The above tables show as irrigation costs on different cultivations are always higher for drip-systems, which require more investments for the purchase of the equipment, labour costs, management, surveillance and dismantling of the eqipment, and in any case they force nearly same water and energy costs as for hose-reel irrigation machine.

The similar water and energy costs between the two irrigation systems is a confirmation of higher water consumption of drip-systems, also if they work at low pressures.

IRRIGATION COSTS The irrigation cost is the result of the sum of cost for equipments purchase, labour cost for installation, management and surveillance of equipments, and water cost, which includes energy cost too. The analisys of costs, made in the farms were we made the comparison between hose-reel irrigation machine and drip-system, evidenced that the irrigation costs of drip-systems are enormously higher than those of hose-reel irrigation machines, also with different farm management and water availability (see Table n°5)
