Plant Introduction Centre of Pakistan Agricultural Research Council carried out the research study at Malir and Gaddap Karachi. The area is being irrigated by the runoff collected from the catchment of Gaddap, which is stored in Thado-dam. Mostly the crops are lemon and Guava having fruits from May to July and the area under study was 3.65 hectors, the climate in this area is mild to humid and the rainfall range from (180 to 250 mm per year).

The fruit trees were planted at 12mx12m and 11mx11m under the drip irrigation system consisted of the water source, motor pump, main, sub main and lateral line, micro tubes and pressure gauge. The data was collected at the head, mid and tail of the alternate laterals in the command of each sub main. Drip Irrigation system The emitters flow rate was measured by graduated cylinder used to measure the volume collected for a given time with the help of stopwatch. Discharge uniformity was measured to find out evenly the water was distributed within the installation drip irrigation system. The discharge uniformity under different distances of hydrozones from water source on main line basis is 97%.
