Description
Sudangrass (Sorghum sudenense Piper Stapf) is one of the most important annual fodder crops in Kuestan plain (Southwest of Iran). The plant has been cropped in the region for more than 25 years. However, the data are scant on the yield potential and management practices of different cultivars under these hot climates where the growing season ranges from 150 to 180 days. Kaschani and Bahrani (1985) in Ahvaz, and Summer et al. (1965) in California, respectively showed 400-600 kg/ha and 178.4 kg/ha of nitrogen as split application for irrigated sudangrass. Worker (1973) found that the total dry matter production of sudangrass and sudangrass hybrids was highest when harvested at the flowering stage. Crude protein percentage of these cultivars also decreased at this stage. Vidan is the only cultivar which used to be grown in the Khuestan region. But as the seeds of this cultivar were recropped every year, and no selections have been made through the years, its genetic characteristics have been lost. Therefore, it was necessary to reintroduce new cultivars for the region.
