Tomato (Lycopersicon esculentum)

  • Family: Solanaceae
  • Origin: Peru (South America)
  • Chromosome Number: 2n = 24
  • Fruit Type: Berry
  • Nicknames: Protective Food. Third most important vegetable (after Potato & Onion)
  • Climatic Nature: Summer season crop; sensitive to frost

 

Area, Production & Export

  • Global Position: No.1 processing vegetable in the world
  • India:3rd in area & production among vegetables
  • Export Centers: Nasik, Pune (MH), Bengaluru (KA)
  • Tomato Products in Export: Puree, Paste

 

Soil & Climate Requirements

  • Soil: Well-drained loamy, rich in organic matter (pH: 6.5–7.5)
  • Optimal Lycopene Formation: 21–24°C
  • Lycopene production drops: Above 27°C
  • Crop Duration: 110–115 days (from transplanting). 135–140 days (from sowing)
  • Sowing Seasons: May–June (Kharif). Nov–Dec (Rabi)

 

Seed & Planting

  • Seed Rate: Normal: 350–400 g/ha. Hybrid: 100–150 g/ha
  • Spacing: 60 × 45 cm
  • Training/Pruning: Followed in indeterminate types
  • Staking: Required for indeterminate varieties
  • F1 Hybrid Coverage: ~33% of total tomato area (highest among vegetables)

 

Pest & Disease Management

Nutrient & Growth Regulation

  • Micronutrients: Boron (B) & Zinc (Zn) are critical
  • 2,4-D @ 2–5 ppm: Induces parthenocarpy and early fruit set
  • PCPA @ 20 ppm: Enhances fruit set and yield.

 

  • Common Physiological Disorders:
    • Fruit Cracking: Boron deficiency, moisture imbalance
    • Blossom End Rot (BER): Calcium deficiency + high temp
    • Puffiness: Due to poor pollination, extreme temperatures
    • Cat Face: Abnormal growth due to hormonal imbalance

 

Important Varieties

  • Introduced; Roma, Sioux, Tip Top, Best of All.
  • Selection; Improved Meeruti, Pant Bahar (Verticillium & Fusarium resistant). Arka Saurabh
