Pigeon Pea (Cajanus cajan)
In this video, Colin Mitchell and Lindsey Richards from the Subtropical Soil Health Initiative discuss using Pigeon Pea (Cajanus cajan) as a cover crop option for hot and humid areas. Pigeon pea is grown around the world as a protein-rich food source. In the Rio Grande Valley of Texas and other subtropical areas, it can be used as a nitrogen-fixing cover crop that stands up well to extreme heat once established. Pigeon pea does a fantastic job of shading the soil in hot summers, provides bioavailable nitrogen for the next cash crop, and reduces both wind and water erosion. While Pigeon Pea currently has limited availability in the United States, it shows great promise as a cover crop option.
