Paspalum maritimum

Paspalum maritimum (Trin.) is a perennial grass species belonging to the Poaceae (grass) family. This species is native to tropical and subtropical coastal regions, particularly in South America and the Caribbean, where it plays a critical role in the natural vegetation of damp, saline-influenced environments.

The origin of Paspalum maritimum is tied to coastal tropical habitats. Its natural range encompasses areas with high humidity and consistent warmth. Unlike many other forage grasses, this species has evolved to tolerate the challenging conditions of coastal ecosystems, making it a specialized plant in its native range.

Botanically, the plant is characterized by its creeping or tufted growth habit. It features narrow, linear leaves and distinct inflorescences typical of the Paspalum genus, usually arranged in two or more terminal racemes. The root system is relatively shallow but fibrous, which is effective for rapid colonization of sandy or clay-based coastal soils.

Agricultural requirements for Paspalum maritimum are strictly centered on a tropical climate. It requires a long growing season with high temperatures and high annual rainfall to reach maximum productivity. The soil should be well-drained but capable of holding moisture. In cultivation, it is crucial to avoid cold stress, as this species lacks the physiological adaptations to survive freezing temperatures.

The primary economic use of this plant is as a source of forage for livestock in tropical pastoral systems. Key applications include:

• Extensive cattle grazing in tropical coastal zones.
• Soil stabilization and coastal erosion control.
• Use in biomass production for green manure in specialized tropical gardens.
• Maintenance of turf in non-decorative agricultural landscapes.

Regarding health management, Paspalum maritimum is susceptible to typical grass pathogens, including rusts and various leaf-spot fungi that thrive in humid environments. Pests such as leaf-eating insects and grasshoppers can cause significant damage if populations are not controlled. Integrated pest management strategies are recommended to maintain healthy and productive stands.
