    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

The effect of cutting treatments on grass production was studied both in the field and in experiments under controlled conditions. Cutting limited the increase in dry matter for a certain time. Thereafter dry weight of plants continued to increase at the same proportional rate as in undisturbed plants. The relation leaf blade dry weight/total dry weight was constant for vegetative grasses. When this ratio was reduced by cutting, the production of leaf dry matter increased over that of other plant parts, until the initial relation was restored.

The distribution of increases in dry matter over herbage and the rest of the plant was the same before and some time after cutting. Different levels of cutting had no effect on proportional increase in dry matter production.

A cutting height of 5 cm was optimum for herbage production after a single cut and 10 cm for repeated cuttings.

Vernalized plants gave more herbage dry matter at the first cut; vegetative ones at subsequent cuts.

With Lolium tillering stopped for a certain period after cutting, whose length decreased with increase in reserves or cutting height. These factors had no effect on tillering of Dactylis.
