2.7. Measurements of yield and irrigation use efficiency
At final harvest, fruit number and total fresh mass of fruit for each individual plant were recorded. Fruit from individual plant were examined for blossom-end rot (BER) incidence
and assessed for the severity of disorder under each treatment. Fruit were oven-dried at 71 1 8C to a constant mass and dry mass determined. Shoots and roots of each individual plant were collected, weighed, and oven-dried to determine the distribution of plant dry mass. Roots were separated from shoot and washed to remove the medium. They were oven-dried at 71 1 8C to a constant mass and dry mass determined. Irrigation use efficiency was determined by dividing the total fresh mass of fruit by the volume of irrigation water (litres) applied to the plant.
