The leaves are elongated, linear-lanceolate, and measure about 6-20 cm long and 5-20 mm wide. The inflorescence is a panicle that is up to 50 cm long, with branches that are slender and somewhat spiky. The spikelets are about 3 mm long and have a palea and lemma that are usually brownish in color.
Common Names
The plant is commonly known as the Lineated Panicgrass or the Striped Panicum. In some regions, it is also referred to as the Striped Finger Grass, the Tropical Panicum, or the Panic Veldt Grass.
Uses
Panicum lineatum Schumach. has many practical uses. In some African countries, the plant is used as animal feed, particularly for grazing livestock such as cattle and sheep. It is also used in traditional medicine to treat ailments such as fever, anemia, and stomach issues. Additionally, the plant has ornamental value and is used in landscaping design.
Light Requirements
Panicum lineatum Schumach. will grow best with full sun exposure. It requires at least six hours of direct sunlight per day to maximize growth.
Temperature Requirements
The ideal temperature range for Panicum lineatum Schumach. to grow is between 20°C to 30°C. It cannot tolerate frost and any temperatures below 10°C will cause damage to the plant. It is best suited to warm climates and warm seasons.
Soil Requirements
Panicum lineatum Schumach. prefers well-drained soils with a pH range of 5.5 to 7.5. It can tolerate moderate salinity and is well adapted to sandy soils. The plant requires moderate levels of soil fertility, with a need for nitrogen, phosphorus, and potassium nutrients.
Cultivation Methods
Panicum lineatum Schumach. is a hardy grass that grows well in warm and temperate climates. It thrives in well-drained soils with a pH of 5.5-6.8. The plant should be grown in areas that receive plenty of sunlight and have good air circulation. It can be propagated by seeds or cuttings. Planting should be done during the rainy season to help the plant establish itself.
Watering Needs
Watering should be done regularly to keep the soil moist. Panicum lineatum Schumach. prefers moderate water levels and can tolerate periods of drought. Over-watering should be avoided as it may lead to root rot or fungal diseases. It is recommended to water the plant early in the morning or late in the evening when temperatures are cooler.
Fertilization
The plant requires regular fertilization to enhance its growth and development. Use of organic fertilizers such as manure, compost, or bone meal is recommended. Fertilizers should be applied during the rainy season and mixed with the soil to avoid burning the roots. Application rates depend on the age and size of the plant. A soil test can be conducted to determine the soil nutrient content and the appropriate fertilizer ratio to use.
Pruning
Pruning is not necessary for Panicum lineatum Schumach. However, it is advisable to remove any dead or damaged leaves to prevent the spread of diseases. The plant can also be trimmed to control its size and maintain a desirable shape. Any pruning should be done during the dry season to minimize damage to the plant.
Propagation Methods of Panicum lineatum Schumach.
Panicum lineatum Schumach. is a perennial plant that belongs to the family Poaceae. The plant has rhizomes that make it easy to propagate by vegetative means. Propagation of Panicum lineatum Schumach. can be done through seed or vegetative means.
Propagation by Seed
Propagation of Panicum lineatum Schumach. through seed is achieved by collecting mature seeds when they are fully ripe. The collected seeds are then cleaned to remove any debris and stored under dry conditions until planting time. The ideal planting time for the seeds is during the rainy season when the soil is moist. Before planting, the seeds can be scarified or stratified to enhance germination. Sowing can be done directly into the field in rows or broadcasted.
Vegetative Propagation
Propagation of Panicum lineatum Schumach. through vegetative means can be achieved through rhizome division or stem cuttings. Rhizome division is done by digging up the plant and separating the individual rhizomes. The separated rhizomes are then planted immediately into the field or pots.
Stem cuttings are taken from a healthy plant and cut into pieces of about 10 cm in length. The cuttings are then inserted into the soil to root. To improve rooting, the cuttings can be treated with rooting hormones. After roots have formed, the cuttings can be transplanted into pots or field.
Overall, Panicum lineatum Schumach. is relatively easy to propagate, and the use of rhizomes and stem cuttings ensures that plants with the same genetic makeup are produced.
Disease Management
Panicum lineatum Schumach. is a hardy and resilient plant and is not typically prone to many diseases. However, certain environmental factors such as high humidity, excessive moisture, and poor air circulation can lead to the development of fungal infections. The most common fungal diseases that affect Panicum lineatum Schumach. are leaf rust and smut.
Leaf rust can cause yellow to brown spots on the leaves, which eventually turn into small holes. The best way to manage leaf rust is to remove and discard infected leaves and plants. Fungicides can also be used as a preventative measure.
Smut is another fungal disease that can cause black, sooty growths on the plant's stems and leaves. This disease is best managed by removing and discarding infected plants and using fungicides to prevent the disease from spreading.
Pest Management
Panicum lineatum Schumach. is also susceptible to a few pests, the most common being aphids and grasshoppers.
Aphids are small, soft-bodied insects that feed on the plant's sap and can cause stunted growth, curled leaves, and yellow spots. The best way to manage aphids is to wash them off with a strong stream of water, apply insecticidal soap, or release natural predators such as ladybugs.
Grasshoppers can also damage Panicum lineatum Schumach. by feeding on the leaves and stems. To manage grasshoppers, remove weeds and debris from around the plant, apply neem oil or insecticidal soap, and use physical barriers such as mesh netting to prevent them from reaching the plant.
It is important to note that maintaining healthy soil and providing proper cultural practices such as adequate water and nutrition can help prevent diseases and pests and ensure the overall health and vitality of Panicum lineatum Schumach.
