Axillare creeping pea

Macrotyloma axillare, commonly known as axillare creeping pea, is a robust perennial legume belonging to the Fabaceae family. This creeping or climbing plant is highly valued in tropical agro-ecosystems for its role in pasture improvement and soil nitrogen fixation.

Originating from tropical Africa, this plant has been successfully introduced to other tropical and subtropical regions globally, including Australia and parts of South America. It is recognized for its ability to persist in various environmental conditions while providing consistent biomass for grazing animals.

The plant features trifoliate leaves and axillary inflorescences with yellow-green flowers. Its growth habit includes long, trailing stems that can root at the nodes, making it an excellent ground cover that helps stabilize soil and reduce moisture loss, effectively competing with weeds.

Cultivation requires well-drained soils and a warm climate with sufficient rainfall during the growing season. While it is tolerant of various soil types, phosphorus fertilization is often necessary to maximize productivity. Proper seed inoculation with compatible rhizobia is crucial for early establishment and vigorous growth.

The primary use of Macrotyloma axillare is as a high-protein forage crop for cattle and sheep, as it remains palatable throughout the season. It is also used as a green manure or cover crop to enrich soil fertility. Although generally disease-resistant, growers should monitor for root rot under waterlogged conditions and manage pests that may affect leaf health.
