“…Regarding just transpiration there is little published information. Relative to TPRPS, significant limitation on leaf stomatal conductance has been observed under GCRPS due to drought stress Zhang et al, 2008Zhang et al, , 2009). In contrast, leaf area under GCRPS has been found to be greatly enlarged as a result of increased soil temperature (Tao et al, 2006;Xu et al, 2007;Qu et al, 2012).…”

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.

“…Recent literature supports the results of our studies. The results of a study indicated that growing rice under non-flooded aerobic conditions reduced the milling, cooking quality and appearance of rice grains in comparison with conventionally flooded rice (Zhang et al, 2008). However, straw mulch application improved the rice grain quality including grain filling, milling, appearance and cooking (Zhang et al, 2008).…”

“…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).…”

“…Importantly, these rice cultivation systems lack a standing layer of water compared with the conventional method (Nie et al, 2012). Although water inputs are lower for AR and AWD, however, higher evaporative moisture losses in these systems may adversely affect the rice crop growth and produce's quality (Zhang et al, 2008;Pandey et al, 2014). This situation is further worsened under the warmest summer prevalent in many of the rice growing areas of the world.…”

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.

“…High temperature affects cellular and developmental processes leading to reduced fertility and grain quality [4]. Decreased grain weight, reduced grain filling, higher percentage of white chalky rice and milky white rice are common effects of high temperature exposure during the ripening stage in rice [5]- [7]. Poor threshing, drying and milling methods may also cause fissures thus leading to high broken fractions.…”

In order to develop simple and adaptable measures to reduce the impact of changing climatic conditions and poor postharvest practices on grain quality, data on temperature and postharvest practices were collected and correlated with physical grain quality parameters for 3 rice development hubs (Ndop, Lagdo and Mbam) in Cameroon. Inter-annual variations in temperature and thermal amplitudes were the highest in Ndop followed by Mbam and the least in Lagdo. When the same rice variety was grown in the hubs and milled with a laboratory hand dehusker, the mean chalky score was highest in Ndop (18%) and least in Mbam (11%). In addition, Ndop recorded higher grain fissures and broken fractions compared to Mbam or Lagdo. Positive correlations were observed between thermal amplitudes, grain fissures and the proportion of broken fractions. However, rice milled using commercial mills located in the hubs recorded the highest broken fractions in Mbam (54% -63%), followed by Lagdo (43% -52%) and the least in Ndop (35% -38%). The type of mills in the hubs was responsible for these differences as Mbam had only Engelberg types mills that recorded higher broken fractions than in Ndop where only rubber roll mills were present (P < 0.05). Lagdo had a mixture of Engelberg and rubber roll mills and recorded intermediate broken fractions. Proper parboiling, recovery and processing of poorly filled and immature grains during parboiling and processing of low-grade and fine broken rice into product generally accepted by the local population were demonstrated as simple adaptation strategies to mitigate S. A. Ndindeng et al. 179the adverse effects of changing climatic conditions and poor postharvest practices on the physical quality of rice especially in sub-Saharan African countries.
