In South Korea, experiments were conducted in hydroponic greenhouses aimed at distinguishing high-yielding, disease-resistant varieties and hybrids in hydroponic greenhouses suitable for the Uzbekistan market.
The research was conducted in 2015-2018 in a film hydroponic greenhouse built on the basis of South Korean technology at the "Center for Innovative Developments and Consultancy in Agriculture" at the Tashkent State Agrarian University. The experimental area is the Chirchik Highlands, characterized by high solar radiation, daily and seasonal temperatures, continental, dry and hot in summer, high humidity in spring, and cold hardiness in winter.
The hydroponic greenhouse is built on the basis of South Korean technology, the roof is arc-shaped, 7 sections, covered with polyethylene film, the area of the construction area is 5000 m2. Each piece was 8 m to 94 m long. There are aluminum curtains, nets on the right, left, back, and sides, and curtains on the right, left, back, and top that protect the plant from the heat of the sun.
The greenhouse has an automated control system consisting of fogging equipment that regulates air humidity, a ventilation system, sensors, and sensors that measure air temperature, humidity and heat. In addition, it has a heating system (working with gas and oil products), a boiler room, a drip irrigation system, water and mineral fertilizer storage tanks, and a water and mineral fertilizer mixing system.
Among the tomato hybrids studied, there are high-quality and high-yielding (yield 19.4-20.7 kg/m2) varieties resistant to fusarium wilt and cladosporiosis. It is stated that the share of the high yield is 93.6-93.9%, and the weight of one fruit is 178-180 g) Daphnis F1, Torri F1, and Pink Paradaes F1 hybrids were selected.
