“…As a consequence of the factors mentioned above, in addition to non‐irrigation‐related costs and amortizations, the net land productivity (LP n ) for alfalfa is 21% higher in the study areas of Aragon (Trillo, ; MAGRAMA, , ; Montero et al ., ) than those located in Utah (Scherer, ; O'Brien et al ., ; Utah Agricultural Statistics‐Utah Department of Agriculture and Food. National Agricultural Statistics Service (UDAF‐NASS), 2013; Utah State University Cooperative Extension (USU), ), on average.…”

“…These decisions are made to maximize their net incomes (Luquet et al, 2005). In this regard, irrigation uniformity plays a relevant role in investment and operational costs of centre pivots and, hence, in farmers' profits (Montero et al, 2013). However, social factors such as education, social status, water governance or cultural context, among others, also affect these decisions (Leeuwis and Van den Ban, 2004).…”

This study is an analysis of the influence that the socio‐economic context may have on irrigation performance. The main objective is to provide useful information to support the decision‐making processes of farmers, water user associations, policy‐makers and agritech companies. For this purpose, 34 centre pivots were evaluated in Aragon (Spain) and Utah (USA). Utah has a lower agricultural production potential than Aragon, and crop production is a secondary activity with respect to livestock production on many farms. In Aragon, farms are mainly devoted to crop production. These and other features may bias farmers' decisions regarding investment, operation and maintenance of their irrigation systems. This bias may be the underlying cause of the lower irrigation uniformity obtained in Utah. Coefficients of uniformity (CU) averaged 90% in Aragon and 80% in Utah. The gap between the actual and potential (90%) CU translates into an estimated net land productivity reduction of −18% (€66 ha−1, US$89 ha−1) in Utah. Measures aimed at closing this gap could cost less than €15 ha−1 (US$20 ha−1). Multidisciplinary approaches are required to quantify these gaps and to understand their causes in order to bridge them in a cost‐effective manner. Copyright © 2016 John Wiley & Sons, Ltd.

“…El paso del riego por gravedad a riego por goteo y/o aspersión genera impactos inmediatos de mayor productividad y menor consumo de agua por unidad de tierra. Esto permite, a su vez, expandir las áreas irrigadas con la misma cantidad de agua y, por ende, es una forma indirecta de incrementar el riego ( Montero et al, 2013;Palada y Bhattarai, 2012;Rodrigues et al, 2009). .…”

“…Las grandes ventajas del pivote central como sistema de riego, han despertado el interés entre los productores agrícolas, no solo por el menor costo de inversión por hectárea regada (a mayor longitud del equipo), sino también por otras características como su versatilidad para ser utilizado en diferentes condiciones de suelo, clima y cultivo, alto grado de automatización, posibilidad de aplicar cargas diferenciadas de agua de acuerdo a las necesidades reales del cultivo, inyección de agroquímicos y la uniformidad de aplicación del agua, la cual será alta cuando el diseño del equipo en fábrica, montaje en el terreno y operación, se ajusten a las características de la explotación y demanda hídrica del cultivo según sea su etapa de desarrollo (Montero et al, 2013).…”

ResumenEl uso del agua para la agricultura en regiones bajo condiciones de escasez y bajas eficiencias, requieren de investigación, innovación y una apropiada transferencia tecnológica, para mejorar la calidad del riego. Las herramientas para optimizar el uso del agua incluyen sistemas de riego presurizados, que a pesar de las ventajas tecnológicas, requieren de un mantenimiento y operación adecuados para el correcto funcionamiento agronómico e hidráulico, por que su evaluación debe ser un procedimiento rutinario. El sistema de riego por pivote central presenta ventajas sobre otros sistemas presurizados y es una buena opción para la producción de algunos cultivos. Los índices de desempeño tradicionales son el coeficiente de uniformidad y uniformidad de distribución del agua. El objetivo del estudio fue comparar la calidad del riego a partir de los indicadores de desempeño: coeficiente de uniformidad de Heermann y Hein (CUh), uniformidad de distribución (UD), área regada adecuadamente (ARA) y eficiencia de aplicación (Ea) y determinar la relación entre ellos. Las evaluaciones pluviométricas se realizaron en el norte de Sinaloa, México, en dos ciclos agrícolas (2013)(2014)(2015). La pluviometría mostró AbstractThe use of water for agriculture in regions under conditions of scarcity and low efficiencies, requires research, innovation and an appropriate technological transfer, to improve the quality of irrigation. The tools to optimize the use of water include pressurized irrigation systems, which despite the technological advantages, require proper maintenance and operation for the correct agronomic and hydraulic operation, so its evaluation must be a routine procedure. The central pivot irrigation system has advantages over other pressurized systems and is a good choice for the production of some crops. The traditional performance indices are the coefficient of uniformity and uniformity of water distribution. The objective of the study was to compare irrigation quality based on performance indicators: the Heermann and Hein (CUh) uniformity coefficient, distribution uniformity (UD), adequately irrigated area (ARA) and application efficiency (Ea) and determine the relationship between them. The rainfall assessments were conducted in northern Sinaloa, Mexico, in two cropping cycles (2013)(2014)(2015). Rainfall showed a "high quality" irrigation with a "very well-watered" area,40 Rev.
