Abstract

An optimized seed pattern with even distances increases the utilizable space of individual plants and reduces intraspecific competition. In addition to higher and more stable yields, benefits in terms of resource use efficiency, stress tolerance and weed suppression are expected. Currently, cereals are mainly sown in rows, which does not corres­pond to the crops’ optimum, but allows a fast sowing. Alternatively, precision seeding is available for cereals, which already allows a more uniform seed pattern.

The most even spacing per single plant can be achieved with a uniform seed pattern in a triangular lattice, which is technically not yet feasible in cereals. In order to test the expected benefits of a uniform seed pattern in cereals, field trials are conducted at the JKI with winter wheat to answer questions regarding yield, resource use efficiency and stress tolerance. At the same time, the adaptation of a precision seeding and the development of an autonomous sowing system are planned in order to enable a uniform seed pattern.
