Abstract :In this study, biogas production efficiencies of mixtures obtained by adding corn silage insert ignore into journalissuearticles values(CS); to citrus industrial wastes at different ratios were determined. Orange insert ignore into journalissuearticles values(OJPW); and tangerine processing juice wastes insert ignore into journalissuearticles values(TJPW); insert ignore into journalissuearticles values(crusts and shells); were selected as materials in the study. 25%, 50%, 75% of CS was added to these selected wastes. Changes in the obtained mixture chemical properties insert ignore into journalissuearticles values(dry matter, dry organic matter, crude ash, crude protein, crude oil, Acid Detergent Fiber insert ignore into journalissuearticles values(ADF);, Neutral Detergent Fiber insert ignore into journalissuearticles values(NDF););, biogas production and methane content in the biogas were investigated. The results of the study showed that the highest crude protein content was found in 100% TJPW insert ignore into journalissuearticles values(10%);, raw fat percentage in 100% TJPW insert ignore into journalissuearticles values(5.14%);, dry matter content in 100% CS insert ignore into journalissuearticles values(93.56%);, ADF in 100% CS insert ignore into journalissuearticles values(22.74%); and the NDF in a mixture of 25% OJPW + 75% CS insert ignore into journalissuearticles values(45.08%);. The highest methane production was determined for a mixture of 100% TJPW and 50% TJPW + 50% OJPW insert ignore into journalissuearticles values(0.46 m3 kg-1 ODM);. Also the highest biogas production was determined in a mixture of 50% OJPW + 50% TJPW insert ignore into journalissuearticles values(0.90 m3 kg-1 ODM);. The mixing of CS in TJPW and OJPW reduced significantly the production of methane and biogas in the mixture. As a result of the statistical analysis, significant differences insert ignore into journalissuearticles values(P≤0.05); were found in both methane and biogas production of agricultural wastes.
