    • 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)

    Cause & Control

    Late Blight

    Phytophthora infestans – Copper oxychloride @ 3g/L + Bacteromycin 0.1g/L

    Damping Off (nursery)

    Pythium spp. – Seed treatment with Trichoderma viride (4g/kg) or P. fluorescens (10g/kg)

    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

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