Description Wheat production in Morocco is crucial for economy
and food security. However, wheat production is difficult
because the semi-arid climate causes very variable wheat
yields. To solve this issue, we need better prediction of the
impact of drought on wheat yields to adapt cropping management
to the semi-arid climate. Here, we adapted the models
WOFOST and CropSyst to agro-climatic conditions in Morocco.
Six soft and durum wheat varieties were grown during
the 2011–2012 and 2012–2013 growing seasons in the experimental
sites of Sidi El Aydi, Khemis Zemamra and
Marchouch. Drip irrigation and rainfed treatments were arranged
in a randomised-block design with three replicates. We
determined the phenological stages of emergence, tillering,
stem elongation, flowering and maturity. We measured aboveground
biomass six times along the season. These data were
used to adapt WOFOST and CropSyst to local conditions. Our
results show that both models achieved good estimations, with
R2 always higher than 0.91, and positive values for Nash and
Sutcliffe modelling efficiencies. Results of spatially distributed
simulations were then analysed for the whole country in
terms of different response to drought.
