Cultivation of Dichanthium tenue (R. Br.) A. Camus
Dichanthium tenue (R. Br.) A. Camus is a hardy grass plant that grows well in warm climates. It requires minimal care and attention and can thrive even in low nutrient soils.
The best time to plant Dichanthium tenue is in the summer months when the soil is warm and moist. The seeds should be planted at a depth of 1 cm and spaced 20 to 30 cm apart. Once planted, the seeds should be watered regularly to keep the soil moist until the grass starts to grow.
Watering Needs
Although Dichanthium tenue is a hardy plant, it still needs regular watering to thrive. The plant can tolerate drought conditions, but it will grow better with regular watering. The best time to water is early in the morning or late in the evening.
The amount of water required by the plant will depend on the climate and soil conditions. In general, the plant needs about 2.5 cm of water per week. To avoid overwatering, make sure the soil has good drainage and allow it to dry out between waterings.
Fertilization
Dichanthium tenue is a low nutrient plant and does not require fertilization. However, if you want to encourage faster growth or improve the quality of the grass, you can add a slow-release fertilizer during the growing season. You should avoid using high-nitrogen fertilizers, as they can cause the grass to grow too quickly and become susceptible to disease.
Pruning
Dichanthium tenue is a low maintenance plant and does not require pruning. However, to keep the grass looking neat and tidy, you can mow it to a height of 5 to 10 cm. This will also help to stimulate new growth and thicken the turf.
Propagation of Dichanthium tenue
Dichanthium tenue (R. Br.) A. Camus, also known as slender pigeon grass, is a warm-season grass that is native to Africa, Asia, and Australia. It is commonly grown as a forage crop for livestock, as well as for soil conservation and erosion control. Propagation of Dichanthium tenue can be done through various methods, such as seeds, vegetative propagation, and tissue culture.
Propagation by Seeds
Propagation of Dichanthium tenue through seeds is the most common method used. Fresh seeds have a higher germination rate compared to old seeds. The seeds should be sown during the summer season in warm, moist soil. The soil temperature should be maintained at around 25°C to ensure successful germination. The seeds should be sown at a depth of about 1-2 cm and spaced around 15-20 cm apart. Upon germination, the seedlings should be thinned to maintain a plant stand of around 7-10 plants per square meter.
Vegetative Propagation
Vegetative propagation of Dichanthium tenue can be done through stem cuttings or sod planting. Stem cuttings can be obtained from mature plants during the dry season. The cuttings should be around 15-20 cm long and should be planted in well-prepared soil. The soil should be kept moist until the cuttings develop roots. Sod planting involves the transfer of mature plant sections to another location. The sods should be dug out carefully and should be planted immediately in the desired location. Adequate moisture should be provided to facilitate root development.
Tissue Culture Propagation
Tissue culture propagation of Dichanthium tenue is a relatively new method that involves the use of plant tissue samples to generate new plants. The tissue samples are obtained from mature plants and are placed in an artificial nutrient culture medium. The samples are then treated with growth hormones to stimulate cell division and plant development. The resulting plantlets are then transferred to soil for further growth and development. Tissue culture propagation is a useful method for producing large quantities of uniform plantlets with desirable characteristics.
