| dc.description.abstract | The aim of the study is to determine the yields in grassland using various methods. Yield recording in grassland has not been common practice so far. Yields can be recorded using various methods as height measurement, for example by using a rising-plate-meter (Grasshopper), measuring the weight of sample cut or by capturing the weight of harvested biomass. A yield estimation with the Grasshopper is carried out on three plots and is validated via sample cuts. The harvest chain is recorded digitally and the harvest quantity (weight) is measured with the load cells in the loader wagon, a validation is carried out via a wagon scales. The results presents underestimated yields when using the Grasshopper. The recording of harvest weights via the loader wagon's load cells was confirmed by the wagon scales. This method can be easily used in practice, if available. However, a determination of the dry matter content remains key. The correct determination of dry matter is crucial for accurate yield recording, but this is where very great challenges lie, especially for practice. Further investigations have to be carried out. | en |
