In Spain, it is known as Esparraguera, while in Italy, it is called Erba Trifoglietta and Trèfle des sables in French-speaking countries.
Uses
The plant Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál is used for pasture, hay, and silage production because it is highly palatable to both livestock and wildlife. It is also used as a green manure crop to improve soil fertility and suppress weeds. Additionally, its seeds can be used for human consumption, as they are high in protein and can be made into a nutritious flour.
General Appearance
Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál is a small, herbaceous plant that typically grows up to 50 cm in height. It has a slender stem with small leaves that form a trifoliate pattern. The plant produces small, pink or white flowers that bloom in the summer. The fruit is a small, cylindrical pod that splits into two parts when it is ripe, releasing multiple small seeds.
Light Requirements
Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál requires full sun exposure to grow. This means that the plant requires at least six hours of direct sunlight every day to thrive. Lack of adequate sunlight may lead to poor growth or even total plant failure.
Temperature Requirements
The plant is best suited to grow in warm to hot temperatures. Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál grows best between 20 and 30 degrees Celsius. The plant will not grow well in cold temperatures, and it may die if exposed to frost during the growing season.
Soil Requirements
The plant prefers well-drained soil. Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál requires a slightly acidic to neutral soil with a pH between 6.0 and 7.5. The plant will not grow well in waterlogged or heavy clay soils. The soil should be amended with organic matter to improve its fertility and drainage.
Cultivation Methods
Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál is an annual herb that grows up to 50cm in height and can tolerate a wide range of soil types, including those that are saline or alkaline. It is primarily grown as a forage crop and is cultivated in open fields with good sunlight exposure. The crop can be sown either through broadcast or drill methods. Broadcasting involves scattering the seeds evenly on the surface of the soil and covering them with a thin layer of soil. On the other hand, drilling involves making small holes in the soil and planting the seeds inside them. The latter method is preferred as it results in better seedling establishment and a higher yield.Watering Needs
Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál requires moderate watering, and the soil should be kept consistently moist during the germination period. However, too much water can lead to root rot and fungal infections. It is advisable to water the plants in the early morning or late evening to minimize water loss due to evaporation.Fertilization
The plant requires a moderate amount of nitrogen for optimal growth. If the soil lacks nitrogen, it can be supplemented using nitrogen-rich fertilizers or by incorporating organic matter such as manure or compost into the soil. It is recommended to avoid using excessive fertilizers as this can lead to reduced seed yield and poor plant quality.Pruning
Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál does not require pruning as it is primarily grown as a forage crop. However, the plant can be cut back to the ground after harvesting to promote regrowth and improve the quality of subsequent harvests. It is essential to ensure that the soil is well-drained before cutting back the plant to prevent the roots from rotting.Propagation of Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál
Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál, commonly known as the serradella or Spanish clover, is a legume crop commonly grown for forage in Mediterranean regions. Propagation of Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál can be done through several methods such as using seeds, vegetative propagation, stem cuttings, or grafting.
Seed Propagation
Seed propagation is the most common and easiest method for propagating Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál. The seeds can be directly sown in the field after the last frost or at the beginning of the rainy season. The seeds should not be sown too deep in the soil. The ideal depth is around 2-3 cm. The seeds will germinate in about 7 to 10 days in good soil conditions. Once the seedlings are 4 to 6 inches tall, they can be thinned out, keeping only the strongest ones for proper growth.
Vegetative Propagation
Vegetative propagation of Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál can be done by using root cuttings, tubers, and rhizomes. This method is more common in research labs as it requires specific and controlled conditions to achieve successful sprouting. The vegetative propagation method is not commonly used in commercial production because of its low success rate and effort.
Stem Cuttings
Stem cutting is another method of propagation for Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál. In this method, the stems are cut into small pieces, which are then planted in a prepared soil bed. This method is often used in greenhouses as it requires controlled environmental conditions for better growth. It is crucial to keep the soil moist for proper sprouting. However, the success rate of this method is variable and lower than that of seed propagation.
Grafting
Grafting is a less common method of propagation for Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál. It is used less often because the plant is already a desirable cultivar. However, grafting can be used for enhancing plant growth and resistance to diseases. In grafting, a scion of the desired cultivar is attached to a rootstock of a different cultivar, which supports the growth of the new plant. However, grafting requires specific knowledge and skills to achieve success.
Disease Management
Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál is prone to several diseases that can cause significant damage to the plant. Some of the most common diseases that affect this plant include:
- Fusarium wilt: This is a fungal disease that causes wilting and yellowing of the leaves. It can also cause stunting of the plant and root rot. To manage the disease, it is essential to practice crop rotation, remove and destroy any infected plant materials and use certified disease-free seeds.
- Root rot: This is also a fungal disease that affects the roots of the plant. It causes stunted growth, wilting, and yellowing of the leaves. To manage the disease, avoid over-watering and waterlogging the soil. Using well-drained soil and practicing crop rotation can also help prevent root rot.
- Powdery mildew: This is a fungal disease that affects the leaves of the plant. It causes a white powdery substance to appear on the leaves, and they eventually turn yellow and fall off. To manage powdery mildew, it is essential to maintain good air circulation and avoid overcrowding the plants. Applying fungicides can also help control the spread of the disease.
Pest Management
Ornithopus sativus Brot. ssp. isthmocarpus (Coss.) Dostál can also be affected by several pests that can cause significant damage to the plant. Some of the most common pests that affect this plant include:
- Aphids: These pests suck the sap from the leaves of the plant and can cause stunted growth and yellowing of the leaves. To manage aphids, it is essential to use insecticidal soaps or neem oil to control their spread.
- Root-knot nematodes: These pests feed on the roots of the plant, and their presence can cause stunted growth and yellowing of the leaves. To manage root-knot nematodes, it is essential to practice crop rotation and use nematode-resistant varieties of the plant.
- Two-spotted spider mites: These pests feed on the leaves of the plant and can cause a yellowing and bronzing of the foliage. To manage spider mites, it is essential to maintain good air circulation and avoid overcrowding the plants. Using insecticidal soaps can also help control the spread of the pest.
