Subject Water scarcity, discharge, pressure head, uniformity, trickle irrigation and performance.
Description Irrigation using drippers is often considered the most efficient method in terms of both water use and labour, but because it is complex, it must be designed, installed, and maintained correctly. Keeping in view this fact trickle irrigation system using locally produced materials was designed and installed on an area of 1.2 acres for citrus orchard at the field station of water resources research institute, NARC Islamabad, Pakistan. The cost of this indigenized trickle irrigation system was Rs. 104900/acre for orchards. The system was evaluated for its hydraulic performance. Results of the study revealed that the discharge of the micro tube-emitter varied from 15.67 to 8.67 l/h under the pressure head of 10.56 to 7 m. The water application uniformity was found to be above 80% which describes that the drip irrigation was designed on proper scale and dimensions. Statistical analysis of all the research parameters i.e. water application uniformity, discharge and pressure are well elaborated, which showed that water application uniformity was more than 80 % which is an indicator of good performance of the system as recommended by Jensen. Further more, irrigation scheduling was also carried out for citrus orchard using climatic data of the project site.
