“…The WP IR s in our experiments are close to a value (0.67 kg/m 3 ) reported by Ginigaddara and Ranamukhaarachchi (2009) in Thailand for DSR with one week irrigation, followed by three weeks without irrigation. Ye et al (2013) reported that the WP IR s of intermittently irrigated TPR in the Taihu Lake Basin were between 0.48 and 1.06 kg/m 3 for different fertilizer managements, with average values of 0.88 and 0.77 kg/m 3 during the 2010 and 2011 seasons, respectively. The WP ET s in our experiments fall in the range of globally measured values for rice (0.6-1.6 kg/m 3 ), and are higher than the average value (1.09 kg/m 3 ) (Zwart and Bastiaanssen, 2004) but slightly lower than the median value of 1.52 kg/m 3 (ranging from 0.89-2.03 kg/m 3 ) reported by Roost et al (2008) for TPR of the Zhanghe Irrigation District in Central China.…”

a b s t r a c tIn the recent decade, increasing costs of labor, water, and fertilizers around the world led to a change in the method of crop establishment from traditional transplanted rice (TPR) to direct-seeded rice (DSR) and to a substantial rise in the DSR-managed area. Since water management in areas with DSR is quite different from those with TPR, vertical water movement and water and nutrient losses during the crop season may be different as well. Water flow and water losses in a DSR field in the Taihu Lake Basin of east China were monitored and evaluated using Hydrus-1D during two seasons with different rainfalls and irrigation managements.

“…Thus, the optimal water and N application measures identified here cannot be applied together directly. Numerous studies have identified that there exist coupling effects of water-fertilizer management on crop yield, as well as water and fertilizer use efficiency [38][39][40]. Further research is needed to explore a reasonable co-allocation of water and fertilizer application in the wheat-maize rotation system, which can reduce the crop water footprint while maintaining the crop yields.…”

Abstract:Beijing is one of the most water-stressed regions in the world. Reducing agricultural water use has long been the basis of local policy for sustainable water use. In this article, the potential to reduce the life cycle (cradle to gate) water footprints of wheat and maize that contribute to 94% of the local cereal production was assessed. Following ISO 14046, consumptive and degradative water use for the wheat-maize rotation system was modeled under different irrigation and nitrogen (N) application options. Reducing irrigation water volume by 33.3% compared to current practice did not cause a significant yield decline, but the water scarcity footprint and water eutrophication footprint were decreased by 27.5% and 23.9%, respectively. Similarly, reducing the N application rate by 33.3% from current practice did not cause a significant yield decline, but led to a 52.3% reduction in water eutrophication footprint while maintaining a similar water scarcity footprint. These results demonstrate that improving water and fertilizer management has great potential for reducing the crop water footprints at the farm scale. This situation in Beijing is likely to be representative of the challenge facing many of the water-stressed regions in China, where a sustainable means of agricultural production must be found.

“…Growing rice under water saving systems such as alternate wetting and drying (AWD) and aerobic rice (AR) may decrease grain quality owing to quick moisture loss and resultant water stress (Dingkuhn and Gal, 1996;Zhang et al, 2008). However, growing rice under AWD and AR is inevitable in the wake of worldwide water shortages (Rejesus et al, 2011;Nie et al, 2012;Price et al, 2013;Ye et al, 2013). Nevertheless, the quick moisture loss from the rice fields sown by AR and AWD methods can be avoided applying mulches .…”

“…Energy and water are significantly saved under the water saving rice cultivation systems. Aerobic rice cultivation system (AR) and alternate wetting and drying (AWD) are the most important water saving rice cultivation methods which are under development throughout the world's important rice growing areas (Jabran et al, 2012b;Nie et al, 2012;Ye et al, 2013). Importantly, these rice cultivation systems lack a standing layer of water compared with the conventional method (Nie et al, 2012).…”

To cite this paper: Jabran, K., E. Ullah and N. Akbar, 2015. Mulching improves crop growth, grain length, head rice and milling recovery of basmati rice grown in water-saving production systems. AbstractWater saving rice cultivation is indispensable in the wake of severe water shortage. Application of mulches can increase the water retention in water-saving rice; however, the effect of mulches on the growth and quality of rice are desired to be investigated. Hence, two years studies were conducted to evaluate the effect of plastic and straw mulch on crop growth, grain quality and recovery of fine rice. Water saving rice was grown under aerobic (AR) and alternate wetting and drying (AWD) conditions with application of plastic and straw mulch (5 t ha -1). Plots without mulch were maintained in both the water saving systems for comparison. Mulches significantly improved the growth of rice crop in terms of leaf area index, crop growth rate, leaf area duration and dry matter accumulation of rice compared with the no mulch. Similarly, the rice grain quality was also significantly improved by the mulch application. Mulch application increased the brown and white rice length, brown and white rice recovery percentage. The plastic mulch was more effective than straw mulch in improving the growth and grain quality of rice under AWD and AR. AWD was more effective in improving the rice grain quality compared with the AR. In crux, either of the plastic or straw mulch can be applied in fine grain basmati rice fields in order to improve the crop growth and grain quality. The effectiveness of plastic mulch surpasses the efficiency of straw mulch.
