The bachelor thesis deals with an agricultural suspension device for cultivation and fertilization of an alternate row of broad-leaved plants such as corn, sunflower, beets and rape. Another goal was to analyse currently used technologies, where I compared four existing manufacturers and evaluated the positives and negatives of these devices. By researching the market, I have found that there is a large number of such devices in agricultural practice, but they are not suitable enough for use in higher growth stages, when the plant reaches its height of 1.1 - 1.2 m. As a result of technical marketing, I propose a concept for a new facility that can make a significant contribution to agricultural practice by being engineered to be able to process plants when they need to get the most nutrients to grow. Another advantage of this device can be its versatility in the selection of a suspension device, where it is possible to connect this device not only to the tractor but also to the self-propelled sprayer.
