To be aware about the potential benefits of agricultural decision modelling tools, being able to identify which agricultural management options should be change and how to optimise management and reduce climate risk of local agricultural production. iv. To have available data for the training course and for the potential conducting the SSA pilot assessments (crop growth and yields, meteorological variables, soil properties, irrigation and crop management scheduling, etc).

WOFOST uses the SUCROS approach for potential production conditions. WOFOST permits dynamic simulation of phenological development from emergence till maturity on the basis of crop genetic properties and environmental conditions. The cultivar- 24 Angel Utset Suastegui specific values of thermal time assimilate conversion coefficients, maximum rooting depth, daily root development rate and partitioning fractions are important inputs. Dry matter accumulation is estimated by the rate of gross CO2 assimilation of the canopy.

1978) root water-uptake model has the advantage that not only considers the crop transpiration reduction due to lower soil-water contents, but also takes in account the negative effect of water excess in the soil root zone. Utset et al. (2000) showed that the Feddes et al. (1978) model fits better to actual data, obtained in tropical conditions, than the model provided by Van Genuchten et al. (1987). , 2006). For salinity stress the response function of Maas and Hoffman (1977) is used in SWAP (Van Dam, 2000), as this function has been calibrated for many crops.
