Purpose: This study has a sweet thin (Sorgum bicolor) grown in the Bornova hole where the Mediterranean climate dominates. In order to determine the productivity of the dried substance (KM), the silage mining characteristics and the quality of feed, in the summer of 2013 and 2014, the second product cultivation conditions, the Ziraat Faculty of the University of Ege has been carried out for two years in the Bornova experimental fields of the Department of Farm Plants.

Objective: This study was conducted in order to determine dry matter (DM) yield, silage fermentation and some forage quality components of sweet sorghum (Sorghum bicolor var. saccharatum) grown in summer second crop production period, on the experimental fields of Faculty of Agriculture, Ege University under Mediterranean ecological conditions of Bornova-Izmir during two years in 2013-2014. Material and Methods: Two different sweet sorghum cultivars (Keller and Rio cv.) were used as crop material. Sweet sorghums were cut three different harvesting stages (panicle emergence, anthesis and doughy), and, field experiment were conducted with three replicates. Some traits were tested in the experiment such as DM yield, sugar content, silage pH, and crude protein content, cell wall properties. Results: Results indicated that, there were significant differences between harvest stages and sweet sorghum varieties in terms of above-mentioned characteristics. Delaying harvest stage affected positively on DM yield and fermentation quality but not forage characteristics (metabolisable energy and NDF, ADF). It was also concluded that Keller cv. was superior to Rio cv. with regard to abovementioned traits.
