“…Much recent research (e.g. Chopart et al, 2007;Zapata et al, 2009;Salvador et al, 2011;Andrés and Cuchí, 2014) from different parts of the world has focused on irrigation scheduling due to the high flexibility of sprinkler irrigation. A common conclusion reached is that irrigation scheduling is important to maximize crop production.…”

Farmers are being encouraged to shift from conventional surface irrigation to sprinkler irrigation in the semi-arid region where coarse-textured soil is predominant in order to improve irrigation efficiency, but their irrigation and fertilization are currently scheduled by the traditional methods obtained from surface irrigation due to insufficient knowledge of the relatively new technology of sprinkler irrigation. This often results in an inefficient use of water and nutrients and a decreased crop yield. The objective of this paper was to quantify the response of maize growth, nitrogen uptake, yield, yield components, water productivity and nitrogen agronomic efficiency to different irrigation and nitrogen application rates under semi-arid conditions and to determine an optimal irrigation and nitrogen regime for sprinkler irrigation. Field experiments were conducted on a very coarse sandy soil irrigated by a lateral move sprinkler system in the Inner Mongolia Autonomous Region in 2012 and 2013. Three irrigation levels of 40, 70 and 100% of evapotranspiration (ET c ) and four nitrogen application rates of 80, 160, 240 and 320 kg ha -1 were tested in 2012. Whereas in 2013, four irrigation levels of 40, 70, 100 and 130% of ET c and four nitrogen application rates similar to the 2012 experiments were used. For the very coarse soil tested, the irrigation level demonstrated a substantially more important influence on plant growth than nitrogen application rate. A higher irrigation level produced a significantly greater plant height, leaf area index (LAI), dry matter above ground, plant nitrogen uptake, yield and nitrogen agronomic efficiencies (NAE) when irrigation level was between 40 and 100% ET c . However, when the irrigation level exceeded 100% ET c , a reduced yield and NAE was observed. In 2012, the nitrogen application rate of 160 kg ha -1 usually gave a slightly higher yield and irrigation water productivity (IWP). Whereas in 2013, the nitrogen application rate of 240 kg ha -1 resulted in the greatest yield and IWP. No significant difference in yield, IWP and NAE was observed between the treatments with nitrogen application rates of 160 and 240 kg ha -1 for both 2012 and 2013 experiments. A management practice of irrigation at 100% ET c, along with nitrogen application rate of 160 kg ha

“…Calculations were automated through the utilization of EMR 2.0 (Irrigation Land Environmental Tool -EMR -, from its Spanish abbreviation, Causapé, 2009a). This methodology has been applied to several irrigated areas in the Middle Ebro River Basin (Causapé, 2009b;García-Garizábal et al, 2009, 2011Abrahão et al, 2011a;Skhiri and Dechmi, 2012;Andrés and Cuchí, 2014).…”

“…Salvador et al, (2011) applied water use efficiency and water productivity indicators to evaluate the irrigation performance and its variability between irrigation systems and crops in the Ebro basin (Spain). Likewise, Andrés and Cuchí (2014) used water productivity indicators to analyze the water use and the quality of irrigation in their study area. Zwart and Bastiaanssen (2004), observed a broad interval in the average values of crop water productivity (wheat: 0.6 -1.7 kg/m 3 ; rice: 0.6-1.6 kg/m 3 ; cotton: 0.41-0.95 kg/m 3 and maize: 1.1-2.7 kg/m 3 ) and, pointed out its application to increase or maintain the same crop production reducing water supply about 20 to 40%.…”

A study of the assessment of the irrigation water use has been carried out in the Spanish irrigation District "Río Adaja" that has analyzed the water use efficiency and the water productivity indicators for the main crops for three years: 2010-2011, 2011-2012 and 2012-2013. A soil water balance model was applied taking into account climatic data for the nearby weather station and soil properties. Crop water requirements were calculated by the FAO Penman-Monteith with the application of the dual crop coefficient and by considering the readily available soil water content (RAW) concept. Likewise, productivity was measured by the indexes: annual relative irrigation supply (ARIS), annual relative water supply (ARWS), relative rainfall supply (RRS), the water productivity (WP), the evapotranspiration water productivity (ETWP), and the irrigation water productivity (IWP).The results show that in most crops deficit irrigation was applied (ARIS<1) in the first two years however, the IWP improved. This was higher in 2010-2011which corresponded to the highest effective precipitation Pe. In general, the IWP (€.m -3 ) varied among crops but crops such as: onion (4.14, 1.98 and 2.77 respectively for the three years), potato (2.79, 1.69 and 1.62 respectively for the three years), carrot (1.37, 1.70 and 1.80 respectively for the three years) and barley (1.21, 1.16 and 0.68 respectively for the three years) showed the higher values. Thus, it is highlighted they could be included into the cropping pattern which would maximize the famer's gross income in the irrigation district.
