Zulla, scientifically known as *Hedysarum coronarium*, is a perennial forage plant that has gained popularity among farmers and ranchers due to its ability to provide essential nutrients to the soil and its high nutritional value for livestock. In this article, we will explore its characteristics, benefits, and tips for successful cultivation.
Characteristics of Zulla
Zulla is a legume native to the Mediterranean region, but it adapts to various climatic conditions. Some of its most notable characteristics include:
- – Deep Root System: Its deep roots allow it to access mineral nutrients and water, making it resistant to drought conditions.
- – High Protein Content*: Zulla leaves are rich in protein, making it an excellent fodder for livestock.
- – Soil Improver: Being a legume, it has the ability to fix atmospheric nitrogen, thus improving the fertility of the soil in which it is grown.
Benefits of Zulla Cultivation
- 1. Increased Natural Fertilization: Zulla contributes to the improvement of soil quality by fixing nitrogen, which reduces the need for chemical fertilizers.
- 2. High Quality Forage: Its high energy and protein content makes it an ideal forage for feeding livestock, promoting healthy growth and greater milk and meat production.
- 3. Sustainability: Growing zulla can be part of a sustainable agriculture strategy, helping to maintain biodiversity and the health of the local ecosystem.
- 4. Resistance to Pests and Diseases: Due to its natural adaptation to diverse conditions, zulla has greater resistance to pests and diseases compared to other forage crops.
Growing Requirements
To obtain the best results when growing zulla, it is important to take into account the following factors:
1. Suelo
Zulla prefers well-drained soils rich in organic matter. A slightly acidic to neutral pH (6.0-7.0) is optimal. It is advisable to perform a soil analysis before planting to determine the suitability of the conditions.
2. Climate
This legume grows best in temperate Mediterranean climates. However, it can tolerate higher temperatures and dry soils, making it an excellent choice for regions with warmer climates.
3. Sowing
Sowing can be done in late winter or early spring. A sowing density of approximately 15-20 kg per hectare is recommended. Seeds should be sown at a depth of 2-3 cm.
4. Irrigation
An adequate supply of water is essential during the early stages of growth. However, once established, the plant is drought-resistant.
5. Harvest
Zulla can be harvested several times a year. It is vital to avoid overgrazing, allowing the plant to recover and maintaining its forage capacity.
The cultivation of zulla (Hedysarum coronarium) not only offers economic and nutritional benefits for livestock, but also helps in the sustainability of the soil and the ecosystem. By adopting proper cultivation practices, farmers can maximize the benefits of this versatile and nutritious plant, contributing to the well-being of their farms and the environment. If you are considering diversifying your forage production, zulla could be an excellent option to consider.
6. Uses
As a forage crop and/or for hay or silage production: A single cut for hay or silage can be made in the first year of cultivation in spring. In the second year of cultivation, a single cut or two can also be chosen. If a single cut is chosen, this would be in spring and if two cuts are made, one would be in early spring and the other in May-June, depending on the location. The supply of forage on the market, the main factor in prices, will be the criterion for choosing between one or two cuts.
As a pasture crop: To make the most of the nutritional wealth of zulla, it should be used when the plant reaches a height of approximately 30-40 cm, and should not be grazed below 10 cm as this would delay regrowth.
As green manure in the second year of cultivation due to its high production of dry matter.
As a nitrogen fixer in mixed cropping systems.
