| Abstract | ||||
| Mobile drip irrigation system ''MDIS'' consists of on/in-line drip hoses at different spaced between lines being dragged through various crops by a center pivot or lateral move irrigation system. Technology of MDIS combines the efficiency of surface drip irrigation (95%) with the flexibility and economics of center pivot and lateral move irrigation systems. While conventional center pivot and lateral move irrigation water application packages are efficient and provide many different options for distributing water. MDIS technology increased system application efficiency through precision drip irrigation with the slow methodical release of water and nutrients directly to the soil area for optimal plant growth. A mobile drip irrigation system ''MDIS'' was designed using the classic dripping irrigation materials and determine the best system speed which gives best witting front advance in horizontal, vertical and diagonal directions in the loamy sand soil. The MDIS was evaluated at four system speeds of 5, 10, 15, and 20 and three types of drip tubes of . The results showed that the classification of all used drip tubes were fully pressure compensating and the application efficiency of MDIS was higher than 82%. Also, results obtained the mathematical relationships which describe wetting front advance in horizontal ''H'', vertical ''V'', and diagonal ''D'' directions in loamy sand soil. | ||||
