This type of tomato is especially attractive to consumers and suitable for marketing, use in salads, sauces, and home or industrial canning.
Optimal tomato varieties can vary depending on the environment and the goals of the grower or gardener. Hybrid lines such as Optimal F1 or the Optima Tomato from Seminis, recognized for its high performance, great resistance to diseases, and medium to large-sized fruits. It is important to select the variety best suited to the specific conditions of each orchard, considering climate, soil type, and sun exposure.
Among the most sought-after characteristics of the optimal tomato, the following stand out:
- Homogeneous shape and size
- Thin but resistant skin, of uniform tone
- Dense pulp, juicy and tasty
- Good preservation capacity after harvesting
- Low amount of seeds and tendency to avoid the appearance of hollow heart
- Resistance to cracking and common diseases such as mildew, powdery mildew and fusarium
Diversity of varieties and growth types
Tomato varieties can be grouped according to their for Growth is available at:
- Determined (of bush): They stop growing at a certain height, producing most of their fruit in a short period of time. They are ideal for small spaces and do not require intensive training.
- Indeterminate (vines): They grow and bear fruit throughout the season, and can reach over 2 meters. They require training and pruning.
Variety Optimal It is usually classified as indeterminate, which makes it a vigorous and very productive plant, capable of reaching more than 2 m in height, with medium to large sized fruits, thin skin and great flavor.
Optimal environmental conditions for tomato cultivation
The tomato plant requires balanced environmental conditions to fully realize its productive and qualitative potential. The main factors to control are detailed below:
Temperature
- La optimum development temperature ranges between 20 and 30°C during the day and between 12 and 17°C at night.
- Temperatures above 30–35°C They negatively affect fruiting and can discolor the fruits.
- Values ​​below 12°C can stop growth and ruin fertilization.
- Frost is lethal for the plant and should be avoided at all times.
RH
- The ideal range is between 60% and 80%.
- Excess humidity increases the risk of fungal diseases and fruit cracking.
- Low humidity makes pollination difficult and can result in deformed fruit.
Luminosity
- Tomato is sun lover: requires a minimum of 6 to 8 hours of direct sunlight per day for full development.
- Low light weakens vegetative development and increases susceptibility to pests and diseases.
Land
- Prefer loose soils, rich in organic matter, with good drainage.
- Ideal texture: sandy loam or siliceous-clayey.
- pH slightly acidic to neutral, although it tolerates slightly alkaline values ​​if the soil is well sanded.
- Avoid waterlogged or very clayey soils.
- The tomato species is tolerant, within greenhouse crops, to salinity relative to water and soil.
Fertilization and soil preparation
- Soil fertility must be taken care of with organic contributions (compost, manure or green manure) and balanced mineral fertilizers in nitrogen, phosphorus, potassium, calcium and magnesium.
- El match It is essential in the initial stages of rooting and flowering.
- El Calcium prevents blossom end rot of the fruit, while the potassium improves quality, flavor and firmness.
- Fertilizer application should be based on a soil analysis, adapting the dosage to the actual needs of the crop and avoiding excesses that could disrupt growth or contaminate the environment.
Optimal tomato planting and development
Seedbed preparation and transplantation
Sowing seeds is usually done in protected seedbeds, especially if there is a risk of low temperatures or frost. Once the seedlings They reach about 15-20 cm and develop 4-5 true leaves, they are transplanted to the final location or to pots, as long as the conditions are adequate.
- Before the transplant It is recommended to harden the plants by gradually reducing watering and exposing them to the outdoors for a few hours a day, so that they can adapt to the environment.
- To plantations in the field or greenhouseTransplanting is usually done when the risk of frost has disappeared. In colder areas, plastic bottles or cloches can be used to protect the young plants.
Plantation frame
- Recommended distance: For indeterminate varieties such as Optimum, 0,5 meters between plants and 1–1,5 meters between rows.
- For varieties with less development or medium size, 2 plants can be placed per square meter (1 m x 0,5 m).
