Axonopus Compressus (sw.) P.beauv.

Overview:

Axonopus compressus, also known as flatgrass or carpetgrass, is a warm-season perennial grass that belongs to the Poaceae (grass) family. It is a hardy grass that grows well in warm, humid regions, particularly in sandy or clay soils.

Origin:

Axonopus compressus is native to the southeastern United States, Central America, and tropical South America. It has been introduced to other parts of the world, including Africa, Asia, and Australia, where it has become a common turf grass species.

Appearance:

Axonopus compressus is a low-growing grass with a carpet-like appearance. It has a thick and densely packed rosette of leaves that can grow up to 12 inches in height. The leaves are shiny and bright green, and the plant produces numerous greenish-white spikelets that are held on brownish spikes.

Uses:

Axonopus compressus is widely used as a turf grass in warm, humid regions. It is particularly popular for use on golf courses and lawns, where its ability to grow in shade and its tolerance to foot traffic make it an ideal choice. It is also used for erosion control, as a forage for livestock, and as a cover crop.

Light Requirements

Axonopus compressus prefers full sunlight exposure for optimal growth and development. In low light conditions, the plant tends to become leggy and thin, with poor foliage growth.

Temperature Requirements

The ideal temperature range for the growth of Axonopus compressus is between 20-35°C. The plant can tolerate occasional temperature drops of up to 5°C but prolonged exposure to temperatures below 15°C can lead to stunted growth, yellowing of leaves and even death.

Soil Requirements

The plant thrives in well-drained soils with moderate fertility. Axonopus compressus has moderate tolerance for acidic soils, with a pH range of 4.5 to 7.5 being suitable. The plant can grow in both sandy and loamy soils, and it is especially useful in soils with poor structure and low nutrient levels, as it has the ability to improve soil fertility by fixing atmospheric nitrogen.

Cultivation of Axonopus compressus

Axonopus compressus can be propagated through seeds or vegetative methods such as stolons or plugs. Optimal planting time is during the rainy season when the soil is moist.

Watering Needs of Axonopus compressus

Axonopus compressus prefers well-draining soil that is kept consistently moist. Regular watering is necessary during dry spells and high temperatures to avoid wilting and stress.

Fertilization of Axonopus compressus

Regular fertilization is essential for the healthy growth of Axonopus compressus. A balanced fertilizer with equal parts of nitrogen, phosphorus, and potassium is recommended every three months. Alternatively, frequent application of organic matter such as compost can also provide a sufficient source of nutrients.

Pruning of Axonopus compressus

Pruning is essential to keep Axonopus compressus healthy and promote new growth. Regularly trimming the tips of the grasses can encourage fuller growth, reduce bald spots, and prevent the accumulation of thatch. It is ideal to keep the grass between 2-3 inches in height. Remove all dead matter and debris, which can attract pests and diseases.

Propagation of Axonopus compressus

Axonopus compressus (Sw.) P.Beauv. is a commonly used turfgrass species that belongs to the family Poaceae. The propagation of this plant can be done by both vegetative and seed propagation methods.

Vegetative Propagation

Vegetative propagation of Axonopus compressus can be done by using stolons, rhizomes, or sods. Stolons and rhizomes are the most commonly used methods in which fragments of the plant are severed and planted directly into soil. Aquatic Axonopus compressus species reproduce through both stolons and seeds.

Seed Propagation

Seed propagation of Axonopus compressus is a viable option, but with lower germination rate. Seeds should be planted in coarse soils to enable easy germination and should be covered with about 1cm of soil. Germination should take place in about two weeks. Seed propagation is also used to maintain Axonopus compressus accessions as seed storage and exchange is often carried out amongst these accessions.

Disease Management

Axonopus compressus is susceptible to several diseases that could significantly reduce its productivity. Some of the most common diseases affecting the plant include:

• Anthracnose
• Rust
• Fungal leaf spots

To manage these diseases, it's important to follow strict cultural practices such as proper sanitation, crop rotation, and planting healthy seeds and seedlings. Another effective way of preventing diseases is to minimize stressors such as overwatering and over-fertilization, which weaken the plant's defenses. Lastly, applying fungicides and other chemical treatments can significantly reduce disease occurrence and severity.

Pest Management

Several pests can cause significant damage to Axonopus compressus, with some of the most common ones being:

• Cutworms
• Mole crickets
• Armyworms

Effective pest management for Axonopus compressus includes implementing cultural practices such as removing debris and weeds that could harbor pests. Additionally, planting companion plants that repel pests can also help. Applying chemical treatments such as insecticides and pesticides also provides effective control measures for pests. It is important to carefully follow application guidelines and safety measures to prevent any hazards to humans and the environment.
