Columbus grass, a newly introduced forage crop, is a perennial species from the genus Sorghum. It is similar to Sudan grass, i.e., to hybrids between forage sorghum and Sudan grass. This paper deals with a 2-year comparative study of the performances of Columbus grass (Sorghum almum Parodi) and Sudan grass (Sorghum sudanense Pers.) grown under the agroecological conditions of the Vojvodina Province (Serbia). Basic biological characteristics and plant requirements for growing conditions are reviewed. Regarding yield performance and forage quality, Columbus grass was not superior to the conventionally grown forage crops, Sudan grass, forage sorghum and silo corn. Yield of green forage was found to depend significantly on stand density and climatic conditions of the year of growing. For humid years such as 2001, row distance of 25 cm and seeding rate of 25 kg/ha are recommended. For dry years such as 2002, the recommended figures are 50 cm and 10 kg/ha, respectively. Under the conditions of the Vojvodina Province, which are semiarid to arid in some years, the stand longevity of Columbus grass of three years may be an advantage in relation to the annual forage crops (Sudan grass, forage sorghum, silo corn). The study provides an answer as to the status of Columbus grass in the domestic production of animal feed.
