The Successfulness Of Sawmilling Small-Sized Roundwood In Croatia Part II - Common Walnut (Juglans Regia L.)

This research is focused on Small-Sized Roundwood yield factors of Common walnut (Juglans regia L.). 60 piecess Small-Sized Roundwood were classified in groups according to diameter 15 to 24 cm and sawed by live sawing technique into unedged sawn boards with nominal thickness of 25 mm. All sawn boards were processed into dimension stocks and raw parquet staves by rip-cross sawing. Volume yield of the Small-Sized Roundwood processing into dimension stocks and raw parquet staves was in the range 17.01% to 52.14%. Quality yield coefficient of the roundwood processing into dimension stocks and raw parquet staves was in the range of 0.34437 to 0.98897 or 475.23 EUR/m3 to 1364.77 EUR/m3 of dimension stocks and raw parquet staves. Log value yield coefficient was in the range of 0.12577 to 0.50172 or 173.56 EUR/m3 to 692.37 EUR/m3 of the Small-Sized Roundwood. The results indicate a possibility of rational successfulness processing of the researched Common walnut Small-Sized Roundwood in sawmills.
