“…As a consequence, the experimental results do not permit to establish firm, statistically sound differences between treatments. Similar conditions were reported by Slatni et al (2011) when analyzing the effect of CFI, AFI and FFI on irrigation performance and crop yield.…”

“…Our results suggest that both runoff and deep percolation losses can be reduced by implementing alternate furrow irrigation. Slatni et al (2011) obtained the highest and lowest average E a for FFI (100%) and CFI (72%) for blocked-end furrows, respectively. Horst et al (2007) also showed that alternate furrow irrigation resulted in improved water conservation and increased water productivity.…”

“…By facilitating horizontal (lateral) water movement, alternate furrow has potential to reduce water losses via deep percolation and runoff. A number of researchers have reported that using alternate furrow irrigation reduces irrigation water use, often decreases crop yield, and results in an increase in water productivity (Stone et al, 1982;Kang et al, 2000a;Horst et al, 2007;Slatni et al, 2011). These traits make alternate furrow irrigation convenient and economical in arid and semi-arid regions.…”

“…They reported highest irrigation performance (in terms of water productivity and application efficiency) for alternate furrow and surge flow. Slatni et al (2011) reported that large irrigation depths applied by CFI resulted in large deep percolation losses compared to AFI and FFI at a blocked-end furrow irrigated field. The highest and lowest irrigation application efficiencies were obtained for the FFI and CFI treatments, respectively.…”

Alternate furrow irrigation and surface fertigation have been known as techniques to control water and fertilizer losses. The main goal of this field study was to characterize the combined effect of these techniques on water and nitrate losses and on soil water and nitrate concentration. Two types of alternate furrow irrigation, i.e., variable alternate furrow irrigation (AFI) and fixed alternate furrow irrigation (FFI), as well as conventional furrow irrigation (CFI) were considered in the experiments. Results evidenced higher infiltration at irrigated furrows under AFI and FFI as compared to CFI. Increased lateral water movement under alternate irrigation resulted in lower water and nitrate losses via runoff and deep percolation. Water application efficiency for the CFI, FFI and AFI strategies amounted to 61.3%, 71.8% and 77.0% in the first fertigation and 36.4%, 58.8% and 60.7% in the second fertigation, respectively. Nitrate runoff for the CFI, FFI and AFI strategies amounted to 32.4%, 31.2% and 25.7% in the first fertigation and 44.3%, 35.1% and 32.7% in the second fertigation, respectively. Soil water content and nitrate concentration at the upstream part of the experimental field were larger than at the middle and downstream parts for all three irrigation regimes. Overall, alternate furrow fertigation, particularly AFI, stands as a simple and practical management practice for water and fertilizer conservation in agricultural fields.Additional key words: alternate furrow irrigation; fertigation; water and nitrate losses. Resumen Distribución y pérdidas de agua y nitrato bajo fertirriego por surcos alterno y convencionalEl riego por surcos alternos y el fertirriego por superficie se han venido utilizando por separado como técnicas con capacidad demostrada para controlar las pérdidas de agua y fertilizantes. El principal objetivo del ensayo descrito en este trabajo fue caracterizar el efecto del uso conjunto de estas técnicas en las pérdidas de agua y nitratos, en el agua en el suelo y en la concentración de nitrato en el suelo. En el ensayo se consideraron dos tipos de fertirriego por surcos alternos, variable (AFI) y fijo (FFI), así como el riego por surcos convencional (CFI). Los resultados evidenciaron una mayor infiltración en los surcos AFI y FFI que en los surcos CFI. El aumento del movimiento lateral del agua en el riego alterno resultó en menores pérdidas de agua y nitrato por escorrentía y percolación profunda. La eficiencia de aplicación del agua para las estrategias CFI, FFI y AFI fue de 61,3%, 71,8% y 77,0% en el primer fertirriego, y de 36,4%, 58,8% y 60,7% en el segundo fertirriego, respectivamente. Las escorrentías de nitrato en las estrategias CFI, FFI y AFI fueron de 32,4%, 31,2% y 25,7% en el primer fertirriego y de 44,3%, 35,1% y 32,7% en el segundo fertirriego, respectivamente. El contenido de agua en el suelo y la concentración de nitrato en el extremo aguas arriba del campo experimental resultó mayor que en la parte media o en el extremo aguas abajo en las tres estrategias ensa...

“…For example, shallow wetting irrigation and shallow irrigation combined with timely fi eld drying has shown that the paddy fi eld had more suffi cient sunlight than that in fl ooding irrigation, which could increase fi nal rice yield [7][8][9]. Alternate furrow irrigation, applying water to one of two continuous furrows, has been applied mainly in arid and semi-arid regions to conserve water and to increase water productivity in agricultural lands [10][11][12]. Drip irrigation can reduce the irrigation amount without reduction in crop yield and hence increase water use effi ciency by delivering water directly to the roots of the crop and reducing evapotranspiration and percolation.…”

Rice is a widely cultivated crop in China and needs a large quantity of water during its entire growth period. Many water-saving irrigation techniques have been developed and widely applied to conserve water in paddy fi elds in recent years. A controlled and mid-gathering irrigation (CMI) regime is one of them, of which the main feature is to maximize the use of rainwater different from the others. The objective of this study was to assess and verify the water conservation and nitrogen pollution reduction effects of CMI in comparison with a conventional irrigation (CVI) regime. Results showed that the CMI method had potential for water conservation by reducing total irrigation amount and irrigation frequency and making better utilization of rainwater during the rice growth stage. By making use of irrigation water more effi ciently, CMI showed higher irrigation water use effi ciency and rainfall use effi ciency. CMI can also reduce nitrogen pollution emitted to the water system by reducing the pollutant discharge rather than the pollutant concentration during a storm event. However, the irrigation regime's effect on pollutant loading reduction was not as signifi cant as fertilizer according to experiment results. Thus, the controlled and mid-gathering irrigation regime was favorable for water conservation and reducing emissions of non-point source pollution.

A field study was conducted to evaluate the effect of two‐dimensional infiltration on management of conventional furrow irrigation (CFI) and alternate furrow irrigation (AFI). For this purpose, 48 infiltration tests were carried out in CFI and AFI under two different irrigation intervals (4 and 9 days) with two different water heads (5 and 10 cm). The results indicated that under higher water head and lower initial water content, cumulative infiltration is increased by up to 102 and 62% in CFI and by up to 106 and 54% in AFI, respectively. Moreover, by increasing the water head, the lateral infiltration in CFI and AFI increased by 5 and 4.5 times, respectively. For a lower initial water content, lateral infiltration can increase by up to 96 and 53% in CFI and AFI, respectively. In all cases, cumulative and lateral infiltrations in AFI were greater than in CFI. Furthermore, the relative lateral infiltration in AFI was more than CFI. In both CFI and AFI, the relative lateral infiltration increased for increased water head and extended irrigation intervals. Application of AFI with higher water heads and extended irrigation intervals can lead to increased lateral infiltration and decreased deep percolation, which will ultimately result in improved irrigation efficiency.
