Effects of different soil preparation techniques on the Anatolian Black Pine (Pinus nigra Arnold subsp. pallasiana (Lamb.) Holmboe) regeneration

In this study, the effects of different soil preparation treatments on regeneration of black pine success were examined and some suggestions were given according to the results. Twelve sample plots were randomly set in the research area. The size of each sample plot was 4 m(2). Sample plots were seeded equally with a total number of 2304 (48 seeds per m2) seeds in April 2012. The number of surviving seedlings was recorded every month from May to November in 2012. Surviving seedlings were recorded again in November 2013 and growths of thirty seedlings which are selected randomly from the all sample plots were examined. It was found that soil treatment with machine was more successful in regeneration at semi-arid regions like Cerkes-Turkey. Plowing equipment as mechanical soil cultivation has more economically advantageous in first years. However, the success and quality of seedlings were better in soil preparation with ripper equipment compared to plowing.
