Résumé
In this study which analyzes the effect of different tillage methods on planting success in arid and semi-arid area forestations, 12 different processes were tested. Within this scope, deep subsurface tillage in full range with double and triple ripper, top soil tillage with light and heavy disk harrow and gradoni type terrace making with two furrow plough processes were applied either singly or combined. In plantings, black pine (Pinus nigra Arnold), Taurus Cedar (Cedrus libani A. Rich.) and Gray Juniper tillers (Juniperus excelsa Bieb) were used. The experiment was formed in Karaman Ayrancı district, Akpınar –Çat region suitable to random blocks test pattern and with 3 iterations. In parcels in which processes were applied, species were represented with 20 saplings in each iteration and 2160 saplings were planted in total (3 species x 12 processes 3 iterations). At the end of first and second vegetation periods after planting, survival percent, sapling height, elongation of the terminal shoot and diameter stump height measurements were done. Data obtained were evaluated in SPSS statistics package program. According to Variance Analysis and Duncan test results, among processes taken to experiment, processes no 2 (double riper+gradoni terrace) and no 8 (triple riper+gradoni terrace) were included in the most successful five or six process and suggested for all the three species thinking that it would ne economic and enable application easiness. According to survival percent results obtained at the end of first two vegetation processes, first of all Gray Juniper and Taurus Cedar can be preferred in forestation in and around the experiment area due to high survival percent. Although Black pine has given 43% of survival percent as of the second year, considering its natural propagation, biological and silvicultural characteristics, Black pine should absolutely be planted in forestation of arid and semi-arid areas.
