Abstract
This study was conducted in Bornova experimental fields of Department of Field Crops, Faculty of Agriculture, University of Ege, Turkey during 2015 and 2016, in order to determine the effects of treated sewage sludge on yield and quality of vetch + barley mixture. The experimental design was in complete randomized blocks, with four replications. In the trial some characteristics such as plant height, botanical composition, fresh herbage yield, dry matter rate, dry matter yield, the rates of crude protein and crude ash, the yields of crude protein and crude ash, NDF and ADF rates were determined. The results showed that plant height, botanical composition, fresh herbage yield and dry matter yield were significantly affected by the applications. In the study which the highest vetch and barley plant height and dry matter yield were obtained with sewage sludge applications of 20 and 30 t ha-1, the highest vetch botanical composition was obtained with control and mineral fertilizer applications. Sewage sludge application of 10-30 t ha-1 gave the highest barley botanical composition. Dry matter rate, crude ash rate and yield, crude protein rate and yield, NDF and ADF rates were not affected by mineral fertilizer and sewage sludge applications.
