Tomato production is concentrated mainly in the south of Russia. It is unevenly distributed across regions. There are separate zones and centers of production in which the main volumes of marketable products are produced. The largest tomato production zone in the Rostov region is the territory with the center in the village of Krivyanskaya in the vicinity of the city of Novocherkassk. The main volumes of early tomatoes are grown here in spring greenhouses. Products are exported to the industrial centers of the Middle Belt and to Moscow. Regular deliveries for many years, excellent taste and attractive appearance became the basis for the emergence of a special brand called “Tomato of Krivyanskaya”. On the territory of the zone, various elements of tomato cultivation technology were gradually worked out, and the assortment was improved. In different historical periods, there was a change in these components of tomato production. An analysis of the changes that took place shows that they went in the direction of intensifying production with a bias towards the development of chemicalization and the development of innovative methods of tomato culture. Only the soil and climatic conditions of the zone remained unchanged. However, in recent years, the indicators of natural soil fertility and the quality of irrigation water have deteriorated. The negative impact of monoculture on the size and quality of products has increased. Among the external signs characteristic of the fruits produced is the elongated top of the fruit when using various varieties and hybrids. Usually, the elongation of the top is a consequence of the use of special agrochemicals that contribute to fruit set, but the presence of this feature in cultivated varieties and hybrids. Local technology is also characterized by early cultivation of seedlings with its subsequent conservation and thickened placement of plants in greenhouses. In the future, there is a planned transition to adaptive, environmentally friendly technologies with the biologization of its main elements and the cultivation of varieties and hybrids with integrated resistance.
Key words: tomato, technology, variety, hybrid, Rostov region.
