    • Canterbury’s irrigation water resources 

      Morgan, Matthew J.; Bright, John C. (South Island Dairy Event (SIDE)., 2003)
      With 58% of all water allocated for consumptive use in New Zealand, and 70% of the nation’s irrigated land, Canterbury is already critically dependent on water resource development in the form of irrigation and stock ...
    • A case study of the effect of a key innovation on farmers adoption behaviour 

      Hornay, Filomeno (Lincoln University, 1996)
      Irrigation is one of the important components to increase agricultural production, primarily in areas where the annual rainfall is inadequate. There are many areas in New Zealand which are subjected to drought due to ...
    • Cocksfoot pasture production in relation to environmental variables 

      Mills, Annamaria; Moot, Derrick J.; McKenzie, Bruce (New Zealand Grassland Association., 2006)
      The effects of temperature, water and nitrogen on pasture production of an 8 year old ‘Wana’ cocksfoot pasture were quantified at Lincoln University, Canterbury. The maximum dry matter (DM) yield was 22.0 t/ha/yr when ...
    • The comparative profitability and productivity of a sample of irrigated and non-irrigated farms in the Ashburton-Lyndhurst area of Mid-Canterbury, New Zealand 

      Stewart, J. D. (Lincoln College., 1963-06)
