The introduction of Sudan grass (Andropogon sorghum var.) into the United States took place less than nine years ago, but since then this crop has become widely known and its popularity is rapidly increasing. Sudan grass, being an annual, does not make a good pasture plant, but gives excellent results as a hay or soiling crop; it might also be successfully made into silage if mixed with a legume.
