Serradella Igela

Information

Seradela (Ornithopus sativus Brot.) belongs to the group of legume, spring, annual plants . The length of its growing period is about 160 days. It tolerates ground frosts down to –5°C. The seradela is grown in the main crop for seed collection or for catch crops in the form of undersown crop or stubble catch crop. It has a high nutritional value of green fodder and hay because it is rich in protein, fat, calcium and potassium. Seradella is a honey plant.

Seradela needs a slightly acidic soil. The pH tolerance ranges from 5.4 to 6.5. Due to the possibility of taking nitrogen from the atmosphere with the use of bacteria, it leaves about 50 kg of N/ha. in the soil

Igela variety

Plants of this variety have a semi-standing type of growth and produce a large amount of side branching. The variety is medium tall. It produces many light green, elliptical leaves. The flowers are pink in colour. The pods are long and wide. The flowering period is medium to late and the maturation period is medium. The length of the growing season is approximately 135 days. It has a high yielding potential of seeds, from 0.8 to 1.5 tons/ha. It is characterised by a stable seed yield and is suitable for organic farming . It is an extremely valuable cover crop: undersown crop, stubble cover crop. It is possible to use it to create aftercrop mixtures, e.g. with oats. It also brings beekeeping benefits.

Siew	Seradelę na nasiona wysiewa się w 3–4 roku po oborniku, w ilości 20–30 kg/ha, w rzędach co 12,5–15 cm pod koniec marca lub na początku kwietnia.
Nawożenie	Nawozy fosforowo-potasowe stosuje się przedsiewnie, na wiosnę, w zależności od zasobności gleby: 40–80 kg P₂O₅/ha , 80–120 kg K₂O/ha. Stosowanie nawozów azotowych jest zbędne.
Zbiór dwufazowy	Koszenie na pokosy gdy na dolnej części rośliny większość strąków zaczyna brązowieć (około 50%), a w środkowej żółknąć. Nie należy czekać na zakończenie kwitnienia w górnej części. Koszenie na pokosy trzeba przeprowadzić „po rosie” czyli wieczorem lub wcześnie rano, co zapobiega osypywaniu nasion. Wyschnięte pokosy należy omłócić kombajnem.
Zbiór jednofazowy	Polega na desykacji plantacji (suszenie chemiczne) i omłocie kombajnem z pnia. Uzyskany materiał należy dosuszyć do wilgotności 14% i wyczyścić. Plon seradeli wahają się od 0,6 do 1,0 t/ha.

Sowing	Serradella for seeds is sown 3-4 years after the manure, at the rate of 20-30 kg / ha, in rows every 12.5-15 cm at the end of March or the beginning of April.
Fertilization	Phosphorus-potassium fertilizers are used before sowing, in the spring, depending on the soil fertility: 40-80 kg P₂O₅/ha, 80–120 kg K₂O/ha. The use of nitrogen fertilizers is unnecessary.
Two-phase set	Mowing for swaths when most of the pods turn brown in the lower part of the plant (about 50%), and turn yellow in the middle part. Do not wait for flowering in the upper part to finish. Mowing for swaths must be carried out “after dew”, that is in the evening or early in the morning, which prevents the seeds from shedding. Dried swaths should be threshing with the combine.
Single-phase harvesting	It consists in desiccating the plantation (chemical drying) and threshing from the trunk with a combine. The obtained material should be dried to a humidity of 14% and cleaned. The yield of serradella varies from 0.6 to 1.0 t / ha.
