#ASSENG APSIM RUE WHEAT WINDOWS#
We explore in this study the potential changes in spring wheat yields at Swift Current and Melfort, Canada, for different sowing windows under projected climate scenarios (i.e. White, J.W., Herndl, M., Hunt, L.A., Payne, T.S., Hoogenboom, G., 2008. Assessing the impacts of climate variability on agricultural productivity at regional, national or global scale is essential for defining adaptation and mitigation strategies.

#ASSENG APSIM RUE WHEAT SIMULATOR#
Understanding options for agricultural production. The Agricultural Production Systems Simulator (APSIM) suite of models was used to predict dynamics in water and nitrogen in soil, as well as the growth and yield of sequential crops of wheat and barley in pasturewheatbarley rotations, between 19 at Roseworthy, South Australia. CERES-Wheat: A user oriented wheat yield model. Photoperiod and vernalization effect on anthesis date in winter-sown spring wheat regions. Ottman, M.J., Anthony Hunt, L., White, J.W., 2013.
A crop simulation model (apsimnwheat) was used to evaluate the role of these traits in improving potential yield under a range of environmental conditions. Cropsim-Wheat: A model describing the growth and development of wheat. Physiological traits such as increased kernel number, early flowering, and an increased rate and duration of kernel filling, are thought to increase the potential yield of wheat in certain environments. Uncertainty in simulating wheat yields under climate change. Characterizing local variability in crop phenology (Ottman et al., 2013)Īsseng, S., Ewert, F., Rosenzweig, C., Jones, J.W., Hatfield, J.L., Ruane, A.C., Boote, K.J., Thorburn, P.J., Rotter, R.P., Cammarano, D., Brisson, N., Basso, B., Martre, P., Aggarwal, P.K., Angulo, C., Bertuzzi, P., Biernath, C., Challinor, A.J., Doltra, J., Gayler, S., Goldberg, R., Grant, R., Heng, L., Hooker, J., Hunt, L.A., Ingwersen, J., Izaurralde, R.C., Kersebaum, K.C., Muller, C., Naresh Kumar, S., Nendel, C., O/’Leary, G., Olesen, J.E., Osborne, T.M., Palosuo, T., Priesack, E., Ripoche, D., Semenov, M.A., Shcherbak, I., Steduto, P., Stockle, C., Stratonovitch, P., Streck, T., Supit, I., Tao, F., Travasso, M., Waha, K., Wallach, D., White, J.W., Williams, J.R., Wolf, J., 2013.Gene-based modeling (White et al., 2008).AgMIP wheat model intercomparisons (Asseng et al., 2013).Minor modifications were made to phenology routines to avoid unrealistic behavior under certain, extreme conditions.Įxamples of applications of CERES-Wheat include: Recent development work on CERES-Wheat has largely focused on ensuring that, so far as possible, model parameters of CERES-Wheat and CROPSIM-Wheat (Hunt and Pararajasingham, 1995) are defined in a comparable manner. (1998) provides additional information on how growth, development and yield are simulated.
The temperature effects includes a response to vernalizing temperatures, which allows distinguishing among the phenology of spring, facultative and winter wheats. Development is potentially affected both by temperature and daylength. Conclusions Asseng, Foster & Turner 2011 The impact of temperature variability on wheat yields. Growth is modeled via a radiation use efficiency approach. events can cause wheat yield reductions of 50 Future global warming will further increase temperature-effected yield reductions Temperature is a poorly-recognised threat to Global Food Security. Featured journals include Journal of East African Natural History, Annales Zoologici, Journal of Ethnobiology, Ursus and more.Bread and durum wheat may be simulated using the CERES-Wheat model, whose origins trace back to modeling efforts of Joe Ritchie and colleagues in the 1970s (Ritchie et al., 1984). We are pleased to share a selection of top and trending articles published in BioOne journals that cover all areas of the biological, environmental, and ecological sciences.
