The effect of water restrictions on apple orchard productivity in British Columbia's Okanagan Valley Wigington, Ian
This thesis examines the relationship between water and yield for apples in the Okanagan region of British Columbia. This is accomplished through a model which simulates the water/yield relationship in tree fruits. Two soil types, two rootstocks, and two irrigation systems were included in the simulation. The results of the simulation indicate that Okanagan orchard irrigation water requirements are substantially lower than present irrigation application rates. Using sprinkler irrigation, irrigation requirements for silt-loam soils amounted to 30% of present application rates, while for sand soils 42% of present application rates were required. Trickle irrigation requirements were determined to be 71% of sprinkler requirements for similar yields.
