Effect of Initial Seed Moisture Content on Emergence and Yield of Grain Sorghum
1971
Phillips, J. C. | Youngman, V. E.
Emergence and yield of grain sorghum (Sorghum bicolor (L.) Moench) were studied as affected by the moisture content of seeds at sowing time. Sorghum seed sown with 8% moisture content emerged less than seed sown with either 11 or 14% moisture. Low initial seed moisture content and low substrate temperatures resulted in delayed radicle protrusion from the pericarp as well as a decrease in seed respiration rate during imbibition. Effects on emergence were great enough to be reflected in grain yields, especially under dryland conditions.
