Digitaria Eriantha Steud. Subsp. Pentzii (stent) Kok

Origin

Digitaria eriantha Steud. subsp. pentzii (Stent) Kok, commonly known as Pentz's couch grass is a perennial grass from the family Poaceae. It is native to southern Africa, particularly in Namibia, South Africa, and Botswana.

Common Names

Aside from its scientific name, Digitaria eriantha Steud. subsp. pentzii is also known by several common names across its range, including Pentz's couch grass, Pentz's finger grass, kambro (Afrikaans), and inkunzi yomuthi (Zulu).

Uses

This plant has several uses in traditional medicine and agriculture. Its roots and leaves have been used to treat various conditions such as coughs, colds, and fever. It has also been used to enhance milk production in lactating animals. In agriculture, Pentz's couch grass is used for grazing and makes good quality hay. It is sometimes used as a cover crop as it can suppress weed growth when planted densely.

General Appearance

The plant Digitaria eriantha Steud. subsp. pentzii is a tufted grass with an erect or sprawling habit that can grow up to 1 meter tall. The leaves are elongated, hairless, and have a rough texture with a pointed tip. Its inflorescences are finger-like and can grow up to 20cm long, with branches that spread out horizontally. The flowers are small, with a spikelet that is surrounded by a few hairs at the base. It has a fibrous root system that allows it to grow in sandy or loamy soils. Its color ranges from green to light brown.

Light Requirements

Digitaria eriantha Steud. subsp. pentzii (Stent) Kok prefers full sun or partial shade and grows well in both conditions. However, it's worth noting that direct sunlight is best for the growth of this plant species.

Temperature Requirements

Digitaria eriantha Steud. subsp. pentzii (Stent) Kok is an adaptable plant that can grow in a wide range of temperatures. However, the ideal growth temperature range is between 15°C and 30°C. This makes the plant species a good option for growing in subtropical and tropical regions.

Soil Requirements

The plant species prefers well-drained soil with a neutral to slightly acidic pH level (6.0 to 7.5). The soil should also be rich in organic matter. Sandy loam or loam soil types are preferred for the growth of Digitaria eriantha Steud. subsp. pentzii (Stent) Kok. However, the plant species can tolerate a wide range of soil types including clay soils as long as they are well-drained.

Cultivation Methods of Digitaria eriantha Steud. subsp. pentzii (Stent) Kok

Digitaria eriantha Steud. subsp. pentzii (Stent) Kok, commonly known as "Pangola grass," is a warm-seasoned grass species native to Africa. Cultivation of this plant requires moderate temperatures, full sunlight, and well-draining soil. For optimal growth, the soil pH level should be between 5.5 to 7.5. The plant is propagated through vegetative means such as stem cuttings or runners.

Watering Needs of Digitaria eriantha Steud. subsp. pentzii (Stent) Kok

The Pangola grass requires moderate watering. Overwatering the plant can lead to root rot. An optimal watering frequency for this plant is once a week, or when the topsoil feels dry to the touch. During dry seasons, additional watering may be required.

Fertilization of Digitaria eriantha Steud. subsp. pentzii (Stent) Kok

Applying fertilizers to the Pangola grass plant can improve its growth and development. Adding nitrogen-rich fertilizers such as urea or ammonium sulfate will aid in the plant's growth. The fertilizer should be applied during the growing season, ideally after the first mowing.

Pruning of Digitaria eriantha Steud. subsp. pentzii (Stent) Kok

Pruning of the Pangola grass is essential to maintain its dense growth and lush appearance. Regular mowing of the grass is recommended, preferably when the grass reaches a height of 3-4 inches. Avoid mowing lower than this height, as it can damage the plant. Mow the plant to a height of 1-2 inches for optimal growth.

Propagation of Digitaria eriantha Steud. subsp. pentzii (Stent) Kok

Digitaria eriantha Steud. subsp. pentzii (Stent) Kok can be propagated both sexually and asexually. The plant is commonly propagated through seed and vegetative methods.

Seed propagation

The plant produces a large number of seeds that can be collected from the mother plant and sown in containers or directly into the soil. The optimal time for seed collection is when the seeds are ripe and begin to fall off the plant. The seeds should be stored in a cool and dry place until the planting season or until the soil is moist enough to support germination. The seeds should then be planted at a depth of about 1-2 cm in nutrient-rich soil. Proper watering and fertilization will promote healthy plant growth and development.

Vegetative propagation

Vegetative propagation of Digitaria eriantha Steud. subsp. pentzii (Stent) Kok can be done through stem cuttings, root division, and layering. Stem cuttings are taken from healthy, mature plants and planted in nutrient-rich soil. Root division involves separating a mature plant's roots into two or more sections and planting them in separate containers. Layering involves burying a section of the plant's stem in the soil while it is still attached to the plant. After a few weeks, roots will develop from the buried stem section and can be cut away from the mother plant and replanted.

Disease Management:

Digitaria eriantha Steud. subsp. pentzii is known to be affected by various fungal diseases such as leaf spot, rust, and smut. These diseases can be controlled by a proper and regular fungicidal spray. The use of resistant varieties is also an effective management strategy. It is recommended to remove infected plant material and destroy it to prevent the spread of the disease.

Pest Management:

The most common pests that affect Digitaria eriantha Steud. subsp. pentzii are grasshoppers, armyworms, and cutworms. These pests can be managed by using appropriate insecticides. To prevent infestations, it is recommended to practice proper field sanitation by removing weed hosts that serve as breeding places for the pests. Natural enemies such as birds and predators should also be encouraged to help control the pest populations. Crop rotation is an effective management strategy as it helps to break the pest cycle.
