Produktbeschreibung
Center pivot modification depends on replacing the sprinkler head (sprayers) by Polyethylene hoses ending by nozzles. The main objectives of this study are to modify pivot irrigation system to be more suitable to irrigate trees, and other crops under special conditions and to evaluate the modification system. The obtained results, High uniformity coefficient of modified pivot is up to 90% and TDH is 1.5 bar, Energy requirements for the modified pivot is lower than the energy requirement at pivot, its lower with (26% - 80.3%). The energy cost for modified pivot was lower than the sprinkler pivot by (81.25%), the cost of one m3 of water in LE for modified pivot was lower than sprinkler by (62.9 %), and finally, cost of the unit production unit (LE/kg) for modified pivot was lower than the sprinkler pivot by (23 %). Flexibility of modified pivot to irrigate shrubs, small trees, and plants which sensitive to water with any fungal disease or flowers fall.
