Bu araştırma 2000 yılında Konya Hayvancılık Araştırma Enstitüsü tarlalarında beş sorgum-sudanotu melezi çeşidi (Elrey,Grass,Grazer,Jumbo ve Sweet) ile yürütülmüştür. Denemede çeşitlerinden elde edilen iki biçimdeki ortalama bitki boyu 215.53 cm (sweet)-231.02 cm (Jumbo); bitki ağırlığı 495.6 g (Elrey)-674.5 g (Sweet); sap çapı 0.99 cm (Elrey)-1.39 cm (Jum-bo); sap ağırlığı 406.8 g (Elrey)-537.0 g (Sweet); sap oranı % 74.7 (Jumbo)-%82.0 (Elrey); yaprak ağırlığı 88.7 g (Elrey)-153.0 g (Jumbo); yaprak oranı %15.5 (Grazer)-%25.2 (Jumbo); kuru madde oranı %27.73 (Sweet)-%34.55 (Elrey) arasında bulunmuş, toplam kuru madde verimi 4486.8 kg/da (Grass)-5745.2 kg/da (Jumbo) ve toplam yaş ot verimi 14641.3 kg/da (Grass)-19038.7 kg/da (Jumbo) arasında değişmiştir. Bir yıllık sonuçlara göre; verim ve ele alınan diğer özellikler için Konya ve benzeri ekolojilerde Jumbo ve Sweet sorgum-sudan otu melez çeşitleri ön plana çıkmışlardır.

This research was conducted with five sorghum-sudangrass hybrid cultivars (Elrey,Grass,Grazer,Jumbo and Sweet) at Animal Research Institute of Konya in 2000. Obtained data as average of two cutting summarised as follows; plant heights were 215.53 cm (Sweet)-231.02 cm (Jumbo); plant fresh weights were 495.6 g (Elrey) to 674.5 g (Sweet); stem diameters were 0.99 cm (Elrey)-1.39 cm (Jumbo); stalk weights were 406.8 g (Elrey) to 537.0 g (Sweet); stalk ratios were 74.7% (Jum-bo)-82.0% (Elrey); leaf weights were 88.7 g (Elrey) to 153.0 g (Jumbo); leaf ratios were15.5% (Grazer)-25.2% (Jumbo); dry matter ratios were 27.73% (Sweet) to 34.55% (Elrey). As total of two cutting green forage yields were 146410 kg.ha-1 (Grass) to 190380 kg.ha-1 (Jumbo) and dry matter yields were 44860 kg.ha-1 (Grass) to 57450 kg.ha-1 (Jumbo). According to results of one-year; Jumbo and Sweet c.v. can be shown to be suitable varieties as silage production with respect to yield and other observed characters in Konya Province and similiar ecologies.
