Abstract
The objective of our studies performed on highbush blueberry (Vaccinium corymbosum) was to analyse the effects of moderate or strong water deficit in year n, on yield, harvest index and fruit quality in year n and n+1. The effects of 2 week long dry periods occurring at different phenological stages (fruit growth, maturation and after picking) were analysed.
The more critical stage was fruit growth.
A water stress occurring between late May and late June strongly affected fruit production by increasing fruit size.
In year n+1, only the drought treatment after picking affected fruit production by decreasing the number of fruit.
