Given that the optimal sowing rate and inter-row spacing of Italian ryegrass raised for seed
have not been determined, the objective of this research was to assess the effect of crop
density on biomass and seed yields under different climate conditions, applying the AquaCrop
model. The data came from experiments conducted under moderate continental climate
conditions at Stitar (Serbia) and Mediterranean climate conditions at Cukurova (Turkey). At
Stitar, there were three different inter-row spacings (high (Sd), medium (Sm), and low (Sw) crop
densities), while at Cukurova there was only high crop density (Sn). In the calibration process,
the initial canopy cover, canopy expansion and maximal canopy cover were adapted to each crop
density, while the other conservative parameters were adjusted to correspond to all climate
conditions. Calibration results showed a very good match between measured and simulated
seed yields; the values of the coefficient of determination (0.922). Th...e biomass simulationwas very good for Cukurova (R2=0.97), but somewhat poorer for Stitar (R2=0.72). Other
statistical indicators were high such as Willmott index of agreement of both the calibrated and
validated data sets, for both study areas >0.916 and normalized root mean square error
(NRMSE) in the range from 9%–18%. The AquaCrop model was found to be more reliable
for Italian ryegrass biomass and seed yield predictions under mild winter climate conditions,
with adequate water supply, compared to moderate climate and water shortage conditions.
