Abstract

In order to identify an irrigation system for the pear cultivar Conference capable of both increasing yield and fruit weight and saving water and ensuring a balanced growth of the tree, four irrigated treatments were compared with a non-irrigated control: two with irrigation provided throughout the season and two with Regulated Deficit Irrigation (RDI). The RDI system, with 100% replenishment of the ETc limited to the period extending from 60 days after flowering to harvest time, showed to be the best; in comparison with the non-irrigated control, yield increased by 57%, fruit weight by 16% and the gross margin by 101%, while water savings amounted to 28% compared to irrigation with full replenishment of the ETc.
With the RDI system, the trees showed a positive reduction in vegetative growth together with a more ample flowering, resulting in a larger quantity of fruit, which were brought to a higher fruit weight by the irrigations carried out in the period of maximum productive efficiency.
