Tifleaf III Pearl Millet is well adapted to sandy and loamy soils. It is not adapted to clay or heavy soils. Pearl millet has no risk of developing prussic acid, but it usually will not make as much total biomass as the various sorghums and sudans. Pearl millet can grow to 6 feet or taller under good conditions but is generally medium in height when compared to other warm-season grass cover crops. Expect about 60 days of growth before it goes reproductive. Seeding rate was 16 pounds per acre.
The plots were drill planted in 7.5 inch rows in a clean-tilled and culti-packed seedbed on May 16, 2017, at the Noble Research Institute Headquarters Farm in Ardmore, Oklahoma, on a Weatherford fine sandy loam. Planting depth was shallow, about 0.5 inch, in a dry seedbed, and 2.33 inches of rain fell over the next three days. There was no fertilizer, insecticide or herbicide applied to the crops, and pigweed pressure in the field was very heavy. Rainfall was below average after establishment.
