Özet
In this study, as plant materials, Prima and the Early Sweet
table grape varieties grown in the soilless culture system were used. In
these varieties, three different growing media namely, Cocopeat,
Perlite:Peat, Basaltic pumice and 10 and 20 clusters/vine crop loads for
Prima; 10 and 15 clusters/vine crop loads for Early Sweet variety were
tested. In order to determine the effects of the applications,
phenological stages, grape yield and some quality characteristics were
observed. On both varieties, Cocopeat and Perlite:Peat media were found
superior to the Basaltic Pumice in terms of cluster, berry and juice
characteristics. The highest grape yields were in the 20 cluster/vine
crop loads for Prima and with 15 cluster/vine crop loads for Early Sweet
varieties, grown in Perlite:Peat medium by 42 t ha⁻¹ and 38 t ha⁻¹
grape yield, respectively. The obtained cluster weigts from the
experimental field were in extra class according to the TS-101
standards, Total Soluble Solids and maturity index values were higher in
Cocopeat and Perlite+Peat media than that of basaltic pomza for both
varieties. In general, analysis of the leaf samples taken at two
different sampling time from both varieties showed lower values than the
optimal limits of N, P, K, Ca, Fe and Zn, but were higher than the
limit values of Cu and Mg elements. As nutrient element level of the
fruit samples, it is observed that P, K, Ca and Na values were lower;
Cu, Mn, Fe and Zn values were higher than the limit values of elements. As a result of considering these
evaluations, it was found that 20 cluster/per plant for Prima, 15
cluster/per plant for Early Sweet grown in the Perlite:Peat medium was
appropriate for obtaining sufficient grape yield and quality level.
