How Digitised are Swiss Plant Production Farms?

Digital technologies are fixed features of modern agriculture – but to what extent are they already being used in Switzerland? A survey conducted by Agroscope provides answers to this question. Digital technologies reduce the physical workload of farming and contribute to sustainable field management. They also enable optimised management decisions based on plant- or soil-related…

A closer look at red clover: results of the 2016–2018 variety testing

From 2016 to 2018 inclusive, Agroscope tested 54 varieties of red clover (Trifolium pratense L.) at six locations. Of these, 25 were new varieties and 29 were already-recommended varieties that were being retested. Yield, vigour, juvenile development, resistance to leaf diseases and anthracnose, winter-hardiness and persistence were all evaluated. For the persistent “mattenklee” type, the…

Genetic diversity of Trichopria drosophilae, a natural enemy of spotted wing drosophila

Drosophila suzukii is an invasive species recently introduced in Europe and causing damages to fruit production. Trichopria drosophilae is considered one of the most suitable indigenous parasitoid to be used in biocontrol programs against D. suzukii. To characterize genetic variability and the spatial genetic structure of populations of T. drosophilae, we developed 21 species-specific molecular…

Protecting resources with agroforestry systems: regionally adapted solutions

The Swiss Federal Government’s agricultural policy aims inter alia to provide agricultural ecosystem services, reduce environmental impacts, and increase the resilience of the agricultural sector. Combining the cultivation of trees with crops or grass – termed «agroforestry » – can contribute to achieving these goals without substantially limiting agricultural production. We identified the regions where…

Trials with meadow fescue: two new varieties recommended

From 2016 to 2018, Agroscope tested a total of 23 varieties of meadow fescue, including 16 new varieties, in comparative variety trials at six locations. The varieties were assessed on the basis of systematic examinations and observations of forage yield, vigour, juvenile development, competitive ability, persistence, tolerance to winter influences, resistance to leaf diseases, digestibility…

Growing buckwheat in Switzerland: new varieties for an old niche crop

Interest in buckwheat production has been growing for several years now in Switzerland. Previously, this field crop had almost completely been forgotten. Since it is not related to other arable crops, buckwheat is ideal for breaking up crop rotations. It is also interesting from a nutritional point of view, as it contains zinc and selenium,…

The growth of companion cropping in oilseed rape: feedback on the opinions of Swiss producers

The practice of sowing companion crops (or «service plants») in among oilseed rape began to get off the ground in Switzerland several years ago. Certain farmers see companion cropping as an innovative technique allowing them to cut back on the use of plant-protection products, and in particular enabling them to forgo the use of herbicides,…

New challenges to digitization of genetic resources for food and agriculture

A comprehensive stewardship of genetic resources is necessary to insure a resilient and sustainable agriculture. Most of our food comes from a handful of domesticated species which diversity is constantly shrinking. On the contrary, modern genomics keep discovering the marvels of diversity contained in genetic resources for food and agriculture. High-throughput sequencing and related techniques…

Preserving the sustainability of field crop systems: overview of 50 years of trials in Changins

Preserving soil fertility is a major challenge for farms without livestock specialised in field crops. Several decades ago, several trials were set up at the Agroscope experimental station in Changins to study the long-term effects of different cultural practices on soil fertility and crop yields. This article summarises the main results obtained in these trials.…

2015–2017 variety trials with xFestulolium braunii and brome grass

Between 2015 and 2017, Agroscope tested seven new varieties of xFestulolium braunii (K. Richter) A. Camus and four varieties of brome grass (Bromus spp.) for their agronomic properties in comparative trials at six locations. The characteristics studied were yield, juvenile development, general impression, competitive ability, persistence, resistance to leaf diseases and bacterial wilt, winter hardiness,…

New cocksfoot variety recommendation: «RGT Lovely» instead of «Lazuly»

From 2015 to 2017, a total of 23 varieties of cocksfoot (Dactylis glomerata L.), 11 of which were new varieties, were tested on seven Agroscope sites as to their suitability for use under Swiss growing conditions. The varieties were evaluated according to yield, feed digestibility, vigour, juvenile development, competitive ability, resistance to leaf diseases, winter-hardiness…

Phosphorus and potassium requirements of a hay meadow of the Swiss Jura dominated by red fescue

Phosphorus (P) and potassium (K) inputs on grassland aim to maintain an appropriate botanical composition and to produce sufficient quantities of forage without harming the environment. Over a 13-year period, eight different levels of P and K fertilisation were applied on a low-intensive permanent grassland in the Swiss Jura. Rising inputs of P (between 0…

Simulation of grass growth and pasture yields with ModVege

Predicting grass growth could be very useful for the management of pastures, or deciding the best time to harvest hay meadows. The ModVege model was tested and improved using a set of 125 situations (meadow × year × management) collected from grassland areas in Switzerland. Comparisons between simulated and measured data show relatively reliable outputs…
