Precision Farming Techniques in Vegetable Crops

a. Protected Cultivation

  • Use of greenhouses, shade nets, plastic tunnels, and hydroponics for crops such as tomato, cucumber, capsicum, lettuce, and leafy greens.
  • Provides controlled environment for temperature, humidity, and light.
  • Enhances off-season and export-oriented production.

 

b. Precision Irrigation and Fertigation

  • Drip irrigation combined with fertigation units for site-specific nutrient delivery.
  • Soil moisture sensors used for real-time irrigation scheduling.
  • Reduces water use by 40–60% and fertilizer use by 20–30%.

 

c. Soil and Crop Monitoring

  • GIS and GPS mapping to identify variability in soil fertility.
  • Use of chlorophyll meters, SPAD meters, and leaf color charts to monitor crop nutrition.
  • Disease and pest hotspots identified using drones and imaging systems.

 

d. Hydroponics and Soilless Cultivation

  • Crops like tomato, lettuce, spinach, strawberry grown in nutrient solutions or substrates (cocopeat, perlite).
  • Allows production in areas with poor soils and limited water.

 

e. Mechanization and Automation

  • Use of transplanters, sensor-based sprayers, robotic weeders, and harvesting aids in vegetable production.
  • Precision seeders ensure uniform spacing and depth.

 

f. Integrated Pest and Disease Management (IPDM)

  • Use of yellow sticky traps, pheromone traps, biocontrol agents and drone-based pesticide application.
  • Minimizes chemical use and maintains produce quality.
