Yields were simulated to decrease – very moderately though – atonly one site, Spitamen (Tajikistan). Spitamen was among the siteswith the relatively highest increase in annual rainfall (∼7% on aver-age), which resulted in an increased loss of nitrate out of the rootingzone and a subsequent slight increase in N-stress under the givensoil (N-levels) and (poor) management conditions. These resultshowever have to be considered with care, as simulation of nitratemovement in soils can only roughly approximate reality, when realobservation for an in-depth site/soil specific model calibration areabsent as was the case for Spitamen. To provide a firmer answer,more detailed field studies and subsequent model simulations needto be carried out. Similar is true for the precise simulation of theimpact soil salinity – historically as well as under CC – which wasshown to influence yields at Akaltyn site.
