Water management of crops to maximize the profit.

The objective this paper is, present schedule irrigation to maximize the profit in the irrigation farms under different conditions of available irrigation water volume. For each crop and different irrigation scenarios with connection to Aqua crop model, economic productivity of each crop under different deficit irrigation was calculated and its maximum was determined. The results showed when year is normal and water allocation to network equals to the long time average (option ۱۰۰%), the largest area is allocated to wheat cultivation (۱۰۷۴۰) and dry land (rain fed) is the least, if ۷۰% the long term annual average value is met, area under wheat cultivation will be ۳۰۰۰ hectares and approximately ۵۰۰۰ hectares of network must inevitably have managed rained and dry land.
