Fertilization

In principle, rye out of all cereal species has the best ability to acquire nutrients based on its well-developed root system. In crop rotation rye is basically used as the last crop, which enhances its demand for an adequate fertilisation regime.

Depending on the location’s expected yield, the scheduled value for rye (incl. Nmin) should be between 140 to 160 kg N/ha. As a rule of thumb for hybrid rye, 2 kg N/ha (incl. Nmin and N-additional application) per 100 kg/ha of yield are applied.

In practice, nitrogen systems working with stabilised N-fertilisers applied in one split show advantages over conventional N-strategies on dry locations.

The yield reliability of rye has to be primarily secured with basic nutrients. Rye is mainly grown on poor soils, where water stress can often occur during the vegetation period. On such locations it is important to secure the potassium supply enhancing the nitrogen and water use efficiency as well as the stress tolerance of plants.
