The use of the necessary resources is particularly important in order to be able to be economically successful in addition to good returns. This requires very special control of the grain stock, on the one hand by the seed rate, but also by the time of sowing. Both parameters can have a corresponding influence on the yield and quality of the harvested product.

If, on the one hand, a reduction in seed starch leads to a higher protein content, this is important for marketing as a consumer grain, but can lead to a higher density of weeds or grasses within the grain field. The operator therefore has to make the difficult decision as to which seed strength to use for which type of grain. With feed grain, the problem of weed infestation can be solved more easily by narrowing the row width than with consumer goods, which must have a minimum protein content in order to achieve an economical price. Various projects have already been carried out in this area by different institutions, all of which aim to increase the protein content of wheat while reducing the seed rate. Here the problem with the increased weed infestation was usually solved by the so-called 'wide row' using mechanical cultivation and/or under-sowing. There are already clear results with a significant increase in the protein content of wheat. However, the climatic conditions at the different locations for this scientific activity differ greatly from one another, which is why it can be assumed that with increasing amounts of precipitation, the problem of weeds and grasses will become more prominent.
The time of sowing is of great importance, especially with regard to susceptibility to disease, which can have a particularly negative impact on quality.
As part of this scientific activity, experiments with grain will be carried out at various locations, in which both the seed rate and the time of cultivation vary. In these experiments, which only include a small number of objects, both yield data and quality are to be recorded, as well as all observation data with regard to plant diseases or pest infestation.
