Eragrostis Tef (zuccagni) Trotter - Teff

Eragrostis tef (Zuccagni) Trotter: An Overview

Eragrostis tef, also known as tef, is a species of lovegrass that is primarily cultivated for its tiny seeds, which are a staple food in Ethiopia and Eritrea. It is a member of the Poaceae family and is believed to have originated in Ethiopia around 5000 years ago.

Common Names

In addition to tef, Eragrostis tef is known by several other common names, including lovegrass, teff, Williams' lovegrass, annual bunch grass, and Abyssinian lovegrass.

Appearance

Eragrostis tef is an annual grass that typically grows to a height of 1-2 feet. It has a narrow, upright growth habit and produces many slender stems. The leaves are long and narrow, and the seedheads are composed of tiny, round seeds that are about the size of a poppy seed. The seeds come in a variety of colors, including white, red, brown, and black.

Uses

Eragrostis tef is primarily cultivated for its seeds, which are ground into flour to make traditional Ethiopian and Eritrean foods such as injera, a spongy, fermented bread. The flour is also used to make porridge, pancakes, and other dishes. In addition to its use as a food crop, Eragrostis tef is also used as a forage crop for livestock and as a cover crop to prevent soil erosion.

Light Requirements

Eragrostis tef thrives in full sun to partial shade. It requires at least six hours of direct sunlight per day to grow optimally. If grown in partial shade, it should be in an area that receives bright, filtered light for most of the day.

Temperature Requirements

Eragrostis tef is a tropical plant that thrives in warm temperatures between 60-85°F. The plant is sensitive to frost and will not survive in areas with freezing temperatures. The best growth occurs when the temperature is around 77°F during the day and 68°F at night.

Soil Requirements

Eragrostis tef prefers well-draining, sandy loam soils with a pH between 6.0-8.5. The plant is tolerant to drought, but it needs regular watering to maintain growth and yield. Soil fertility is also essential for optimal growth. Adding organic matter or a balanced fertilizer can significantly improve soil fertility, leading to healthy plant growth.

Cultivation of Eragrostis tef

Eragrostis tef is a warm-season plant that thrives well in the tropical and subtropical regions. It can grow in various soil types like sandy, loamy, or clay soil that is well-drained.

The best planting time for Eragrostis tef is during the rainy season or the onset of the rainy season. The seeds should be planted in rows and covered with soil that is not more than 1 cm deep. Plant spacing should be between 20cm to 25cm.

It is crucial to keep the area weed-free by regular hoeing or tilling around the plants. When the seeds start to germinate, you can gradually thin the plants by uprooting the weak ones until the final spacing is about 10cm to 15cm apart.

Watering Needs

Eragrostis tef requires adequate moisture for proper growth and production. The plant can tolerate dry soil conditions, but its yields will be significantly reduced. Ensure that the plant receives about 300mm to 400mm of rainfall each season or alternatively, irrigation should be provided when necessary.

Fertilization

Eragrostis tef requires a balanced application of nitrogen, phosphorus, and potassium. This plant is a heavy feeder, so it requires regular application of nitrogen to maintain its growth and plump seeds.

Organic fertilizers like compost and manure can be added to the soil before planting to provide adequate nutrients. You can also supplement with inorganic fertilizers like urea, calcium ammonium nitrate, and triple superphosphate.

It is recommended to perform a soil test to determine the nutrient and pH levels of the soil before applying fertilizers.

Pruning

Pruning is not necessary for Eragrostis tef plants, but it is essential to remove the seed heads before they start to fall off to avoid seed loss.

Harvesting of Eragrostis tef should occur when the seedheads have turned beige and dry. The seeds can be harvested by cutting off the seedhead and threshing them to separate the seeds from the plant.

It is also essential to collect and store seeds correctly to ensure they remain viable for the next planting season.

Propagation of Eragrostis tef

Eragrostis tef, also known as teff, is an annual grass species that is primarily cultivated for its tiny grain, which is a staple food crop in Ethiopia and Eritrea. The plant is also grown for forage and as a cover crop in other parts of the world. Here are some of the common methods of propagating Eragrostis tef:

Seed propagation

The most common method of propagating Eragrostis tef is through seeds. The seeds are very small, and it takes a large number of them to establish a new crop. They are typically sown directly into the soil, either by broadcasting or by drilling. The seedbed should be well-prepared and moist, with a fine tilth to ensure good seed-soil contact. It is important to sow the seeds evenly and at the right depth (1-2 cm).

Vegetative propagation

Eragrostis tef can also be propagated vegetatively, although this is less common. This is typically done by taking stem cuttings, root cuttings, or tillers from existing plants and planting them in a new location. This method can be faster than seed propagation and can be useful for maintaining specific genetic characteristics or for propagating diseased-free plants.

Cultural practices for propagation

In addition to the above methods, there are several cultural practices that can promote the successful propagation of Eragrostis tef. For instance, the plant prefers warm temperatures and high humidity, so it is important to plant it during the right season and to keep the soil moist. It is also important to control weeds, which can compete with the young plants for water and nutrients. Finally, fertilization can be helpful, especially if the soil is deficient in certain nutrients.

Disease Management

Eragrostis tef can be susceptible to several diseases that can impact the yield and quality of the crop. Some of the common diseases that affect the plant include:

• Bacterial leaf spot: This disease causes small water-soaked lesions on the leaves, which later turn into brownish-black spots. The spots can coalesce, leading to the death of the leaf. Copper-based fungicides can be used to manage the disease.
• Fusarium wilt: The disease affects the roots, causing yellowing, wilting, and death of the plant. Crop rotation and soil fumigation with methyl bromide can help to control the disease.
• Anthracnose: This disease causes circular, tan-colored lesions on the leaves and stems, which can later turn into elongated black streaks. The use of copper-based fungicides and rotation with non-host crops can help to manage the disease.

In addition to these diseases, Eragrostis tef can also be affected by fungal diseases such as powdery mildew and smut. Good cultural practices, such as proper sanitation, crop rotation, and the use of disease-resistant varieties, can help to prevent these diseases from affecting the crop.

Pest Management

Eragrostis tef can be affected by several pests that can cause significant damage to the crop. Some of the common pests that affect the plant include:

• Aphids: These are small, soft-bodied insects that feed on the sap of the plant, causing stunted growth and deformities. Insecticidal soap and neem oil can be used to manage the pest.
• Cutworms: These are larvae of several species of moths that cut off the plant's stem at or below ground level. The use of biological control agents, such as Bacillus thuringiensis (Bt), can help to control the pest.
• Grasshoppers: These are herbivorous insects that can cause significant damage to the leaves and stems of the plant. Insecticidal sprays can be used to manage the pest.

The use of proper cultural practices, such as timely planting and irrigation, can also help to prevent pest infestations. Additionally, the use of pest-resistant varieties can reduce the impact of pests on the crop.
