Characteristics of the Uno Rosso F1 tomato and cultivation techniques for the hybrid

The Uno Rosso F1 tomato, described as having a mid-early ripening period, is intended for outdoor cultivation. Its uniform fruiting allows for mechanized harvesting.

Advantages of a hybrid

The Uno Rosso F1 tomato variety is characterized by high yields and a mid-early ripening period. From planting to harvest, it takes 97-100 days. The leaves of the determinate bushes provide excellent protection from direct sunlight.

The plants bear round, intensely red tomatoes weighing 55–60 g. With increased soil moisture, the fruits retain their shape and are not prone to cracking.

The fruits, regardless of the sowing time, contain a stable amount of dry matter at a level of 4.9–5.5 Brix.

The harvested crop can be stored for 20 days and tolerates long-distance transportation well. The hybrid's characteristics indicate resistance to fungal diseases of nightshade crops (verticillium wilt, fusarium wilt, nematodes, and alternaria).

Reviews from vegetable growers cultivating this hybrid note the excellent taste of the tomatoes. In cooking, the tomatoes are used for preserving whole fruits, making sauces, and preparing various dishes.

Stem formation

Growing the Uno Rosso hybrid is cost-effective both in open ground and greenhouses. The tomato is capable of producing fruit in any conditions. When planted in greenhouses, the plants take up little space.

This hybrid is highly productive, so proper training and staking of the bushes is sufficient to achieve maximum yield. Tomatoes can be grown on a single stem, and it's advisable to combine the initial removal of side shoots with tying them to a support.

Excess shoots are removed by hand when they reach a length of 4-5 cm. At this point, side shoots are easily removed, and the wounds in the leaf axils heal quickly. If side shoots are removed promptly, stumps are not left behind. If a shoot is very overgrown, it's best to leave a portion of its base when removing it.

Open wounds on the stem are most often affected by gray mold. All trunk shaping procedures should be carried out only in the absence of excessive humidity and rain. It is recommended not to water the plants or apply fertilizer the day before.

Forming a bush with two stems at once significantly inhibits the plant's development. Therefore, the tomato plant should first be given the opportunity to establish itself.

Bushes are trained into a single stem in various ways, always leaving at least two reserve shoots for continued growth. Proper bush training has a positive effect on the quality of the fruit.

Cultivation techniques for hybrids

Uno Rosso tomatoes are grown using seedlings. Seeds purchased from specialist companies do not require additional treatment to ensure simultaneous sprouting.

Place the seed material into a container with prepared soil or substrate at a depth of 1 cm, water it with warm water using a spray bottle and cover it with film.

When one or two true leaves have formed, transplanting is done. Peat pots can be used for this purpose, as they make it easy to transplant the seedlings to their permanent location.

Caring for seedlings includes timely watering, providing light and heat conditions, and periodic fertilizing with complex fertilizers.

Before planting in the ground, plants are hardened off for 7-10 days, taken outside to adapt to the new conditions, constantly increasing the time from 15-30 minutes to several hours.

Compost is added to the prepared holes, the seedlings are planted, and watered with warm water. Plant care involves loosening the soil to maintain moisture balance and allow air to reach the root system.

During the growing season, mineral fertilizers containing potassium and phosphorus are required for normal plant development. The nutrient content of the soil can be increased by adding chicken manure.
