Camelina planting

The small size of the seed, with a GMP ranging from 0.7 to 1.8 g, represents a challenge for successful planting. Soil cultivation and sowing methods must provide a seedbed conducive to good contact between seed and soil, while limiting the impact of residues from the previous crop.

The success of camelina in summer intercropping depends largely on its rapid establishment. This crucial stage requires rapid, uniform and vigorous emergence. Everything must be done to ensure that the cycle is completed as quickly as possible, so that harvesting can take place at an acceptable date, maximizing the chances of harvesting camelina under favorable climatic conditions and having no impact on the following crop.

To maximize the chances of early emergence, it is crucial to choose a suitable crop precedent, enabling harvesting before July 10, the latest date for sowing camelina. The optimum sowing date is before the beginning of July. The most suitable crops are protein or canning peas and winter barley.

Previous pea crop

Sowing should be carried out as soon as possible after harvesting the previous crop, ideally within 24 to 48 hours, to take advantage of any remaining soil moisture.
Direct sowing with tines is strongly recommended. In the case of shallow stubble ploughing, do not go deeper than 3 cm to maintain soil moisture.

Seeding depth :

• Direct seeding: seed 3 cm deep
• Tilled seeding: seed 1-2 cm deep
• Surface seeding: not recommended

Regarding sowing density, we recommend sowing at 8 kg/ha with a row spacing of 12.5 - 15 cm, to aim for a stand of around 200 plants/m2.

If you have irrigation, we strongly recommend applying 10-20 mm just after sowing to boost emergence.

Previous winter barley

The only difference between winter barley and peas concerns harvesting, which should be carried out as high up as possible (between 25 and 30 cm).

It is important to remove the straw, as it can consume nitrogen as it decomposes, and adversely affect sowing quality by disturbing contact between the seed and the soil.

Straw should also be evenly distributed over the entire surface.

All other recommendations for planting remain identical to those applied to previous peas.

Sowing should be carried out in well-aerated, uncompacted soil. Due to the small size of its seeds, camelina requires particularly careful, fine and well-reconsolidated seedbed preparation. Tillage should aim for a homogeneous profile, with no marked areas of compaction, and a surface area comparable to that required for rapeseed sowing.

For spring camelina, the soil should be worked when it is well drained. To reduce the risk of soil compaction, we recommend reducing the number of tractor passes as much as possible, and favouring the use of combined implements. Rolling prior to sowing can be considered to even out the seedbed and ensure good contact between the seed and the soil, a condition favorable to successful germination.

Sowing takes place between late March and early April, using a cereal drill with a narrow row spacing (12.5 to 15 cm). The recommended sowing density is 5 kg/ha, aiming for a minimum population of 200 plants/m². Sowing depth should be between 1 and 1.5 cm. If required, seeds can be mixed with sand or semolina to facilitate even distribution.