- En pots, it is recommended to use containers of at least 20 liters with good drainage.
Tutoring
- Es essential in indeterminate growth varieties.
- Tutors can be from cane, wood, wire or polypropyleneThe most common system is individual staking per plant, with regular tying as the plant grows.
- The tutored improves aeration, avoid contact of the fruit with the ground y facilitates harvesting and other cultural works.
- In large areas, systems of hangers, mesh or metal structures can be used.
Pruning and defoliation
- La formation pruning After transplanting, remove the axillary shoots (suckers) and lower leaves to promote vertical growth, aeration and prevent diseases.
- In tomatoes Cherry Several stems can be left, but for large varieties 1 or 2 are recommended.
- El detailed It should be frequent (weekly in summer, every 10-15 days in winter), making clean cuts to prevent the entry of diseases.
Irrigation in optimal tomato cultivation
Irrigation is one of the most decisive factors in the success of tomato cultivation. It must be constant and moderate, adapting to the stage of development and environmental conditions.
- The tomato needs moisture in the root y sun on the leaf, so wetting the foliage should be avoided to avoid promoting diseases.
- Recommended irrigation systems They are dripping and exuding, allowing a regular and precise supply.
- The frequency varies depending on the climate, soil type, and plant development: watering in pots should be more frequent than in soil.
- El water stress or irregular watering can cause cracks in the fruit or physiological problems such as blossom end rot.
A basic principle is soak the substrate deeply (at least 25 cm), which favors deep roots and plants that are more resistant to drought.
Optimal fertilization and manure in tomato
- Fertilization should begin just before transplanting and continue throughout the entire growth cycle, increasing potassium intake during fruiting to improve fruit quality.
- In pots or urban gardens, fertilization should be even more frequent, as nutrients are depleted more quickly than in open soil.
- El homemade compost It is ideal, and comfrey leaves can be added to the compost to increase the potassium content.
- El padded with dry plant remains helps maintain moisture and reduces the appearance of weeds.
Specific care and maintenance
Pruning and thinning
- Regularly removing axillary shoots and old leaves promotes the development of the main stem and improves aeration.
- It promotes the production of larger and tastier fruits.
Weed control
- Mulching is the best strategy for reduce competition for water and nutrients.
- Weeding by hand or with tools should be done carefully to avoid damaging the surface roots.
Control of pests and diseases
- La regular observation is key to detecting anomalies.
- La crop rotation and choosing resistant varieties are effective preventive methods.
- Aromatic plants such as basil They can repel pests such as aphids.
- If pests appear, resort to ecological remedies such as soapy water, nettle or tansy infusions to treat aphids and other insects.
- In case of fungal diseases: sulfur, Bordeaux mixture or homemade solutions such as diluted milk are effective against powdery mildew and downy mildew.
Main pests in tomatoes
- Red spider, whitefly, aphid, thrips, tuta, leaf miners, caterpillars and nematodes
- Act with chromatic traps, ecological products or authorized chemicals depending on the degree of infestation
Main diseases
- Oidium: Yellow stains and white ash; treat by removing affected areas and applying sulfur or diluted milk.
- Mildew: Oily stains: remove affected areas and apply copper, Bordeaux mixture, or approved fungicides.
- Blossom end rot: Calcium deficiency can be prevented by spraying with milk or calcium chelates.
- Fruit cracking and sunburn: Irregular watering and excessive sun exposure; moisturize and protect properly.
Crop rotation and good practices
- Avoid planting tomatoes after other solanaceous crops (potatoes, eggplant, peppers) to reduce pest and disease pressure.
- Return tomatoes to the same plot only after 3–4 years.
- Choose crops such as legumes, onions, cabbages or grasses as predecessors.
Optimal tomato seed selection and management
- Select certified seeds and adapted to the climate and soil is essential.
- Compare varieties based on hardiness, productivity, and flavor.
- Research performance records and consult with reliable suppliers.
