Hybrids: 200-300 grains/m2
Population rye: 300-400 grains/m2
Rye is very resistant to cold temperatures.
Rye has a strong root system.
Adjust the nitrogen supply to demand in order to avoid lodging.
Hybrid and population rye require different fertilization.
Seeding is carried out from the end of September to the beginning of October. The planting density varies greatly between varieties. In very good conditions and early sowing with hybrid varieties (70-75% share), very low densities of 150 to 180 seeds/ m2 are possible. Population rye is sown at a density of 250 to 300 seeds/ m2 and late varieties at a density of 300 to 350 seeds/ m2.
Although rye is a relatively robust cereal, it needs plant protection treatment to achieve high yields. The stem and bulb eelworm (Ditylenchus dipsaci) is a pathogenic nematode that also affects rye and is prevalent following a mild winter. Appropriate crop rotation and seed dressing can reduce the occurrence of phytopathogenic fungi (ergot, Claviceps purpurea) which has to be controlled by fungicides.
Due to the early development and high amount of tillering, rye competed well against weeds. A treatment with herbicides should be carried out in autumn.
