Variety Trial on Tomato Hybrids in Greenhouse Conditions of the Prearal Area of Kazakhstan

One of the most important factors in the intensification of greenhouse tomato production is the introduction of new high-yielding hybrids which are adapted to new technologies and unfavorable climatic conditions. The present investigation was carried out in the Korkyt Аta Kyzylorda State University greenhouse between 2010 and 2015, to study the performance of different tomato hybrids in terms of growth, yield and quality inside the greenhouse in the PreAral area conditions in Kazakhstan. Seventeen tomato hybrids selected from the Netherlands, Israel and Russia were grown on a substrate of sawdust in the conditions of the extended culture. Based on the results obtained, the most productive hybrids and those best adapted to the climatic conditions of the area are identified and the fruits’ quality assessment and cost-effectiveness analysis are given. The best yield and fruit quality results were obtained from hybrids from the Dutch selection. The best variety for all indicators - productivity, yield of standard products, fruit taste and largest profit - was the Panekra hybrid. Lilos F1, Maxitos F1, Gravitet F1, Klepton F1, Esmira F1 and Clarabella F1 hybrids also had high productivity, good fruit quality and relatively high profit. These hybrids are recommended for greenhouse soilless culture in PreAral area conditions.
