    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.

Approximately 600,000 tons of maize were produced annually in Nigeria. Maize was the main grain crop in southern Nigeria and its production in the middle belt was rapidly increasing. Most of the crop was eaten as dry grain, a little before maturity. A preference was recorded for floury varieties of maize in southern Nigeria. This preference depended on the greater yield of flour per unit weight of grain in the floury varieties over flint and dent varieties. Grain type, plant height, time to maturity and grain colour allowed distinction of four local maize types.

Some of the newly introduced maize types from Central America outyielded the local varieties by a wide margin: 1200-1500 lb per acre for the local varieties and 2500-3000 lb for the introduced ones. Once. this difference proved to be due to greater longevity of the top leaves of an introduced variety.

Information on the agronomy, distribution and utilization of maize was used to draw up aims for a Nigerian maize breeding programme. One of the aims, a yellow flint maize of medium duration, was achieved in a synthetic variety ESI through an intravarietal gametic selection for combining ability. Later observations showed that advanced-stage inbred lines from several sources should be utilized.
