    2. 2. Tomatoes• Tomatoes are the number one product grown in high tunnels• High Market demand• Very nutritious• Cost effective• Many uses• Profitable• Easily grown for the most part• Large selections of varieties
    3. 3. Tomato Culture• Determinant vs indeterminate• Plant spacing 18 inches to 3 ft,• Plant on beds, or flat• Soil Nutrition is extremely important• Disease control• Irrigation• Weed control
    4. 4. “Book Values” for Tomatoes N P KPlant Part -------- lb per ton F.W. ------------Fruit 3.4 0.4 6.0Vines 2.6 0.4 3.4 Total 6.0 0.8 9.4 A 50 ton yield/A would require: ( 20 Lbs Plant) 300 lbs N/A 40 lbs P/A (92 lbs P2O5) 470 lbs K/A (564 lbs K2O)
    5. 5. Soil Nutrient Research 2008 Fertilized Plots Cobra Tomatoes 0-6 inch soil depth N P KBefore Season 263 252 1349After Harvest 26 235 173
    6. 6. Ventilation
    7. 7. Leaf mold on tomato (Fulvia fulva) Highly dependent on high RH and temperature for disease development Conidia germination requires RH > 85% and an optimal temperature 68-77°F Disease rarely occurs below 50°F Conidia can survive at least 1 year in the soil Numerous strains Sharon Douglas, CAES
    8. 8. Four stages of disease management 1. Pre- High Tunnel Establishment 2. Pre- Season 3. Transplant Production 4. Crop Production
    9. 9. Irrigation• How long would you like to go without water?• 10 hours of drought can delay maturity 2 days• Drastically reduce quality• Soil nutrients can only be taken up in solution• Fertilizer and water .
    10. 10. Tomato Evaluation• How do you evaluate a high tunnel tomato? – Size ? – Color? – Yield ? – Earliness? – Firmness ? – Heirloom ? – Flavor ? – You make the Call
