Trials were conducted to determine yields of narcissi bulbs at three sites in Otago and Southland in South Island, New Zealand. The effect of irrigation was tested at two sites. Mataura silt loam soils at Wendonside, Southland, gave the highest yields. On this soil type, in a season with 67% of normal rainfall, irrigation increased yields by c. 6%, with some varieties showing yield responses up to 26%. Yields over two seasons were variable, but exceeded those reported for the same varieties grown in Europe.
