Four crops of off-white hybrid mushrooms were irrigated with tap water and 4 crops were irrigated with tap water containing 2.8 x 10-2 M CaCl2. Addition of CaCl2 to the irrigation water significantly improved colour (L value) at harvest without reducing yield or affecting mushroom DM content or size. The Ca concentration of fresh mushrooms was significantly increased by the treatment in both the second and third flushes of the crop cycle. The concentration of Cu, which was less abundant and more evenly distributed between the various mushroom tissues than Ca, was not affected by treatment. Postharvest browning was significantly reduced by treatment in mushrooms from the second and third flushes. Ca concentration was significantly and positively correlated with colour at harvest, while Cu concentration was significantly negatively correlated with colour. The ratio Ca:Cu had the most significant positive correlation with colour at harvest.
