ABSTRACT.- The expansion of olive orchards into regions with no tradition of olive production and humid climates, such as Uruguay, with more than 1200 mm of annual rainfall, calls into question the need for irrigation. In these regions, however, years with water deficit during summers are quite common. The vapor pressure deficit during summer is lower than in countries with a Mediterranean climate. The high variability in interannual water availability in the current context of climate change, with a growing tendency for extreme events to occur, emphasizes the need to evaluate the production response of olive trees to irrigation. To achieve this, three irrigation treatments were applied to Arbequina and Frantoio cultivars according to the value of the maximum crop evapotranspiration: a first treatment applying 100% ETc, corresponding to being fully irrigated; a second treatment applying 50% ETc; and a third treatment in which neither irrigation nor rain inputs occurred from the end of the pit hardening period until harvest. Results show the possibility of an increasing fruit weight and pulp/pit ratio through irrigation in the local environmental conditions. The oil content in response to irrigation was different within cultivars. Water restriction conditions did not affect the oil content of olives in Arbequina, while in Frantoio it increased it. Polyphenols in fruit increased under water stress for both cultivars. The technological applicability of the results obtained must be accompanied by an economic analysis. The results obtained highlight the need for better use of irrigation water during the growth and ripening phase of the olive fruit under a humid climate.

The increase in atmospheric temperature and alteration of the hydrological cycle are the main threats of climate change to wheat crop (Triticum aestivum L.). Furthermore, feeding a population which annually grows 1.1 %, promotes the expansion of agricultural frontier to soils with growth constraints. In this context, when in South America La Niña events occur, the cold phase of the ENSO climate phenomenon, in a greater area of the wheat crop region increases the risk of drought stress during grain filling. The aim was to study the response of five wheat cultivars to two irrigation treatments: Control and Stress. The experiment was conducted in a greenhouse using the bread spring wheat cultivars LE 2249, LE 2331, LE 2333, Baguette Premium 11 and Biointa 1001. Relative water content (RWC) was determined during the stress period, from anthesis to physiological maturity, and grain yield and its components at harvest. No significant interaction between cultivars and irrigation treatments were observed for yield per plant and RWC (P=0.3086 and P=0.0589, respectively), but it was significant for kernel weight and harvest index (P=0.0188 and P=0.0405, respectively). The cultivar LE 2333 was hardly affected by the Stress treatment, while Baguette Premium 11 and LE 2249 showed an intermediate response. In contrast, LE 2331 and Biointa 1001 were the most susceptible cultivars, decreasing their yield per plant 21.0 % (P=0.0206) and 21.2 % (P=0.0284), respectively. An early stress threshold in Biointa 1001 caused that kernel weight and RWC were not modified due to a decrease of kernels per plant. Whereas a late threshold in LE 2331 caused that both, kernel weight and RWC were affected. Cultivars with the latter type of response would be more suitable for regions with deep soils and/or with high probability of rain after anthesis.
