Nutritive value of grassland plants: contents of cell wall constituents

“The main constituents of the cell wall, e.g. crude fiber, ADF, NDF and lignin, were analysed in 10 important varieties of grassland plants. The results of 555 analysed samples give a better knowledge of  the changes with regard to the content of cell wall constituents during the growing season. Within the same plant variety and…

71 varieties of perennial ryegrass tested

In the years 1998 until 2000 the two research stations Zürich-Reckenholz and Nyon-Changins tested 71 varieties of perennial ryegrass (Lolium perenne L.) under our growth conditions. Considerable progress was observed in agronomically relevant properties like competing ability, persistence and resistance to bacterial cancor and rust.<br><br>-Early to intermediate varieties: Aruga, Aberkite, Arvella, Lipresso, Marmota and Salamandra<br><br>-Intermediate…

Nutritive value of grassland plants: dry matter, crude protein and non-structural carbohydrates contents

Ten main grassland species were cultivated in pure stand in three experiments located at different altitude. During two years their chemical composition was regularly assessed from the beginning to the end of the growing period. The digestibility of the organic matter was also measured with different laboratory methods and in feeding trials with sheep. This…

Effect of no-tillage on nutrient content and organic matter of the soi, Pratique du semis direct en grandes cultures: effets sur la structure du sol

In the long-term field trial “Oberacker” at Zollikofen (Switzerland) the content of organic matter and macro-nutrients in the soil was analysed to determine the effect of no-tillage without any soil disturbance and conventional tillage with mouldboard plough.The amount of nitrogen mineralised during the year was similar in both treatments. However, nitrogen mineralisation in spring was…

Effect of no-tillage on yields (1995 – 1999)

“In the long-term field trial “”Oberacker”” at Zollikofen (Switzerland) crop yields were measured to determine the effect of no-tillage without any soil disturbance and conventional tillage with mouldboard plough. The collected data of the first five years of trial with the field crops winter wheat, winter barley, silage corn, sugarbeets, and potatoes were compared. Whereas…

Field inspections 2000

The field inspections for seed certification of cereals, hybrid maize, grain legumes, red clover and forage grasses were carried out on 8‘945 ha in 2000. In cereals 92,5 % of the registered area was admitted during field inspection, 2,1 % was refused and 5,4 % was withdrawn from field inspection. Hail damage, presence of other…

Swiss List 2001-2002 of recommended varieties of forage plants, Variation factors of the nutritive value of silage maize

In the years 1997 to 1999 we tested 45 varieties of Lolium multiflorum var. Italicum and 24 varieties of Lolium x hybridum at five different experimental sites. All varieties were grown in pure stands and in mixture with red clover. The parameters assessed were forage yield, juvenile growth, competing ability, resistance to diseases, digestibility and…

Corvus and Pica: two new red clover cultivars of the persistent Mattenklee type

Two new red clover cultivars, CORVUS and PICA, of the persistent “Mattenklee” type are being released in Switzerland. They have been selected for being less aggressive in mixtures. Their first year yield is slightly lower than that of the known “Mattenklee” cultivars. However, they have an excellent level of resistance against stem nematodes, powdery mildew…

Sustainable and competitive fruit production: a challenge for the production chain and for research

Fruit growers aim to produce fruit economically and in an environmentally friendly way. Research should find the relevant solutions. Moreover, the framework of agricultural politics and the increasingly open markets are strong challenges for the fruit industry. The following examples will give an insight into the activities of the Federal Research Station Wädenswil: apple breeding…

Varietal diversity in horticulture

New vegetable varieties must be grown at different regional sites to evaluate their specific potential with respect to time and duration of the harvesting period, their yield and quality. Additionally, cultivars with resistance or tolerance to pests and/or pathogen must be tested under defined conditions in the field. In future, more information is needed on…

Fire blight, a permanent threat

Fire blight is the most damaging disease of pipfruits. The situation has dramatically changed in Switzerland during the last few years, when the disease was found in several new regions (e.g. cantons of Zurich, Thurgau, St. Gall, Lucerne, etc.). A large number of host plants can be affected by fire blight during the season. There…

Plant protection chemistry – at the service of applicators, consumers, the environment and the economy

Pesticides (plant protection products, PPP) are designed to defend plants against attacks of insects, fungi or other harmful organisms. They contain active ingredients with considerable biological activities which usually extend somewhat beyond the purpose they are intended for. Their registration process therefore takes into consideration both efficacy and side effects and evaluates them in a…

Cropping technique: the key to top quality vegetables

Vegetable production is without doubt the most diverse and demanding branch of Swiss Agriculture. Although neither crop husbandry nor the structures of cropping and farming systems differ significantly from that of other agricultural production areas, the crop diversity and the specific market requirements demand outstanding know-how and high organisational and economic capabilities from the producers.…

Does the grass composition of highland pastures differ from those of lowland leys?

In this paper, we compare the botanical and chemical compositions of grazed grassland located at various altitudes between 600 and 2100 m a.s.l., as part of a study on the relationships between the characteristics of grass and those of Swiss hard cheese. The lowland leys are composed only of grasses and legumes and their botanical…
