Digitaria Maniculata Stapf

Digitaria maniculata Stapf - Overview

Digitaria maniculata Stapf is a plant species belonging to the family Poaceae. This species is commonly known as Fingergrass or Smooth Fingergrass. It is native to Africa and is widely distributed in subtropical and tropical regions.

Appearance

The plant is an annual grass that grows up to 100 cm tall with long, slender leaves and green stems. The leaves are linear, flat or folded, and can grow up to 30 cm long and 1 cm wide. The inflorescence is a narrow, cylindrical panicle that can grow up to 15 cm long. The panicle consists of 12-27 spikelets, each containing several flowers, and has a greenish-white color. The seeds are small and brown, and they are slightly curved with a pointed tip.

Uses

Digitaria maniculata Stapf is used for medicinal purposes in several African countries such as Nigeria, Ghana, and Togo. In Nigerian traditional medicine, it is used to treat malaria, fever, and other common diseases. The plant extract is also used in cosmetics and hair care products. It is used as an ingredient in shampoos to treat dandruff and itchy scalp. Additionally, the plant is also grazed by livestock such as cattle and sheep.

In conclusion, Digitaria maniculata Stapf is a plant with several uses in traditional medicine and cosmetic products. Its unique appearance makes it stand out from other grass species. It is an essential plant in African countries where it is commonly found.

Light Requirements

Digitaria maniculata Stapf, commonly known as Finger-grass or Snapdragon grass, requires full sun to grow well. It tolerates partial shade, but it may not develop its ornamental features under such conditions. Therefore, it is recommended to plant the grass in areas with direct exposure to sunlight for at least six hours a day.

Temperature Requirements

Finger-grass is classified as a warm-season grass, which means that it requires warm temperatures to germinate and grow. The optimal temperature range for its growth is between 25°C to 35°C. It can tolerate high temperatures of up to 40°C, but it may develop growth problems if exposed to temperatures lower than 15°C or frost.

Soil Requirements

Digitaria maniculata Stapf thrives in various soil types, including sandy, loamy, or clay soils. The ideal soil for its growth should be well-drained, fertile, and slightly acidic (pH range of 6.0 to 6.5). Adequate soil moisture is also essential for better growth and development.

Cultivation Methods

Digitaria maniculata Stapf can be propagated through seeds or by dividing rootstocks. The plant thrives well in well-draining soils with pH ranging from 6.0 to 7.5. It requires full sun exposure to grow, although it can tolerate partial shade.

Watering Needs

Digitaria maniculata Stapf requires sufficient watering, especially during the growing season. Although the plant can tolerate short periods of drought, it is best to keep the soil moist at all times, mainly if grown in containers. Overwatering can cause root rot, and therefore, it's crucial to ensure proper drainage.

Fertilization

The plant requires occasional fertilization, especially if grown in nutrient-poor soils. Feed the plant with a balanced fertilizer during the growing season at least once every two months. Alternatively, you can apply organic matter to the soil to improve nutrient levels.

Pruning

Digitaria maniculata Stapf doesn't require regular pruning, although it's advisable to remove dead or diseased stems regularly. You can also trim the plant to maintain the desired shape and size. It's best to carry out pruning during the late winter or early spring before new growth appears.

Propagation of Digitaria maniculata Stapf

Digitaria maniculata Stapf, commonly known as the Fingergrass plant, is a famed species of grass originated from Africa. It is grown worldwide for both ornamental and medicinal purposes. The propagation of Digitaria maniculata Stapf depends on two popular methods of propagation: seed propagation and vegetative propagation.

Seed Propagation

Seed propagation is the most common method of propagating the Fingergrass plant. The seeds require a well-drained alluvial soil for proper germination. The seeds must undergo the process of scarification on their surfaces before sowing to alleviate the hard outer coat and allow water and air to penetrate for germination. The ideal time to sow the seeds is during the early rainy season, which should be followed by the appropriate water management practices. The total germination period ranges from 14 to 28 days, depending on the prevailing weather conditions.

Vegetative Propagation

Vegetative propagation is mostly used to increase the yield of the Fingergrass plant. It involves splitting the root structures or cutting the stalks to produce a clone that is a genetic replica of the mother plant. To split the root structure, the plant's crown is uprooted and divided into smaller segments containing healthy roots. These segments are then transplanted into another suitable bed and watered adequately. The other method of vegetative propagation involves cutting the stalks using a sharp sterilized knife and inserting the cuttings into a suitable bed with a 50:50 mixture of soil and sand. The cuttings must be watered appropriately to prevent dehydration while establishing in the new environment. Both methods generally produce a mature Fingergrass plant after approximately six weeks.

Disease Management

Digitaria maniculata Stapf, commonly known as Finger grass, is prone to various diseases. The common diseases that may affect this plant include rust, leaf spot, and smut. These diseases can lead to a reduction in plant growth and quality of yield. To manage rust and leaf spot, it is recommended to remove any infected plant debris and use disease-resistant cultivars. Additionally, regular fungicide sprays can mitigate the spread of these diseases. Smut cannot be controlled once the infection has occurred, so it is essential to remove and destroy any affected plants and their debris.

Pest Management

Finger grass can become infested with various pests that can cause significant damage, such as aphids, cutworms, and mole crickets. If you notice yellowing or browning of the grass, it may be due to an infestation of aphids. To control aphids, you may use insecticidal soap spray or neem oil. Cutworms chew through the base of the plant, causing it to wilt. To prevent cutworm infestation, use collars around the base of the plant. Mole crickets can cause grass to have brown spots, and their presence may be indicated by the presence of tunnels beneath the ground. Trapping or using insecticides can control the spread of mole crickets, and grass can recuperate after treatment.
