Agricultural scientists are researching how the performance of cultivated barley can be increased. A drone is now also being used on the experimental station site in Halle.

And how is subsequent analysis then presented? The data generated during the flyover is transferred to a computer. There, the images are rectified by software and broken down into segments. Photogrammetry is the associated method of remote sensing with which the spatial position or a three-dimensional form can be determined from photographs.

The planting density can therefore be determined just as precisely as the number of ears per grid square. This, in turn, can be used to derive state-ments about yield. “This was much more difficult with the previous methods,” explains Klaus Pillen.

But it is not only the innovative use of drones that makes the Halle plant researchers’ project so special. Its complexity is also striking: for one, according to Klaus Pillen, it is of course a matter of practical applicability, i.e. opening up new varieties for cultivation. However, the researchers also hope to understand and clarify the function of certain genes. “This is how we can increase the biodiversity of cultivated barley.”
