The variability of tomato crops in different climatic zones of Ukraine, reflecting the peculiarities of thermal and moisture regimes was evaluated. Levels of fluctuations in harvests of tomatoes in Ukraine, their dynamics were investigated and simulated data trend lines. The main factors of yield increase are: an introduction of new, more productive varieties, the introduction of cultivar zoning, in which accommodation of varieties with different ripening were performed in accordance with relevant agro-climatic resources of the territory to the biological characteristics of this crop. The highest yield of tomato in area of South Steppe of Ukraine was concluded.
Keywords: Solanum lycopersicum L., yields variability, yield trend, thermal regime, moisture content
