Abstract:

The study was undertaken in Southern parts of Karnataka to evaluate and to assess the design and performance of the different make drip irrigation systems in Greenhouses. Information about farmers and other details were collected from different dealers of respective company makes. The three greenhouses from each companies, which were selected for the study. The results on the design indicated that all the greenhouses having good operating system, but the six of them were not capable to operate the system results in poor performance. The hydraulic parameters such as coefficient of manufacturer variation, emission uniformity, uniformity coefficient, application efficiency and distribution efficiency were found to be excellent at both 0.75 and 1.00 kg/cm2 operating pressure for all the irrigation system of different makes. However, the emitter flow variation observed to be acceptable only for company A, C and E at 1.00 kg/cm2 operating pressure and it was not acceptable at 0.75 kg/cm2 for all the irrigation makes. The value of emitter exponent and discharge coefficient varied between 0.37 to 0.79 and 2.72 to 3.34 respectively, which indicates the flow is almost turbulent. Hence all company drippers were found to be in the range of non-pressure compensating. The company A having better hydraulic efficiency followed by company B, C, D, and E. The cost of installation per acre for all the systems was found to be in the range of Rs. 45000/- to 52000/-.
