Preventive effects of different fertilization strategies against the clubroot disease (Plasmodiophora brassicae)

The clubroot disease causes considerable yield losses in the cultivation of Brassica vegetables. At an experimental site with an elevated infection pressure of the clubroot disease and with a pH-value of 6.8 calcium cyanamide and quicklime were tested for their preventive effect against this soil-borne disease in white cabbage crops in 2007 and 2008. Calcium…

The reduction of agricultural greenhouse gas emissions

A recent study at the ETH Zurich shows that the development of agricultural greenhouse gas (GHG) emissions in Switzerland will, also in the near future, mainly depend on the development of livestock populations. Current GHG reduction measures may only play a marginal role, given their relatively high cost. Furthermore, the results indicate that the target…

Nitrogen balance of hay meadows with and without fertilization

In a paired field experiment in Oensingen (Switzerland), a fertilised and an unfertilised meadow had been established in 2001 after conversion from arable rotation. Beside the carbon budget, also the entire nitrogen budget of the two grassland fields with all input and output processes have been measured since 2006. Although the nitrogen input to the…

Sustainability of concentrate use in dairy husbandry

Prices of animal feed play an important role for the use of concentrate and basic-ration feedstuffs in dairy husbandry. Calculations made with the SILAS model calculation system show that it is economically efficient to increase concentrate rations for dairy cows when feedstuff prices decrease. Sustainability analyses taking into account economic as well as social and…

Current examples from animal breeding research in Switzerland

The increasing demand of safe and healthy animal products coupled with a decreasing availability of resources and ecological and economic pressures is considered a major challenge for animal production in the future. Research in animal breeding and genetics is therefore warranted in Switzerland. The selective mating of sires and dams represents a crucial step at…

PASTO: quality of mountain beef

The aim of this study was to characterise mountain-produced meat. A total of 88 steers of the hardy Swiss Herens breed were compared. The animals came from extensive grassland mountain farms in the Alps (1200 and 1800 m above sea level) and in the Jura (1200 m) and from a lowland farm practising intensive fattening…

Genetic aspects of the trial animals in the project “Pasture based milk production”

The Swiss College of Agriculture (SCA) in Zollikofen is searching for the ideal cattle type well adapted for a pasture-based milk production scheme. In 2007, the SCA launched a project together with the “KTI” (Swiss Confederation’s innovation promotion agency), the IG Weidemilch (Federation of farmers interested in pasture-based milk production), Swissgenetics (major Swiss AI company)…

DOC trial: yields from arable crops treated with halved and commonly used applications of fertiliser, 1992 to 2005

In the DOC trial in Therwil (Canton of Basel, Switzerland), organic and conventional farming systems have been run for 30 years, differing mainly in fertilisation and plant protection. Three systems are being compared – bio-dynamic (D), bio-organic (O) and conventional (K) – as well as two supplementary variants: conventional with mineral fertiliser only (M) and…

Soil analysis with X-ray fluorescence spectometry

The aim of this study was to characterize a field of Agroscope Reckenholz research station regarding its soil constituents with X-ray fluorescence spectrometry (XRF) and other analytical methods. In addition, criteria for homogeneity were to be determined in order to assign homogeneous lots for long-term agricultural experiments. In the first part, a method was developed…

Environmental impact of agricultural buildings

Life-cycle assessments (LCAs) are based on numerous databases in the energy, transport, waste disposal, chemicals, agricultural processes and facilities spheres. Agroscope Reckenholz-Tänikon Research Station ART has expanded the data specifically pertaining to agriculture in the ‘buildings’ sphere. The comparison of four different dairy barns shows that by opting for a multi-building loose-housing system in a…

Varieties of tall fescue and timothy tested

The two research stations Agroscope Reckenholz-Tänikon ART and Agroscope Changins-Wädenswil ACW conducted variety trials with tall fescue (Festuca arundinacea Schreber) and timothy (Phleum pratense L.), at six and seven locations respectively, in the years 2006 to 2008. The following traits were systematically assessed: yield, juvenile development, vigour, competitive ability, disease resistance, persistence and digestible organic…

Infestation of winter wheat – monitorin of harvest samples from growers`field

In 2007 and 2008, Fusarium infestation and the content of deoxynivalenol (DON) in nine winter wheat varieties was investigated in three trials on two no-till farms. The trials formed part of a study on the feasibility of small-plot variety trials under no-till conditions. This paper mainly describes the Fusarium and mycotoxin situation. In Baggwil in…

Fusaria and mycotoxins in wheat – monitoring of harvest samples from growers`field

In a 2-year investigation, harvest samples from Swiss growers’ wheat fields were examined for Fusarium species incidence and data on cultivation techniques were collected. In addition, the content of the mycotoxin deoxynivalenol (DON) was analysed in three quarters of the samples. From a total of 248 samples originating from 16 cantons, three Fusarium species were…

Effects in winter wheat

The yield of winter wheat grown using three different farming systems (‘organic’, ‘extensive IP’ and ‘intensive IP’) as well as the quality and health of its grains were compared in a long-term trial on Burgrain Farm in Alberswil (Canton of Lucerne, Switzerland). In the organic farming system, the land was ploughed, fertilized with farmyard manure,…

Mesurement of aroma development during the ripening of Golden Delicious apples

In the frame of several research projects in apple breeding and conservation technology at the research station Agroscope Changins-Wädenswil ACW, key factors determining apple quality and the effect of different storage conditions on produce characteristics have been investigated. It is known that, besides classical quality parameters, such as firmness, sugar content and acidity, aroma is…

Crop wild relatives conservation

Crop wild relatives (CWR) are defined as those wild species that are more or less closely related to crops and exchange genes with the latter. Therefore, CWR are an important part of the gene pool of crops. They also have a high potential for crop breeding as well as for their potential use as novel…

The market for meat from the Herens breed in the Valais. Prospects for the organisation of the supply chain

Few market studies have been undertaken of Hérens cattle meat and its development potential. Our paper highlights a situation of high demand and insufficient supply. Nearly half the volume produced is used for home consumption by the farmers, or sold through direct sales, whilst our survey shows that consumer demand and willingness to pay are…

EUROCROP: Research strategy for European arable farming

EUROCROP was a concerted action to develop a research strategy for European arable farming. Research institutes and various stakeholders drew up the main research priorities for individual arable crops and for six transversal elements: “farming systems”, “farm economics”, “outlets and markets”, “quality of agricultural products”, “environmental impacts” and “socio-economic issues”. The social relevance and priority…

Rural innovation networks: from knowledge to development

When do agricultural producers invest in new harvesting technology, change the rotation of crop and fertilisation, reorient their production or use new marketing channels? Over the last years the use of advanced knowledge and technology in agriculture has become more and more important. Farmers, as well as agro-industry companies that provide agricultural input or buy,…
