Digitaria Decumbens Stent - Description

Digitaria decumbens Stent is a perennial grass that is commonly known as a Pangola grass. This grass originates from South Africa; however, it has established itself in various other areas across the globe, including Southeast Asia, South America, and the Caribbean.

Appearance

The Pangola grass is a fine, dense grass with a wiry stem that measures approximately 1m long. In optimal growing conditions, the grass can develop a thick mat that measures about 30cm high and forms a turf-like cover. The leaves of the Pangola grass are smooth and have dark green coloration on the upper surface with a lighter shade of green on the underside.

Uses

Pangola grass has become incredibly popular in the agricultural industry because of its ability to withstand extended periods of drought and its tolerance to heavy grazing. It is a highly nutritious grass that is ideal for livestock production as it stimulates weight gain and milk production in animals. Additionally, it has silage- and hay-making potential and is used for erosion control as well.

Besides its application in agriculture, the Pangola grass is utilized in landscaping design, particularly within low-traffic areas. It is often planted on golf courses as it requires minimal maintenance, resulting in cost savings, and it provides short, manicured turf.

Furthermore, the Pangola grass also has medicinal properties as it is believed to contain antibacterial and anti-inflammatory agents. Native healers in South Africa use the grass to prepare remedies for a wide range of ailments, including diarrhea, stomach aches, and burns.

Light Requirements

Digitaria decumbens Stent requires full sun to partial shade for optimal growth. This means that the plant can tolerate some shade during the day but it also requires a certain amount of sun exposure. It is best to plant these grasses in areas where they can receive direct sunlight for at least 6 hours daily.

Temperature Requirements

Digitaria decumbens Stent thrives in warm climates and does not tolerate cold temperatures well. The ideal temperature range for this plant is between 21-30°C (70-86°F). The plant will not grow well in areas with temperatures below 10°C (50°F) or above 35°C (95°F).

Soil Requirements

Digitaria decumbens Stent grows well in a range of soil types as long as they are well-draining. However, the plant prefers soils that are loamy and rich in nutrients. A pH range of around 5.5-7.0 is also ideal for optimal growth. It is important to avoid planting this grass in areas with compacted or waterlogged soils.

Cultivation Methods

Digitaria decumbens Stent, commonly known as Pangola grass, is a warm-season grass that grows best in tropical and subtropical regions. It thrives well in well-drained, fertile soils with a pH range of 5.5-6.5.

The best cultivation method is to sow the seeds directly in the field at a depth of 1-2 cm. The ideal time to plant is during the rainy season when sufficient moisture is available to support germination and growth. Prepare the field by removing any weeds and debris and plow the soil to a fine tilth. Broadcasting is the recommended method of sowing, and the seed rate is 2-4 kg per hectare.

Watering Needs

Proper watering is essential for the optimal growth of Pangola grass. Water the grass immediately after planting and ensure that the soil remains moist during the germination period. After the grass has established, reduce the frequency of watering, but ensure that the soil is not allowed to dry out completely.

The watering frequency and amount of water depend on the soil type, weather conditions, and the stage of growth of the grass. Typically, Pangola grass requires about 25 mm of water per week, either from rainfall or irrigation during the hot and dry seasons.

Fertilization

Pangola grass is a heavy feeder and requires regular fertilization to maintain its growth and quality. Conduct a soil test to determine the nutrient status and apply the required fertilizers accordingly.

Apply nitrogen fertilizers at a rate of 60-100 kg per hectare annually in split doses during the growing season. Also, apply phosphorus and potassium fertilizers at a rate of 60-80 kg per hectare annually, depending on soil test results.

Pruning

Pruning is an essential management practice that promotes vigorous growth and improves the quality of Pangola grass. Regularly mow the grass to maintain a height of 5-7 cm, or as per the requirement of the livestock being fed.

Avoid cutting the grass too short as it can lead to stress and reduce the productivity of the grass. Remove any weeds or diseased plants regularly to prevent the spread of infection and maintain the health of the grass.

Propagation of Digitaria decumbens Stent

Digitaria decumbens Stent, commonly known as Pangola grass, is a warm-season perennial grass that belongs to the family Poaceae. It is widely used as a forage crop for livestock because of its high yield potential and nutritional value. Among the different methods of propagation, the most common ones are seed propagation, vegetative propagation, and sod transplanting.

Seed Propagation

Pangola grass can be propagated by seeds, but this method is less commonly used as compared to vegetative propagation. The seeds should be sown at a depth of 1-2 cm in well-prepared seedbeds during the early spring or late summer. The seedbed should be constantly irrigated to keep it moist until the seedlings reach a height of 5-10 cm. After that, the watering should be done as per the requirement. The seedlings can be transplanted to the main field after 8-12 weeks of sowing when they reach a height of 15-20 cm.

Vegetative Propagation

Vegetative propagation is the most common method used for propagating Pangola grass. It involves using stem cuttings or sprigs from a mature plant and planting them in the soil. The cuttings should be taken during the early spring or late summer when the plants are actively growing. The cuttings should be 10-20 cm long and have at least 2-3 nodes. They should be planted at a spacing of 30-60 cm in well-prepared soil that is rich in organic matter. The soil should be kept moist until the cuttings establish roots and start growing.

Sod Transplanting

Sod transplanting is another method used for propagating Pangola grass. It involves transplanting small pieces of sod from a mature plant to a new location where the grass is to be propagated. This method is commonly used for establishing turfgrass or lawns. The sod should be cut into small pieces of about 5-10 cm square, with at least 2-3 growing points. The sod should be planted immediately in well-prepared soil and should be kept moist until it establishes roots and starts growing.

In conclusion, Pangola grass can be propagated by seed, vegetative, or sod transplanting methods. Among these methods, vegetative propagation is the most common and preferred one. Proper care should be taken during the propagation process to ensure the successful establishment of the grass.

Disease and Pest Management for Digitaria decumbens Stent

Digitaria decumbens Stent, also known as pangola grass, is a popular forage grass that is widely used for livestock feed and erosion control. However, like all plants, it is susceptible to certain diseases and pests that can significantly reduce its yield and quality. Here are some common diseases and pests that might affect the plant and ways to manage them:

Diseases

Leaf spot: This fungal disease is characterized by small, round lesions on the leaves that can merge and cause larger spots. It can cause defoliation and reduce the yield and quality of the forage. To manage this disease, you should avoid overhead irrigation, remove infected plant debris, and apply fungicides if necessary.

Rust: This fungal disease causes orange or yellowish-brown spots on the leaves, stems, and seedheads. It can also reduce the yield and quality of the forage. To manage rust, you should remove infected plant debris, reduce nitrogen fertilizer application, and apply fungicides if necessary.

Root rot: This disease is caused by various fungi that attack the roots of the plant and cause stunting and yellowing of the foliage. To manage this disease, you should avoid overwatering, improve soil drainage, and plant in well-drained soil. Applying fungicides might also help.

Pests

Cutworms: These pests are the larvae of various moth species that feed on the stem and roots of the plant, causing wilting and stunting. To manage cutworms, you should use physical barriers, such as collars, around the base of the plant and apply insecticides if necessary.

Armyworms: These pests are the larvae of moths that feed on the foliage and can cause defoliation and reduced forage quality. To manage armyworms, you should monitor the plant periodically, use pheromone traps to detect the presence of moths, and apply insecticides if necessary.

Mites: These tiny pests feed on the sap of the plant and cause yellowing and stunting of the foliage. To manage mites, you should avoid over-fertilization and over-irrigation, use pest-resistant cultivars, and apply miticides if necessary.
