Bu araşt ı rma Ankara Üniversitesi, Ziraat Fakültesi, Tarla Bitkileri Bölümü deneme tarlas ı nda 1998 ve 1999 y ı llar ı nda yürütülmü ştür. Ara şt ı rman ı n amac ı Ankara sulu ko ş ullar ı nda denemeye al ı nan en uygun silajl ı k sorgum çeşidi ve gübre dozunun belirlenmesidir. Ara şt ı rmada Early Sumak, Leoti ve Rox silajl ı k sorgum çeşitleri ile 0, 5, 10, 15 kg N/da azotlu gübre kullan ı lm ışt ı r Araşt ı rmada gübre dozlar ı n ı n, bitki boyu, sap kal ı nl ığı , yeşil ot verimi, kuru ot oran ı ve verimi, ham protein oran ı ve veriminde etkisi her iki y ı lda da önemli bulunmu ştur. En fazla yeş il ot verimi ilk y ı lda 3395,1 kg/da, ikinci y ı lda da 3006,1 kg/da ile 15 kg N/da azot dozundan elde edilmi ştir. Çeşitler aras ı nda yeşil ot verimi bak ı m ı ndan farkl ı l ı k bulunmam ışt ı r.
This research was conducted at experimental fields of Department of Agronomy, Faculty of Agriculture, University of Ankara in 1998 and 1999. The aim of the research is to determine the conveinent sorghum variety for silage and nitrogen dose under irragated conditions in Ankara. In the research Early Sumak, Leoti, Rox varieties and 0, 5, 10 and 15 kg/da nitrogen doses were used as materials. Effects of nitrogen doses were found statistically significant for plant height, stem thickneSs, green yield, hay yield ratio, raw protein ratio and raw protein yield in both years. The highest green yield was obtained from 15 kg Nida with 3395.1 kg/da in 1998 and 3006.1 kg/da in 1999. Differences among varieties for green yield were found not significant.
