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

摘要

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 carriedout in the Korkyt Ata 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 ofthe 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, yieldof standard products, fruit taste and largest profit - was the Panekra hybrid. Lilos Fl, Maxitos Fl, Gravitet Fl, Klepton Fl, Esmira Fl and Clarabella Fl hybrids also had high productivity, good fruit quality and relatively high profit. These hybrids arerecommended for greenhouse soilless culture in PreAral area conditions.
