The effect of irrigation of an orchard of nectarine cv. Flamekist with reclaimed sewage water on fruit quality and storage quality was investigated during 1992 and 1993. Irrigation with reclaimed sewage water was also combined with additional nitrogen fertilizer, summer pruning and reduced irrigation during the month before harvest, and the effects compared those of irrigation with fresh water. Average fruit size was unaffected by the treatments, although there was a higher percentage of fruits >70 mm in diameter from trees irrigated with fresh water. Trees with additional N fertilizer had fewer fruits and delayed ripening. The treatments did not affect firmness or titratable acidity at harvest, but fruits from trees irrigated with sewage water had higher soluble solids contents than those from fresh water irrigation. Summer pruning further enhanced, and extra N decreased, soluble solids contents in 1 out of 2 seasons. After 6 weeks of controlled atmosphere storage, 35-50% of fruits from fresh w

ater and from sewage water irrigation had healthy flesh, but fruits from fresh water irrigation were less juicy. The only treatment which gave a majority of fruits with acceptable eating quality after storage (80-90%) was reduced irrigation with reclaimed sewage water during the month before harvest.
