Sorghum (S. bicolor Moench 'Pride P130'), wheat (T. aestivum L. 'Neepawa') and barley (H. vulgare L. 'Galt') were harvested at 1 wk intervals on dry and at Lethbridge, Alberta [Canada], in 1976 and 1977 and separated into leaves, stems, heads and seed. Whole-plant yields were higher in 1976 than in 1977 and sorghum whole-plant yields were higher than barley or wheat in both years. Sorghum grain yields were similar to those of barley, but were greater than those of wheat. Although sorghum is about 40 days later maturing than barley or wheat, its whole-plant and filling-period durations were not very different from the other 2 crops. Sorghum used water more efficiently than wheat or barley under drought conditions. The biggest disadvantage of present sorghum hybrids apparently is slow growth in spring.
