Pruning of Onobrychis viciaefolia Scop.
Sainfoin plant does not require pruning as it is a low-growing plant. However, if the plant grows too tall, it can be mowed back to 10 to 15 cm above the ground to encourage new growth. The plant should also be cut or grazed before flowering to ensure maximum forage quality. After flowering, the plant produces hard and unpalatable stems, reducing its forage value.
Propagation of Onobrychis viciaefolia Scop.
Onobrychis viciaefolia Scop. or common sainfoin is a forage crop that is native to Europe and Asia. It is a hardy perennial that is well adapted to various types of soils. The plant is usually propagated by seed, but it can also be propagated through vegetative means.
Seed propagation
The most common method of propagating Onobrychis viciaefolia Scop. is through seeds. The seeds can be sown directly in the field in the early spring or fall. The soil must be well-prepared, free from weeds, and well-drained. The seeds should be sown at a depth of about 1-2 cm and should be spaced about 10-15 cm apart. The soil must be kept moist until the seeds germinate.
The seeds of Onobrychis viciaefolia Scop. have a hard seed coat that needs to be scarified before sowing to enhance germination. The seeds can be scarified by soaking them in hot water for about 5-10 minutes, or by rubbing them with sandpaper.
Vegetative propagation
Onobrychis viciaefolia Scop. can also be propagated through vegetative means such as cuttings and division. Cuttings are taken from the new growth of the plant and rooted in a well-drained soil. The cuttings should be about 5-7 cm long and should be placed in a rooting hormone before planting. The soil must be kept moist until the cuttings root.
Division is another method of propagating Onobrychis viciaefolia Scop. This method involves dividing the established plant into smaller sections that can be replanted. The best time to divide the plant is in the early spring before new growth appears. The plant should be lifted from the ground and the roots should be carefully separated into smaller sections. The sections can then be replanted in a well-prepared soil that is kept moist until new growth appears.
Overall, Onobrychis viciaefolia Scop. is a hardy plant that is easy to propagate. Whether through seed or vegetative means, this plant can be an excellent addition to any forage crop.
