Montoro, P. López-Fuster, E. Fereres] Irrigation scheduling services (ISS) provide farmers with recommendations on timing and amount of irrigation, thus contributing to improving on-farm water management. There are wide variations in the level of services, from providing regional water use guidelines to local, on-farm advisory services. An ISS (ISS-ITAP) was created in 1988 in Albacete, Central Spain, a province encompassing 100,000ha which are irrigated mostly with groundwater. The ISS-ITAP first offered general information on crop water requirements (ET), and after 1994 field-specific scheduling services were provided to growers. By 2005 the ISS-ITAP had expanded its services to over 33,500ha, corresponding to about 30% of the irrigable area. The evolution of irrigation performance in a number of individual farms was followed over 10years, and it was found that the proportion of fields which were adequately irrigated increased from 50 to over 70% in that period. Meanwhile, the proportion of deficit-irrigated fields declined from 20 to 10%, while the proportion of over-irrigated fields which also had initially decreased from 20 to 10%, went back to 20% at the end of the study period. To assess the benefits and costs of the ISS-ITAP, a comparison of the yields achieved in the scheduled farms against those obtained in the rest of the province was carried out. When the Service was evaluated in economic terms, using information from 2003, the pay-back was 2years and the internal rate of return was 59.1%, highlighting the high returns on the public funds invested by ISS-ITAP to provide irrigation advisory service to growers in the Albacete province.
