Agriculture`s contribution to food security

In addition to providing other multifunctional services, Swiss agriculture contributes to assuring that the population is supplied with foodstuffs. In the event of a crisis, supplies do not depend primarily on domestic production, but on the foodstuffs available in the mandatory stockpiles and the supply chain. However, the maintenance of production potential is essential for…

Relationship between test weight and several quality parameters in wheat

Test weight has been used as a quality parameter of cereals in a large number of countries and is still employed to determine the price level. Literature studies showed controversial results concerning the relationship between test weight and flour yield as well as with other quality parameters. In this study, the data of a wide…

Validation of a method for molecular genotyping of fruit varieties

Microsatellite based genotyping for the identification of cultivar varieties in crop plants is nowadays a widely used and proven method. Many variations of this method are used that differ sometimes strongly with respect to work load and efficiency. We have developed a robust and efficient method that we use with great success since several years.…

Optimized N-fertilization in the production of chicory

During three years between 2004 and 2006 different levels of nitrogen including various strategies of temporal partitioning were studied with the chicory variety Vintor. The objectives of these experiments were to assess the impact of N fertilization on the development and quality of the chicory roots and thereafter on the performance of the roots at…

Investigation on feed intake of pregnant heifers and first lactating cows in Switzerland

In dairy herds, about one third of the cows are primiparous. These animals are still growing and therefore have specific nutrition requirements. The aim of this project was to show how heifers and primiparous cows are fed on Swiss dairy farms. Feeding, production and health data were collected on 60 Swiss farms for 252 animals.…

What are the facrors influencing the disbanding of a farming collective?

In January 2006, the Agroscope Reckenholz-Tänikon Research Station ART carried out a survey of all farming collectives (FCs) in Switzerland. The aim of the survey was to obtain findings on the organisation of the FCs, as well as on the satisfaction levels and communication and conflict-management strategies of the partners. In the present study, logistic…

The Swiss Dairy Inspection and Advisory Service (DIAS) – a review of a ten year old pioneer work

For ten years until the extension of equivalence with EC legislation to all food products of animal origin, the Swiss Dairy Inspection and Advisory Service DIAS has delivered competent services to ensure that the requirements for export of the Swiss dairy sector were met with. DIAS has contributed to a high degree to attain high…

Dairy cow feeding and folic acid in milk

A trial with 36 dairy cows in mid-lactation allotted to 3 groups was carried with the aim to evaluate the possibility of increasing the concentration of folic acid in milk by feeding rations naturally rich in folic acid. This experimental ration contained brewery waste, cubes of alfalfa, brewers’ yeast and wheat germ in addition to…

Influence of nitrogen fertilisation on baking cereals quality

A three years study was carried out in two experimental sites to analyse the influence of increasing nitrogen fertilisation on baking quality parameters of wheat. Varieties of various quality levels were studied. An increasing nitrogen fertilisation had a positive impact on the majority of the quality parameters. Yield, protein content and quality increased, as well…

Life cycle assessment of energy crops

The environmental impact of bioenergy production from biomass strongly depends on the crop cultivation. This study looks into the ecological optimisation of biomass cultivation answering following three questions: What is the environmental advantage of organic over integrated farming? Which crops are suited for biomass production? What other key factors have to be considered for a…

Noxious weeds in set-aside areas: results of a nationwide observation network

Fallow land sown with a wildflower seed mixture is one of the major set-aside areas promoted by the Swiss legislation in order to enhance biodiversity in the landscape. Still, the installation of such areas on arable land raises concerns about their potential to contribute to the dissemination of noxious weeds. In order to gather information…

Agroscope research programs

The three Agroscope research stations, Changins-Wädenswil ACW, Liebefeld-Posieux ALP and Reckenholz-Tänikon ART, will jointly carry out three multidisciplinary research programs during the period 2008 – 2011. “ProfiCrops” aims at developing, preparing, evaluating and exchanging information in order to ensure a future for Swiss vegetable production in a largely liberalized market and to reinforce the confidence…

Agroscope research master plan 2008-2011

The Agroscope research master plan provides information for interested and involved players, supports coordinated research and acts as a tool for the planning and legitimisation of research work. It was drawn up by the Swiss Federal Office for Agriculture in collaboration with the Agricultural Research Council and Agroscope. Agroscope’s research aims and focal points for…

Occurence of lysinoalanine in milk and dairy products

Lysinoalanine (LAL) is produced as an undesirable secondary product during alkaline treatment of proteins or the heating of foodstuffs containing proteins. Because of their closeness, dehydroalanine reacts with the lysine ε-amino group. Since the reaction is largely irreversible, the value of the lysine content is almost completely or totally blocked. Due to an improvement in…

Breeding progress on triticale obtained in Switzerland by Changins Research Station

Triticale is bred in Switzerland since 30 years. Based on observations on breeding lines between 1988 and 2006, this article analyzes the main breeding progresses achieved. Agronomic performances of the 2281 lines show that:productivity per cm height was improved with a rate of 1,4% per year protein yield was increased by 1,4 dt/ha, thus progressing…

Future societal demand for multifunctionality

Society’s demand for multifunctional benefits is the basis of direct payments in Swiss agricultural policy. However, societal demand changes over time. Therefore this explorative study tries to evaluate future demand for landscape benefits in different Swiss regions. The results of the expert survey show that demand can be differentiated into production-, recreation-, and ecological orientated…

Effects of suboptimal fertilization on arable crops

The production of high yields and adequate product quality requires a sufficient and balanced supply of the soil with nutrients. The field trial, conducted since 1989 for purpose of demonstration, shows the impact of different fertilizer forms (organic and mineral fertilizer) on the one hand and the effects of an unbalanced fertilization on the other…

Soil organic matter content after eleven years of no-till and plough

The organic matter content of the soil was analyzed on a medium textured slightly humic soil at the Inforama Rütti in Zollikofen which had been cultivated either with no-till or plough over eleven years. In several soil layers down to 40 cm the organic matter content as well as bulk density were analyzed. Due to…
