Digitaria Comifera Pilg.

Overview of Digitaria comifera Pilg.

Digitaria comifera Pilg. is a species of perennial grass native to Africa, particularly found in Tanzania. It is commonly known as the finger grass, button grass, or comb finger grass.

General Appearance of Digitaria comifera Pilg.

The finger grass has a tufted growth habit and can grow up to 120 cm tall. It has a dense root system and produces short rhizomes. Its leaves are green and narrow, measuring up to 30 cm long and 6 mm wide. The finger grass has green or purple-coloured spikes, which are usually compressed and grow up to 20 cm long.

Uses of Digitaria comifera Pilg.

The finger grass is an important forage crop for livestock, particularly for goats, sheep, and cattle. It is also used for soil conservation and erosion control, and as a cover crop to improve soil fertility. In traditional medicine, the finger grass is used to treat urinary tract infections, dysentery, diarrhea, and stomach ache. It is also used as a herbal remedy for fever, headache, and joint pain.

In some areas, the finger grass is cultivated as an ornamental plant, for its attractive, spiky inflorescences, which retain their shape even when dried. The seeds of the finger grass are also used as bird feed.

Overall, the finger grass is a versatile plant, with a range of uses in agriculture, medicine, and ornamental horticulture.

Light Requirements

Digitaria comifera Pilg. is a plant that requires full sun to thrive. It needs at least 6 hours of direct sunlight to sustain its growth, which should not be obstructed by shading from taller plants or trees. Lack of adequate light may result in stunted growth or even the death of the plant.

Temperature Requirements

Digitaria comifera Pilg. is a warm-season grass that grows best in high-temperature environments. Its optimal growth range falls between 25 to 35 degrees Celsius. However, it can tolerate temperatures as high as 45 degrees Celsius. The plant cannot survive in frosty conditions, so its growth may be halted or even completely destroyed when temperatures drop below 10 degrees Celsius.

Soil Requirements

The plant prefers a well-drained soil that is rich in organic matter and nutrients. It grows best in soils with a pH range of 6.0 to 7.5. Digitaria comifera Pilg. can tolerate soils that are clayey, loamy, or sandy. However, the soil should not be waterlogged, as this may cause root rot and hinder the plant's growth. In areas where the soil is not fertile, occasional fertilizer application is recommended for optimal growth.

Cultivation Methods for Digitaria Comifera Pilg.

Digitaria comifera Pilg., commonly known as the Little Millet, thrives well in warm weather and requires a moderate climate to grow healthily. The plant prefers a well-draining and fertile soil that is rich in organic matter. Since it is a rainfed crop, the best time for cultivation is between June and July, during the start of the monsoon season.

Watering Needs for Digitaria Comifera Pilg.

Digitaria comifera Pilg. requires sufficient water to grow well, particularly during the seedling stage. During the early phase of growth, frequent watering is recommended, but the frequency can be reduced as the plant matures. However, the soil should never dry out. It is important to ensure that the plant receives an adequate amount of water, especially during the flowering stage when water stress can affect the yield of the plant significantly.

Fertilization of Digitaria Comifera Pilg.

Digitaria comifera Pilg. requires proper fertilization to grow well. Using organic manure is an excellent option for this plant. The manure can be mixed with the soil before sowing, or as topdressing during the growth period. Additionally, the application of balanced fertilizers such as NPK would significantly improve the yield and quality of the crop. Nitrogenous fertilizers can be added to the soil during the tillering stage to boost growth.

Pruning Digitaria Comifera Pilg.

Pruning the Little Millet is not necessary for growth. However, it is essential to remove any dead or diseased leaves and stalks to reduce the chances of pest infestation. Also, careful monitoring of the plant's growth is essential to determine if there is an overgrowth of branches that may impact the growth and yield of the crop. Regular weeding and trimming of overgrown branches will ensure the Little Millet grows well and produces a healthy yield.

Propagation of Digitaria comifera Pilg.

Digitaria comifera Pilg. is a perennial grass native to Africa. This plant can be propagated by using the following methods:

Seed propagation

The most common method of propagating Digitaria comifera Pilg. is by seed. The seeds should be collected at the end of the growing season when they are mature. The seed should be cleaned, and any debris or chaff removed. Moist stratification of the seed at 5°C is beneficial for germination rate. A period of cool and damp weather helps seeds germinate. Seeds should be sown in a well-draining soil and kept moist. Germination will occur in 7-14 days. Seedlings should be thinned to a spacing of 10-15 cm.

Vegatative propagation

Digitaria comifera Pilg. can also be propagated by dividing the plant clumps. This method is best done in early spring, before new growth appears. Dig up the clump and divide it into smaller sections. Ensyring each section has plenty of roots and replant into prepared holes. Keep the soil moist and cover with a light mulch. New growth will appear within 4-6 weeks.

Disease Management

Digitaria comifera Pilg. is a relatively disease-resistant plant. However, some fungal diseases may occur, such as leaf spot and rust. To manage these diseases, it's essential to maintain proper plant hygiene. Ensure that any dead or diseased plant material is removed and destroyed. The use of a preventive fungicide may also be helpful, especially during periods of high humidity.

Pest Management

Several pests may affect Digitaria comifera Pilg. These pests include grasshoppers, aphids, and spider mites. Grasshoppers are the most common pests, and they can cause significant damage to the plant. To manage grasshoppers, it's advisable to use biological control methods that involve natural predators such as birds, frogs, and toads. Insecticidal sprays may also be helpful.

Aphids and spider mites are relatively easy to control with insecticidal soap, horticultural oil, or neem oil. Regular monitoring of the plant is essential to detect any pest infestations early. If the infestation is severe, it's recommended to hire a professional pest control company to eliminate the pests safely and effectively.
