Corn tops sorghum in comparison trials
Abstract Not Available – First paragraph follows: Grain sorghum has been grown as the second crop in double crop systems in California agriculture for years. Its use has been marginally profitable, especially in occasional years with early, wet falls. Growers interested in greater profits began investigating the possibility of substituting early maturing corn varieties for grain production in place of sorghum. When grown as a full season crop, corn usually shows a yield advantage over grain sorghum. These comparisons by growers indicated that corn did have a potential yield advantage over sorghum as a double crop and also showed the ability to overwinter when early autumn rains made fall harvests impossible.
