Modelling the effects of soil and water management practices on the water balance and performance of rice

Climate Change and its Impact on Rice Yield

“…The correlation was found weak because the monsoon rain amount was quite sufficient for the required soil moisture to the crop. This finding agrees with results from other recent experiments on water saving technologies (WSTs), which have demonstrated that rice doesn't need continuous submergence for high yield (Belder et at.,2004, Tuong and Bhuiyan, 1999, Singh et al, 2001, Anbumozhi et al,1998, Zeng et al,2003, Dunn and Gaydon, 2011, Tuong and Boman, 2003, Yang et al, 2012, Mahajan et al, 2009, Choudhury et al, 2007, Arora, 2006, Pirmoradian et al, 2004, Bouman and Tuong, 2000, Dawe, 2005, Tabbal et al, 2002, Humphreys, E.,2005.…”

Analysis of Temporal Variation of Soil Salinity during the Growing Season in a Flooded Rice Field of Thessaloniki Plain-Greece

“…The development and application of models which describe salinity components (anions-cations dynamics) in rice fields, remain a great challenge even though many have been developed to describe the water, nutrients (nitrogen, phosphorus) and pesticides transport under these conditions [12,[25][26][27][28][29][30][31][32][33][34][35][36][37]. Methods based on water budget approaches in combination with the monitoring of salinity are common tools to analyze soil salinity components in rice fields [38][39][40][41].…”

Rice performance, water and nitrogen efficiency in different irrigation regimes in tropical lowland

“…The common factor between these studies was they took place on Alfisols and/or puddled soils. In such type of soil, the water percolation rate is usually limited (Belder et al, 2007;Singh et al, 2001), and its submergence results in oxidizing zones just restricted to water/air interface and rhizosphere (Atulba et al, 2015;. The majority part of soil bulk remains anoxic, and nitrification process is disadvantaged.…”

“…The experimental site of this study has a fairly high saturated hydraulic conductivity (ksat = 1.35 and 0.16 m d -1 in A and B plinthic horizons, respectively), compared to others lowland rice production areas. Usually it is in a range from 0.8 to 0.0003 m d -1 in Philippines, India, China, California and Uzbekistan Liang et al, 2014;Singh et al, 2001;Wopereis et al, 1994). The micro-structure of this soil has a coarse sand size and it provides low bulk density and prominent macroporosity, resulting in a high hydraulic conductivity (Ks) (Buol and Eswaran, 1999).…”

“…However, the penalization in crop productivity is also reported, and depreciation between 0% and 38% leads adoption to proceed with caution and require site-specific adaptation. The lower productivity is attributed to the direct consequence of inadequate water supply to meet ET Singh et al, 2001), to genotypes not adapted to soil water tension around field capacity , or the indirect influence of irrigation on the lower availability of nitrogen in the soil Kadiyala et al, 2015;.…”
