Starting from areas where irrigation is dependent on power: electric or diesel, High Efficiency Irrigation Systems (HEIS) not only cut the energy costs to half but also help increase the area (double) with the expense of same amount as with flood irrigation.
Capital investment is high but one can gradually bring more area under HEIS. If the system life is a minimal 10 years, one can divide the cost by ten and add as an input cost per season/ crop or annum. For example, if the cost is $500, then per annum cost would be merely $50!
