Cultivation Methods of Camelina rumelica Velen.
Camelina rumelica Velen., commonly known as Bulgarian gold-of-pleasure, is an annual plant from the Brassicaceae family. It is cultivated primarily for its oil-rich seeds, which have numerous industrial applications, including biodiesel production, as well as its use in human and animal nutrition, and medicinal purposes.
The plant grows well in temperate climates and requires a well-draining soil structure with moderate fertility. It can, however, grow well in soils with low fertility levels as long as they are adequately drained. The plant is sown in the spring, and its seeds germinate at temperatures ranging from 4°C to 28°C. The optimal planting rate is around 1-2 kg per hectare, and the sowing can be done either by broadcasting or drilling.
It is important to ensure that the plants are placed at a proper distance of 10-20 cm apart, allowing adequate airflow and reducing the risk of diseases. The planting depth should be between 1-3 cm, depending on the soil type, climate, and seed size.
Watering Needs of Camelina rumelica Velen.
Camelina rumelica Velen. requires a moderate water supply. It can withstand drought-like conditions well due to its deep taproot that seeks water from lower soil layers.
However, rainfall levels between 400-800 mm are ideal for proper growth and seed production. It is recommended to water the plants when there has been no rainfall for more than a week, applying enough water to moisten the soil to a depth of about 30 cm. Overwatering should be avoided as it can promote rotting of the roots and even plant death.
Fertilization of Camelina rumelica Velen.
Camelina rumelica Velen. plants require moderate amounts of nitrogen, phosphorus, and potassium. An application of 40-60 kg/ha of nitrogen and 30-50 kg/ha of phosphorus is essential for optimal growth and seed production. This should be applied evenly across the field, either during planting or before the plant reaches the vegetative stage.
The timing and method of fertilization can be adjusted according to the soil and climatic conditions. Overfertilization should be avoided as it can lead to a reduction in seed quality, environmental pollution, and waste of resources.
Pruning of Camelina rumelica Velen.
Pruning is not a typical practice for Camelina rumelica Velen. Directly from germination, the plant undergoes a rapid vegetative growth phase, followed by flowering and seed setting. After harvesting, the plant is typically left to regrow in the field, thus naturally increasing soil fertility by dropping organic material decomposing in the soil. Otherwise, if plants dry out on top of the soil, you can cut them down with a motorized scythe.
Propagation of Camelina rumelica Velen.
Camelina rumelica Velen. is a herbaceous plant that naturally occurs in various habitats across Europe, including meadows, fields, and roadsides. This plant can be propagated both by seeds and vegetatively, although the former is the most common and efficient method.
Seed propagation
Propagation of Camelina rumelica Velen. by seeds is relatively easy and straightforward. The best time to collect the seeds is in the summer, when the fruit is mature and starts to fall off naturally. The seeds need to be cleaned and dried before sowing, to avoid any potential fungal or bacterial infections.
The seeds should be sown in a well-prepared soil, either in a seedbed or directly in the field, in the autumn. The soil should be moist and well-drained, with a pH between 6 and 7. The recommended depth for the seeds is about 1 cm, and the distance between the rows should be around 20 to 30 cm. The seeds will germinate in about 10 to 14 days, and the plant will reach maturity in about four months.
Vegetative propagation
Vegetative propagation of Camelina rumelica Velen. is less common and more challenging than seed propagation, as this plant does not produce many aboveground offshoots that can be used for propagation. However, the root system is quite extensive, with lateral roots that can sprout new plants.
The most effective way to propagate Camelina rumelica Velen. vegetatively is by taking root cuttings in the autumn, after the plant has withered. The cuttings should be about 5 to 10 cm long, with at least two or three buds, and should be planted in a well-moistened soil. The soil should be kept moist, but not waterlogged, until the cuttings develop new shoots and start to grow on their own.
In conclusion, Camelina rumelica Velen. can be propagated both by seeds and vegetatively, although seed propagation is the most common and efficient method. Successful propagation depends on many factors, such as soil quality, moisture, temperature, and light.
