“…Regarding the cumulative N2O emissions, the values reported in this work were close to the values obtained by Álvaro-Fuentes et al (2016) and Maris et al (2018) for sprinkler-irrigated maize systems in the Ebro Valley (NE Spain), but lower than the values reported in the two meta-analysis published for Mediterranean conditions (Aguilera et al, 2013;Cayuela et al, 2017). These two studies reported cumulative soil N2O emissions of 4 kg ha -1 for sprinkler irrigation and cumulative N2O emissions close to 5 kg ha -1 for maize.…”

“…Recently, other investigations have determined the impact of nitrogen fertilization management on soil greenhouse gas (GHG) emissions in sprinkler-irrigated maize (Álvaro-Fuentes et al, 2016;Maris et al, 2018). However, to date there is no information about the influence of sprinkler irrigation management and, particularly, the effect of sprinkler irrigation time and frequency on GHG emissions in Mediterranean soils.…”

Irrigation management may influence soil greenhouse gas emissions (GHG). Solidset sprinkler irrigation systems allow to modify the irrigation time and frequency. The objective of this study was to quantify the effect of two irrigation times (daytime, D; nighttime, N) and two irrigation frequencies (low, L; high, H) on soil carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) emissions in a solid-set sprinklerirrigated maize (Zea mays L.) field located in NE Spain during 2015 and 2016 growing seasons and the fallow period between growing seasons. Compared with D irrigation, N irrigation increased soil water content (0-5 cm) in both growing seasons. Irrigation management did not affect CH4 emissions and the soil acted as a sink of CH4. Cumulative CO2 emissions were affected by the measurement period (growing season vs fallow) with the greatest values in 2015 growing season, being 81 and 32 % higher over the fallow period and over the 2016 growing season, respectively, due to the effect of the preceding crop, alfalfa, and a better soil moisture conditions for the microorganism activity.Similarly, cumulative N2O emissions showed the highest values in 2015, reporting values 90 and 51% greater than the fallow period and the 2016 growing season, respectively. Moreover, N irrigation increased cumulative N2O emissions by 29 % compared with D irrigation, but irrigation frequency did not affect cumulative N2O emissions. Irrigation time did not affect cumulative N2O emissions scaled per grain yield or per N uptake because N irrigation increased maize yield by 11% compared with D irrigation. Due to the lack of differences in the scaled N2O emissions, N irrigation should be consider as an appropriate strategy to optimize grain yield without compromising soil GHG emissions per unit of grain yield in Mediterranean agroecosystems.

“…All these studies, however, were carried out under rainfed conditions. In irrigated conditions, some researches have been conducted to find out the effect of different tillage systems and irrigation management on soil CO2 and CH4 emissions (Zornoza et al, 2016;Forte et al, 2017;Maris et al, 2018;Pareja-Sánchez et al, 2019), but none of them took into consideration the interaction between tillage and irrigation systems.…”

“…In the last decade, several experiments have been performed to study agronomical aspects of sprinkler irrigation systems regarding to the crop water requirements and crop performance under Mediterranean climatic conditions (Cavero, Beltrán, & Aragües, 2003;Cavero, Medina, & Montoya, 2018;Robles, Playan, Cavero, & Zapata, 2017). However, limited studies have been done to assess the impact of different agronomical practices on N 2 O emissions in Mediterranean climatic conditions under irrigation and mostly focused on nitrogen (N) fertilization management (Álvaro-Fuentes et al, 2016;Maris, Lloveras, Vallejo, & Teira-Esmatges, 2018). Similarly, a limited number of studies have been conducted to compare the effect of different tillage practices on N 2 O emissions in Mediterranean climatic conditions and all these studies were performed under rainfed conditions (Plaza-Bonilla et al, 2014;Plaza-Bonilla et al, 2018).…”

Irrigation and soil management can impact soil nitrous oxide (N2O) emissions. Flood and sprinkler irrigation systems together with conventional tillage are the main practices used in the high yielding maize systems in Mediterranean Spain. The objective of this field work was to quantify the effect of the irrigation system (i.e., flood, F; and sprinkler, S) and the soil tillage system (i.e., conventional tillage, CT; no‐tillage maintaining the maize stover, NTr; and no‐tillage removing the maize stover, NT) on the N2O emissions from the soil during 3 yr (2015, 2016, and 2017). S irrigation, with mean values of 1.35 kg N2O‐N ha−1 yr−1 throughout the 3 yr, obtained 42% lower N2O emissions than F irrigation. On average of the three growing seasons, yield‐scaled N2O emissions by grain yield and by grain N uptake in F irrigation were two‐fold higher than in S irrigation. Moreover, in one out of three growing seasons (2017), no‐tillage systems (i.e., NTr and NT) showed greater yield‐scaled N2O emissions compared with CT. The higher maize grain yield with the S irrigation compared to F irrigation, as well as the lower N2O emissions reported under S irrigation resulted in the reduction of the yield‐scaled N2O emissions. Our findings highlight the role of sprinkler irrigation decreasing N2O emissions in comparison to flood irrigation in Mediterranean agroecosystems.
