  • Supermarkets
  • Hotels and restaurants
  • Online vegetable platforms
  • Export markets
  • Urban consumers

Why Demand is Increasing in India

  • Growing health awareness
  • Demand for salad vegetables
  • Expansion of organized retail chains
  • Year-round consumption in cities

2. Advantages of Growing Cucumber Under Shadenet

Benefit Explanation
Protection from harsh weather Reduces damage from heavy rain, wind, and heat
Better yield 2–3 times higher than open field
Quality fruits Uniform size and color
Reduced pest incidence Controlled environment
Efficient water use Drip irrigation system
Higher market price Premium produce quality

 

Productivity Comparison

System Yield (kg/sq.m)
Open Field 3–5
Shadenet 8–12

3. Climate and Soil Requirements

Climate

  • Ideal temperature: 22°C – 30°C
  • Minimum: 18°C
  • Maximum: 35°C (above this affects fruit quality)
  • Relative Humidity: 60–80%

Coastal climates benefit greatly from shadenet protection against excess heat and rainfall.

Soil

  • Well-drained sandy loam or loamy soil
  • pH: 6.0 – 7.5
  • Rich in organic matter
  • Avoid waterlogging areas

4. Shadenet Structure Requirements

Parameter Recommendation
Structure size 1000 sq.m (example unit)
Shade percentage 35%–50% green shadenet
Height 3.5–4 meters center height
Orientation North–South direction
Ventilation Side openings with insect net
Frame material GI pipes (rust-resistant)

 

5. Land Preparation and Bed Formation

Steps

  1. Deep ploughing (1–2 times)
  2. Remove weeds and residues
  3. Incorporate organic manure

Basal Application

  • FYM/Compost: 3–4 tons per 1000 sq.m
  • Neem cake: 100 kg
  • Trichoderma enriched compost recommended

Bed Formation

Bed Width Height Pathway
1 meter 30–40 cm 40–50 cm

 

Install drip lines before mulching.

6. Suitable Hybrid Varieties for Protected Cultivation (India)

Parthenocarpic hybrids (fruit without pollination) are preferred.

Hybrid Features
Kafka Uniform fruits, high yield
Terminator Heat tolerant
Multistar Excellent fruit quality
KPCH-1 Popular protected hybrid
Hilton Export quality fruits

7. Nursery Raising and Transplanting Method

Nursery Raising

  • Use protrays (98 cells)
  • Media: Cocopeat + Vermicompost + Bioagents
  • Seed rate: 250–300 g per 1000 sq.m

Steps

  1. Sow one seed per cell
  2. Maintain light irrigation
  3. Seedlings ready in 12–15 days

Transplanting

  • Transplant at 2–3 true leaf stage
  • Prefer evening planting

8. Spacing and Planting Layout

Row Spacing Plant Spacing Plants/1000 sq.m
1.2 m 45 cm 1800–2000 plants

Use silver-black mulch to reduce weeds and conserve moisture.

9. Drip Irrigation and Fertigation Schedule

Irrigation

  • Daily light irrigation
  • Avoid excess moisture

Stage-wise Fertigation Schedule (per 1000 sq.m)

Crop Stage Days Nutrient Recommendation
Establishment 0–10 19:19:19 – 1 kg/week
Vegetative 11–25 Calcium nitrate + Urea
Flowering 26–40 13:0:45 + Micronutrients
Fruiting 41–70 0:0:50 + Calcium nitrate
Harvest stage 70+ Balanced NPK + MgSO₄

Tip: Apply nutrients in split doses through drip for better uptake.

10. Training and Pruning Methods (Trellising System)

Training improves light penetration and fruit quality.

Method

  • Install GI wire at 6–7 ft height
  • Tie plastic twine to each plant
  • Train plant vertically

Pruning Rules

  • Remove side shoots up to 5th node
  • Maintain single stem
  • Remove old leaves regularly

11. Pollination Management (Parthenocarpic Varieties)

English cucumbers grown under shadenet are mostly parthenocarpic.

Meaning:
Fruits develop without pollination or seeds.

Advantages

  • No need for bees
  • Uniform fruit shape
  • Higher productivity

Avoid insect entry to prevent unwanted pollination.

12. Pest and Disease Management (IPM Practices)

Common Pests

Pest Management
Whiteflies Yellow sticky traps
Thrips Blue sticky traps
Aphids Neem oil spray
Mites Maintain humidity

Diseases

Disease Control
Powdery mildew Sulfur spray
Downy mildew Prevent excess humidity
Root rot Trichoderma application

 

IPM Tips

  • Maintain sanitation
  • Remove infected plants
  • Use biological control agents

13. Temperature and Humidity Management

Parameter Ideal Level
Temperature 22–30°C
Humidity 60–80%

Management Practices

  • Open side vents during hot afternoons
  • Use fogging/light irrigation in summer
  • Ensure airflow during monsoon

14. Harvesting Stage and Yield Expectations

Harvesting

  • First harvest: 35–40 days after transplanting
  • Harvest interval: Every 2–3 days
  • Fruit length: 18–22 cm

Expected Yield

Area Yield
1000 sq.m 8–12 tons

15. Post-Harvest Handling and Grading

Grading Standards

Grade Length Quality
Premium 20–22 cm Straight, dark green
A Grade 18–20 cm Minor variation
B Grade Irregular Local market

Handling Tips

  • Harvest early morning
  • Avoid sun exposure
  • Pack in ventilated crates

16. Marketing Opportunities and Buyer Channels

Farmers can sell through:

  • Supermarkets
  • Vegetable aggregators
  • Online grocery platforms
  • Hotels & restaurants
  • Local wholesale markets
  • Contract farming buyers

Tip: Direct marketing gives 20–30% higher price.

17. Common Mistakes Farmers Should Avoid

❌ Choosing open-field varieties
❌ Over-irrigation causing root diseases
❌ Poor ventilation management
❌ Not pruning plants
❌ Excess nitrogen fertilizer
❌ Delayed harvesting

18. Conclusion: Practical Tips for Beginners

English cucumber under shadenet is one of the most profitable protected cultivation crops suitable for Andhra Pradesh and Telangana farmers.

Beginner Success Tips

  • Use parthenocarpic hybrids only
  • Follow strict fertigation schedule
  • Maintain hygiene inside shadenet
