MACIAS DUARTE, Rubén et al. Irrigation deficit and hydrogel application in olive productivity in desert regions. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.2, pp.393-404. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i2.1751.

The over exploitation of the water table and the lack of water in the semi-desert region of northern Sonora represents a serious problem. For this reason, the objective of this work was to evaluate the effect of a 50% irrigation deficit (DR50%) and a hydrogel (H) on the yield and quality of the olive cultivation ‘Manzanilla de Sevilla’ in the semi-desert region of Caborca, Sonora, during the 2016 to 2017 cycle. The treatments evaluated were: DR50%, DR50%+H, R100% (control) and R100%+H. The results obtained indicate statistical differences in the moisture content of the soil between the DR50% and the control, with a reduction of 22.7% (2 880 m3 h-1) in the volume of water applied with the DR50% in relation to the control, without affecting the yield and quality of the fruit. The hydrogel addition showed no response in any of the parameters evaluated. The yield and quality of the fruit was statistically the same for all the treatments evaluated.
