    • The ability of nitrogen fertilisers to break the lifecycle of gastro-intestinal nematodes 

      Bennett, Jack (Lincoln University, 2017)
      Current gastrointestinal nematode (GIN) control relies heavily on chemical anthelmintic, targeting nematodes within the host ruminant. Most of the lifecycle occurs outside of the host so targeting the free-living population ...
    • The accuracy and application of some subjective judgements used in wool research 

      Dunlop, A. A. (Canterbury Agricultural College, University of New Zealand, 1942)
      In New Zealand during the last two or three years, a scheme of wool research termed “Wool Survey” which exploits the naturally occurring variation among animals, has been developed on an extensive scale. Visual judgements ...

      In the Starborough-Flaxbourne area the local farming community, alarmed at the increasing hill slope erosion, set up a soil conservation group. Accelerated erosion was a symptom of the past 12 years of below average rainfall. ...
    • Adjustments of seasonal feed-supply to seasonal requirements of animals 

      Scott, M. J. (New Zealand Grassland Association., 1936)
      Because of the differential growth of herbage plants throughout the year and because of weather hazards, the most difficult problem of the stock-raiser is the provision of an adequate supply of feed for every day in the ...

(Ecological Society of America, 2014-09)
      Intensively managed grasslands are globally prominent ecosystems. We investigated whether experimental increases in plant diversity in intensively managed grassland communities can increase their resource use efficiency. ...
    • Agronomic effectiveness of vermicompost in grassland systems 

      Abernethy, Paige (Lincoln University, 2017-10-30)
      Vermicompost is the proccess of organic waste breakdown by red worms (Eisenia foetida) and other microorganisms. Vermicompost increases the bioavailability of nutrients which encourages the growth of plants and germination ...
    • An agronomic evaluation of subterranean clover cultivars 

      Scott, W. R. (Lincoln College, University of Canterbury, 1969)
      The permanent pasture based on a grass-clover association and utilised in situ by grazing stock is the basis of New Zealand's chief primary industries. Although white clover is the main legume species used for this purpose ...
    • An agronomic evaluation of Subterrenean clover cultivars 

      Scott, W. R. (New Zealand Grassland Association., 1971)
      The seasonal production of six cultivars of subterranean clover, Geraldton, Yarloop, Woogcnellup, Clare, Mount Barker and Tallarook, was evaluated under cutting in North Canterbury. Woogenellup and Clare produced more ...
    • Agronomic evaluation of Trifolium ambiguum M. Bieb 

      Paljor, Sonam (Lincoln College, University of Canterbury, 1973)
      Caucasian clover (T. ambiguum M. Bieb.) was studied to assess its suitability in revegetation programmes on eroded mountain areas. One hexaploid and two diploid strains of T. ambiguum were compared with Grasslands Huia ...
