  • 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. 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. Ventilation
  • 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
