between the years 2013-2017 in Sarıkamış, Kars (NE Anatolia). The study area is dominated by a continental climate (with an average altitude of 2250 m), with long winters and short summers. The mean annual minimum and maximum temperatures, relative humidity, and total precipitation are: −8.1 and 15.6°C, 67%, and 575 mm, respectively. Soils of the experimental site are of volcanic origin and have low CaCO3 content. Seedlings grown in the greenhouse were transplanted to the study area in a randomized block design with three repetitions, as a total of 672 seedlings (14 mixture × 16 Scots pine seedlings × 3 replications) (No plant growth was observed in 100%DE, cancelled). They were planted at 1.5 × 3 m on 23 October 2013. Survival rates and height and stem diameter of seedlings were measured in the fall of 2017. Height and stem diameters of the seedlings were measured from the soil surface.
All the data were subjected to analysis of variance (ANOVA) and the significant means were compared by Duncan’s multiple comparison test method, performed using the SPSS Statistical Package v.20.0 (IBM 2011) at p≤0.05 level of significance, unless otherwise mentioned.
Effects of growing media on Scots pine seedlings (Pinus sylvestris L.) morphological properties are presented in Table 2. Height of Scots pine seedlings varied between 3.75-6.37 cm. The highest growth was observed in 6th, 1st, 9th, 13th, and 10th mixtures. As compared with the control (14th mixture),
