Abstract :Due to its high organic matter content, sawdust can be used for soil amendment. This study investigated the effect of sawdust obtained from a furniture industry insert ignore into journalissuearticles values(Yildiz Integre Akhisar flakeboard); on grape yield and loam texture soil insert ignore into journalissuearticles values(Typic Xerofluvent); properties of a vineyard located in Saruhanlı District, Manisa, Turkey. In the trial, three groups with dry sawdust insert ignore into journalissuearticles values(10 t ha-1, 20 t ha-1; 30 t ha-1); was added to plots of vineyard while 0 t ha-1 or without sawdust addition was set up as a control group. All the 4 treatments were replicated three times insert ignore into journalissuearticles values(4×3);. Sawdust addition resulted in significant increase insert ignore into journalissuearticles values(p <0.05); of soil organic matter, total nitrogen, electrical conductivity insert ignore into journalissuearticles values(EC);, available Na, Ca, Mg, Fe, Zn, P, K, and Mn contents, moisture, saturation percentage, field capacity, wilting point, available water and aggregation percentage values compared with control group. Also, the soil pH, bulk density, and dispersion percentage significantly decreased with sawdust addition. However, there was no significant change in lime, available Cu contents, structure stability index, aggregate stability of the soil with sawdust addition. Compared with control group, addition of 20 t ha-1 and 30 t ha-1 of dry sawdust significantly increased the grape yield of the vineyard. The highest yield of 4.23 t ha-1 was recorded with 30 t ha-1 sawdust addition. Sawdust can be used as a soil amendment given its positive effects on some soil properties and grape yield of the vineyard. It is suggested that nitrogen immobilization from the soil by microorganisms due to sawdust’s high C/N ratio is a key consideration for its future use.
