The Batavian lettuce Sveva Cortese is a relatively new variety, having been bred by Sativa Seeds Italy in the early 2000s. It is a cross between the Batavian lettuce varieties Batavian Blonde de Paris and Batavia Reine des Glaces. The goal of the breeding program was to develop a Batavian lettuce variety that was resistant to lettuce tipburn, a common physiological disorder that can cause the leaves of lettuce plants to become brown and necrotic at the tips.
Sveva Cortese was released to the market in 2005 and has quickly become a popular variety among both commercial and home growers. It is known for its excellent taste and texture, as well as its resistance to lettuce tipburn and other diseases.

 

Open Batavia type. Perfect for the baby leaf market, Suitable selection for the greenhouse and open field cultivation, and good growth in low temperatures.

High resistance to bolting. In the center of Italy, cultivation is recommended in the autumn and spring periods, and with care, it is also possible to cultivate in the summer period.

Leaves are slightly blistered, with an indented edge, blond colored and they make a heavy and voluminous tuft. The variety presents good organoleptic characteristics. It is used for tuft and leaf-cutting harvesting.

Cortese Lettuce is one of the most famous types of Batavia lettuce in Italy, it’s one of the most popular types of lettuce globally and the most widely consumed due to its distinctive shape that is used in decorating many dishes, as well as for its wonderful taste, in addition to its high nutritional benefits.

Sveva Cortese is a semi-head lettuce variety, meaning that the leaves form a loose head. The leaves are large and slightly blistered green, with a slightly wavy margin. The heads are typically 10-12 inches in diameter and weigh 1-2 pounds. Sveva Cortese is a slow-bolting variety, meaning that it does not go to seed as quickly as some other lettuce varieties. This makes it ideal for both spring and fall production.

Seeding and growing

  Germinate directly in the soil (Open Field)

If you plant the seeds directly in the soil, you will need a stock of seeds of about 2 kg/acre.

  • sowing depth: 1 cm
  • sowing distance among the rows: 40 cm
  • sowing distance on the row: 25 cm

 

  1. Prepare the soil mixture and plant the seeds at a depth of 1 cm in the soil, where the seeds must be covered with soil for the success of the germination process (Mixture of 70% cocopeat – 10% vermiculite – 5% perlite – 15% plant compost is preferred. It can increase the proportion of compost to 30% when the plant grows and adding an amount of organic fertilizer to the soil when planting lettuce so that the roots do better into the soil.
  2. Spray the soil and seeds with water using a spray bottle or a spray bottle and cover them with a plastic box or a plastic bag to speed up the germination process, do not forget to make holes in the plastic box so that the seeds can breathe. Germination takes about 3 to 15 days.
  3. Examine the seeds once every 3 days and make sure that the soil has sufficient moisture for the seeds until germination. After germination, the plastic bag is removed and the plant is placed in a sunny place, don’t forget to water them well.

Germination in seedling trays or small containers:

It is preferable to plant in this way to achieve the highest rates of growth and to provide the appropriate conditions for seed germination in a better way, and this also encourages the seeds to grow better.

  • Prepare the soil mix and plant the seeds at a depth of 1 cm in the soil, where the seeds must be covered with soil for the success of the germination process (a mixture of 70% cocopeat – 10% vermiculite – 5% perlite – 15% plant compost is preferred). By adding the amount of organic fertilizer to the soil when planting Lettuce so that the roots grow better into the soil.
  • Spray the soil and seeds with water using a sprayer and cover them with a plastic box or a plastic bag to speed up the germination process, do not forget to make holes in the plastic box so that the seeds can breathe. Germination takes about 3 to 15 days.
  • Examine the seeds once every 3 days and make sure that the soil has sufficient moisture for the seeds until germination. After germination, the plastic bag is removed and the plant is placed in a sunny place, paying attention to watering well.
  • After 4 leaves appear, so that there are 3 real leaves, the plant can be moved to larger containers so that there is more space for the seeds to grow and mature.

 

Growth stage:

It takes about 60 days for lettuce to reach maturity, and during this stage, lettuce needs some important factors affecting their growth.

Therefore, care must be taken to ensure that the soil is rich in various nutrients, such as vegetable compost.

Harvesting

  • Lettuce can be harvested quickly as a batch by cutting the whole head.
  • You can harvest the entire plant including the roots and you should keep it in cold temperatures, just above freezing (above 0º C) is ideal, this way lettuce can stay fresh for up to three weeks.
  • Don’t let the lettuce freeze, if frozen, the leaf will wilt quickly.
  • Lettuce requires humidity to avoid drying out, but condensation or heavy moisture on the leaves is detrimental.
  • The best thing that producers can do to avoid condensation is to keep temperatures very consistent and to process lettuce as little as possible.

General Info:

  • Lettuce is one of the most popular and extensively used crops in the world. It is grown well in almost any gardening system, whether hydroponic, aquaponic, or traditional soil and is known to have a high market demand.
  • Hundreds of lettuce varieties are grown around the world, with the most common varieties being Red and Green Romaine, Iceberg, Oak Leaves, Green Leaf, and Mesclun mixes.
  • Both high temperatures and dry soil can trigger plants to bolt and flower, turning the leaves bitter and stopping leaf production.
  • Lettuce is vulnerable to post-harvest wilting if the harvesting techniques are handled roughly during the process.
  • Water makes up over 95% of raw lettuce. As a result, eating lettuce hydrates the body. Although drinking liquids is necessary, water in foods can also significantly contribute to hydration.
  • Lettuce is a source of vitamin A, which plays a role in eye health. Vitamin A can reduce a person’s risk of cataracts. Vitamin A also helps prevent macular degeneration.
  • Extracts of multiple lettuce types have also been shown to promote sleep. Until further research is conducted, it’s unknown if the lettuce in its natural form can produce a similar effect.
  • The nutritional content of lettuce varies across varieties.
  • Lettuce contains a significant amount of vitamin A, along with small amounts of vitamin C and iron.
