The research was conducted at the Research Field of Lampung State Polytechnic, Bandar Lampung. The objectives of the research were (1) To design and construct the drip irrigation type orifice without pump for salad (Lactuca sativa L.) with hydrophonic system on cropshelf, and (2) To test irrigation efficiencies performance of the drip irrigation  type orifice without pump.  The result of the research showed that the drip irrigation type orifice without pump given distribution efficiency of water nutrition by 87.26%, water nutrition use efficeiency of 75.61%, and  salad production average of 130.31 g/tanaman, and water nutrition productivity of 2.44 kg/m3.  Salad  production dan water nutrition productivity average by  the drip irrigation type orifice without pump was higher compared to traditional water nutrition application.    Keywords: The drip irrigation type orifice, water nutrition, efficiency, and  Lactuca    sativa L.
