Study Notes
Tomato Production
- Tomatoes are a widely grown horticultural crop, used for fresh consumption and processing (e.g., canning, juicing).
- The majority of tomato production occurs outdoors.
- China produces the most tomatoes globally (35 million tons/yr, 25% of world production).
- Other major tomato-producing countries include the European Union, United States, Turkey, Egypt, and India.
Greenhouse Tomato Production
- Greenhouses were initially used for out-of-season tomato production.
- Improvements in greenhouse technology (hydroponics) led to year-round production and higher-quality tomatoes compared to field-grown ones.
- Spain has the largest area dedicated to greenhouse tomatoes (8,000 hectares).
- Other major greenhouse tomato producers include Turkey, France, Netherlands, Italy, and the US.
Tomato Types
- Various commercial greenhouse tomato varieties exist, categorized by fruit size.
- Beefsteak: Large fruit ( >180g), 3.5-4.5 Brix, high yield (100%).
- TOV (Tomatoes-on-vine): Medium fruit (~100-200g), 4-5 Brix, moderate yield (80-90% of beefsteak yield).
- Cherry/Cocktail: Small fruit (15-80g), high Brix (5-7%), lower yield (40-60% of beefsteak).
- Grape: Very small fruit (8-15g), highest Brix (7-8%), lowest yield (25-50% of beefsteak).
Hydroponic Tomato Systems
- Tomatoes are mainly grown in slab/bag or Dutch/BATO bucket hydroponic systems.
- NFT and raft systems are used less frequently in commercial settings.
Tomato Production Stages
- Tomato production involves propagation, vegetative growth, flowering, pollination, and fruit set/growth.
- Stages after fruit set occur largely in parallel.
Tomato Propagation & Seedling Growth
- Tomatoes are propagated from seed (4-6 days to germinate at 72-75°F).
- Grafted tomatoes require seed propagation of rootstock and scion prior to grafting.
- Seedlings require good photosynthetic light (supplemental light useful in winter).
- Nutrients (0.8-1.2 mS∙cm−1 initial 10 days, increasing to 2.0-2.2 mS∙cm−1 before planting) are essential.
Vegetative Growth
- Environment (light, temperature, CO2) and culture (mineral nutrition, irrigation) variables influence vegetative growth.
- Vegetative growth (pruning: sucker removal, leaf removal, topping) is maintained throughout.
Flowering, Pollination & Fruit Set
- Flowers develop after formation of several true leaves.
- High fertilizer/temperature/low light delay flowering.
- Pollination occurs after flower opening (hormones, bees, hand-pollination can provide needed assistance).
- Fruit development begins after successful pollination and fertilization of ovules.
- Fruit growth is stimulated by seed hormones.
- Maintaining appropriate fruit load is required (large fruit=4-6 fruits, smaller=5-8 fruits).
Tomato Crop Nutrition
- Tomato nutritional requirements change throughout the production cycle.
- Altering the nutrient solution can optimize different growth stages.
Nutrient Management for Different Tomato Stages
- Different nutrient solutions are needed at different phases of growth (e.g., seeding, transplanting).
Potassium and Nitrogen Importance
- Nitrogen (N) and potassium (K) are critical for growth and development.
- Potassium uptake is especially high in fruit development.
Calcium's Role
- Calcium is crucial for fruit development, as fruit cells require high calcium for expansion.
CO2 Enrichment, Temperature & Light
- CO2 enrichment up to 1000ppm is commonly used, but the system must be ventilated to prevent waste.
- Target day/night air temperatures are 75°F/65°F.
- Managing adequate light (12+ mol∙m−2∙d−1) using supplemental lighting is essential.
Humidity/VPD
- Management of humidity (55-90%, dependent on temperature) and VPD (0.3-1.3 kPa) is key for avoiding diseases and optimal nutrient uptake.
Crop Steering for Tomatoes
- Crop steering (to promote vegetative or generative growth) is used for targeted fruit yield optimization.
- Factors that influence growth: genetics (cultivars), age, moisture/irrigation, humidity, temperature, light.
Tomato Pest and Disease Management
- Common pests/diseases include whitefly, thrips, aphids, spider mites, botrytis, Erwinia, Pythium, powdery mildew, bacterial wilt, and bacterial spotting.
- Proper management strategies are required.
Tomato Harvesting
- Seven stages classify tomato ripeness (immature, mature green, breaker, turning, pink, light red, red).
- Harvests occur at the appropriate color stage.
Pepper Production (Hydroponics)
Cucumber Production (Hydroponics)
Lettuce and Greens Production (Hydroponics)
Herb Production (Hydroponics)
Strawberry Cultivation (Greenhouse)
Mushroom Production (Hydroponics)
Aquaponic Plant Production (Hydroponics)
