The cereal crop yields vary from year to year, mainly as a result of the weather during the growth period. Nevertheless, a trend towards ever-higher yields is observed over time. This has to do with biotechnological advances. The aim of this paper was to analyse the cereal crop yields and to determine the size of the annual increase in the case of wheat, barley and triticale crops. The average increase in yield was calculated with a linear regression, using information on the input factors, weather, location and type of farming. Tests showed that the average increase in yield per hectare and year was around 50 kg for wheat and barley, and around 150 kg for triticale.
Herbicide-resistant weeds are a growing problem throughout the world. Monitoring herbicide resistance in Switzerland allows us to understand the mechanisms behind it and to better manage the use of herbicides.
Agroscope compared crop protection strategies in apple production. Reducing the use of plant-protection products lowered the local ecotoxological risks, but resulted in trade-offs between environmental and economic performance.
Bacillus thuringiensis (Bt) bacterium proteins protect Bt maize from being fed on by specific insects. A new, systematic analysis of international field data confirms that non-target organisms in Bt maize are largely spared.
