Abstract
This paper develops a dynamic programming optimisation model, that consider
the competition of crops in a season, both for irrigation water and cultivated area.
Decision variables are the cultivated area and water allocated to each crop. The
objective function of the model is based on crop-water production functions,
production costs and crop prices. The model is solved using CSUDP generalised
dynamic programming package for conditions existing in Northern Tunisia
where a large fraction of the irrigation water is stored in the reservoir mainly
during the winter period. The model gives the optimal distribution of area and
water to each crop and profit. Results indicate that the model can be a valuable
tool in determining seasonal croppin
