To simulate crop growth and crop yield, we used the auto-fertilization and autoirrigation options of SWAT, assuming that there is no water and fertilizer stress in the production of irrigated wheat.  ...  Data on annual planting and harvesting dates were in particular lacking. We only had data on long-term average dates.  ...  Also, the data on planting and harvesting dates and fertilizer used in this study represented long-term averages over the respective province while MOJA used finer resolution sub-provincial information  ... 


Thus, errors will arise if temporal variations are ignored: for example by using monthly, annual, or long-term average data.  ...  This information is needed for improving understanding of the effects of soil management or land use on soil profile hydrology.  ...  Appendix Appendix 2: An example of Land use and hydrological and pedological parameters inputs in IDRAGRA model  ...
