Study of Growth, Yield, and Yield Quality Indicators of Tomato Hybrids in Hydroponic Systems under Greenhouse Conditions

The main goal of the research was to study greenhouse tomato hybrids under hydroponic greenhouse conditions and to enhance the agro-economic properties
of tomato hybrids, offering farmers the hybrid that ensures high efficiency
of tomato cultivation under hydroponic greenhouse conditions. During the
vegetation period, phenological observations, biometric measurements, and
crop counting were performed. Producing and selling vegetables in the local
market is the primary activity of greenhouses and tomatoes occupy a significant
place in vegetable production. In recent years, various varieties and hybrids
have been imported into Armenia, most without testing. Tomato cultivation
in greenhouses occupies a leading place in Armenia. The greenhouse tomato
hybrids Merlis, Plumola, and Endeavor were researched.
