Sudan Grass in Iowa
Is Version Of
Sudan grass is one of the very best non-leguminous emergency hay crops available for use in Iowa. It has been under observation at the Iowa Agricultural Experiment station during the past eight years. Over 250 experimental seedings have been made with it in the past five years. It surpasses millet or oat hay from the standpoint of yield and is about the same in feeding value as these crops, as well as timothy. It is not a legume and is surpassed In feeding value, pound for pound, by clover, alfalfa or soy beans. Since it is not a legume it does not take its nitrogen from the air. It is therefore not recommended as a regular crop in the rotation, but as an emergency or catch crop which can be used to advantage for hay, pasture or soiling. Being an annual, it does not compete with clover, alfalfa, or timothy, which live for more than one year.
