Results of experiments with sweet sudan and sudan 23 and suggestions for planting
by Fred N. Briggs
| Full text HTML  | PDF  
Not available – first paragraph follows: Widespread interest in Sweet Sudan has been aroused among California growers of Sudan grass. This variety was developed by Dr. B. E. Karper and Dr. J. B. Quinby of the Texas Agricultural Experiment Station from a cross between Leoti, a sweet sorghum, and Common Sudan grass followed by backcrosses to Sudan.
