ABSTRACT
The lowbush blueberry growers of Maine need technical support and recommendations for scheduling irrigation to improve their water use efficiency. A common grower irrigation scheduling practice is to supplement rainfall to ensure that roughly one inch (2.5 cm) per week of water reaches the plants during the growing season. Another common belief is that less irrigation water is required near the Atlantic coast where temperatures are cooler and dense fog and dew occur frequently. The fog is thought to relieve plant water stress even when there is no rainfall. More water is thought to be needed at inland locations where temperatures are higher and humidity lower.
