“…In 2014, it was enhanced to 86.1% under GCRPS sat and 90.1% under GCRPS 80% , which was similar to the value of 92.2% under TPRPS. Therefore, to use rainfall efficiently and keep the effect of increasing soil temperature under GCRPS, which was demonstrated to be very important for rice growth before max-tillering stage (Liu et al, 2013), it may be beneficial to maintain a transient water layer on the soil beds after the max-tillering stage rather than in the early growing season.…”

“…The experimental site was located in the Qinbashan Mountains with a northern subtropical monsoon climate condition. As one of the main crops in this region, rice often suffers from low temperatures during its early growing season and can face seasonal water scarcity in spite of a local annual average rainfall reaching 830 mm (Liu et al, 2013;Tao et al, 2015). For example, the average rainfall of about 100 mm during April and May (the early growing season of rice) from 2009 to 2014 is less than 20% of the rainfall throughout the growing season, representing less than half of the total water requirement for TPRPS.…”

“…Over the last decades, several innovative technologies have been developed to reduce water consumption for rice cultivation (Peng et al, 1999;Belder et al, 2004;Liu et al, 2005). The ground cover rice production system (GCRPS), proposed in 1980s (Lin et al, 2002), has been found to reduce water application, enhance soil temperature, inhibit weed growth, and increase rice production Liu et al, 2005Liu et al, , 2013Tao et al, 2006;Li et al, 2007;Qu et al, 2012) and is therefore regarded as one of the most promising watersaving technologies for rice (IRRI, 2011). The GCRPS is currently applied on more than 4 million ha in China (Tao et al, 2015).…”

s u m m a r yThe ground cover rice production system (GCRPS) offers a potentially water-saving alternative to the traditional paddy rice production system (TPRPS) by furrow irrigating mulched soil beds and maintaining soils under predominately unsaturated conditions. The guiding hypothesis of this study was that a GCRPS would decrease both physiological and non-physiological water consumption of rice compared to a TPRPS while either maintaining or enhancing production. This was tested in a two-year field experiment with three treatments (TPRPS, GCRPS sat keeping root zone average soil water content near saturated, and GCRPS 80% keeping root zone average soil water content as 80-100% of field water capacity) and a greenhouse experiment with four treatments (TPRPS, GCRPS sat , GCRPS fwc keeping root zone average soil water content close to field water capacity, and GCRPS 80% ). The water-saving characteristics of GCRPS were analyzed as a function of the measured soil water conditions, plant parameters regarding growth and production, and water input and consumption. In the field experiment, significant reduction in both physiological and non-physiological water consumption under GCRPS lead to savings in irrigation water of $61-84% and reduction in total input water of $35-47%. Compared to TPRPS, deep drainage was reduced $72-88%, evaporation was lessened $83-89% and transpiration was limited $6-10% under GCRPS. In addition to saving water, plant growth and grain yield were enhanced under GCRPS due to increased soil temperature in the root zone. Therefore, water use efficiencies (WUEs), based on transpiration, irrigation and total input water, were respectively improved as much as 27%, 609% and 110% under GCRPS. Increased yield attributed to up to $19%, decreased deep drainage accounted for $75%, decreased evaporation accounted for $14% and reduced transpiration for $5% of the enhancement in WUE of input water under GCRPS, while increased runoff and water storage had negative influence on WUE (À7.5 and À3.7%, respectively) for GCRPS compared to TPRPS. The greenhouse experiment validated the results obtained in the field by simplifying the non-physiological water consumption processes, and thus confirming the relative importance of physiological processes and increased WUE under GCRPS.

El uso eficiente del agua determina el futuro del cultivo de arroz en Colombia frente a los tratados de libre comercio, ya que es un factor que condiciona el área sembrada, el rendimiento de la cosecha y los costos de producción, además de su sostenibilidad en el tiempo. Por lo tanto, se presenta una revisión de las tecnologías desarrolladas a nivel mundial enfocadas al ahorro del agua en el cultivo de arroz en condiciones aeróbicas y anaeróbicas. Se resaltan tecnologías alternativas que superan al sistema convencional en rendimiento y en la cantidad de arroz cosechado por metro cúbico de agua invertido. En la reflexión para Colombia, se destacan aspectos importantes para la construcción de la agenda de investigación y la apropiación social de las tecnologías alternativas con miras a la optimización del recurso hídrico en el cultivo de arroz; se recomienda priorizar el arroz aeróbico y la medición efectiva del consumo de agua, indispensable para controlar su uso, planear, dirigir y entender cómo estas tecnologías alternativas conducen a la recuperación de la inversión de los agricultores y a la rentabilidad del cultivo.Palabras clave: Arroz, tecnologías, uso eficiente del agua, aeróbico, campo inundado. AbstractWater use efficiency, given that it conditions the sown areas, yield and production costs, as well as its sustainability, determines the future of rice production in Colombia against the FDA.

Seasonal drought and low temperatures strongly limit rice (Oryza sativa L.) grain yield in the hilly areas of Southwest China. An integrated rice management (IRM) system was developed, which integrates ridge cultivation with plastic mulching, furrow irrigation, and triangular transplanting. A field experiment was conducted from 2011 to 2015. The effects of IRM on grain yield, yield components, soil moisture content (θ), and soil temperature (Tsoil) were evaluated. Compared with traditional rice management (TRM), IRM significantly improved grain yield by 29.9%. Furthermore, the yield of IRM (8181−9267 kg ha−1, CV: 7.6%) remained relatively stable. The rice tiller of TRM was highly related to the accumulated rainfall during the rice tillering stage in drought years (2011 and 2014). The water retention capability of IRM decreased the influence of interannual rainfall on rice growth and grain yield. In 2015, the θ in the 0−20‐cm layer was higher than the threshold for rice root growth over the rice‐growing season. Compared with TRM, Tsoil of the 0−20‐cm layer in IRM was 4.7 °C higher during the early tillering stage. The >10 °C soil effective accumulated temperature in IRM was also higher, and the difference was highest at the maximum tillering stage. The warming effect of IRM, particularly during the tillering stage, stimulated early growth and stronger tillering. In summary, the water retention capacity and warming effect of IRM were key factors for the improvement of rice yield; most importantly, the yields were stabilized in both drought and rainy years.
