| Sumario: | Irrigation water management in the Genil-Cabra irrigation district, located in the province of Cordoba, Southern Spain, was
studied using three irrigation performance indicators: relative irrigation supply (RIS); relative water supply (RWS) and relative
rainfall supply (RRS). All indicators have been calculated as in a global way as grouping data according to crop type, irrigation
method, soil texture, and size irrigation plots. All information of agronomic and hydraulic variables was incorporated in a Geographic
Information System (GIS) to ease its management. Results show that applied irrigations are deficit irrigations because RIS values
are relatively low. However, RWS values are greater and evaporative demand may be satisfied along crop development cycle.
RRS indicator varies less that the other two and, together with RWS, permits to know the evapotranspiration fraction covers by
rain water. The mean values of performance indicators we have calculated are very useful to know farmer’s behaviour and the
general trend, although the used sample is not significant to characterize the global irrigation district. |
