For 20 consecutive years, the maize cultivar LG 11 has been serving as reference variety at the Federal Research Station for Animal Production (RAP). The collected data and observations provided an appropriate basis to investigate the influence of weather conditions on growth and development of this variety.<br>The Temperature sum (basis 6°C) for the time interval sowing to silking proved to be very constant, the coefficient of variation attaining 4.8 %. The heat sum is also well suited to elucidate the evolution of maize maturation. Our observations confirm the close relationship between the cumulated temperatures (heat sum) and the dry matter content of the ear and whole plant, respectively.<br>Growth conditions affect the energy value of silage maize. It is an established fact that unfavourable weather conditions occurring between silking and harvest, such as drought, unusual temperatures and heavy frost, result in a decrease in the digestibility of organic matter dOM). According to our data, yearly differences in the dOM of the whole plant reach several unity points. The effect of the underlying weather stress on the ear is minor compared to the impaired digestibility of vegetative plant parts (stem and leaves).
Tuta absoluta is one of the most destructive pests of solanaceous crops. Agroscope has developed a statistical model to study the population dynamics of the pest and its parasitoids and allows interventions to be optimally planned.
Swiss vineyards are often small and arranged in a mosaic of separate plots and management practices. Therefore, it can be assumed that spray drift from conventional to organic vineyards occurs regularly. Nevertheless, no pesticide residues are detected in most organic wines.

Red clover is one of the most important legumes in European forage production. In a multi-year field trial, researchers tested Europe’s largest collection of different red clover accessions at five European locations.
