formation causes irrecoverable yield loss. Monitor closely during this window for nutrient uptake, pest presence, and growth uniformity.
How to Plan Harvest and Post-Harvest Activities?
Cotton picking must align with boll maturity to maintain fiber quality. Harvest too early and you lose weight; harvest too late, and lint turns yellow due to exposure.
Picking strategies:
- Multiple hand pickings every 10-15 days to reduce trash content
- Avoid picking early morning to prevent moisture-stained lint
- Store in ventilated, dry spaces to prevent fungal damage
Lint needs to be washed, dried, and wrapped in breathable material after being collected. Some farmers now separate lint and seed on-farm to increase profitability using micro ginning devices.
Cotton that has more than 12% moisture content should not be stored. Prior to storage, determine the level of dryness using hygrometers or field sensors.
