The developed implement was operated by the mini-tractor using three-point hitch, it performs both the operations of installation and retrieval of drip line. The performance was evaluated on the basis of various field parameters, operating parameters and performance parameters. The experiment was carried out in F-RBD design having two factors and four replications with three different levels of each factor. The factors namely spool rotation (35-53, 53-71 and 71-89 rpm) and forward speed (2.03.0, 3.0-4.0 and 4.0-5.0 kmph) were taken for an experiment. It was observed that the time required for installation and retrieval of drip was 1.0 and 0.94 s/m respectively at 71-89 rpm of spool rotation and 4-5 kmph of forward speed. The fuel consumption in installation and retrieval operations was 4.0 and 4.23 lit/ha respectively at 71-89 rpm of spool rotation and 4-5 kmph of forward speed. The theoretical field capacity, actual field capacity and efficiency of installation were 1.35 ha/h, 0.85 ha/h and 63.68 per cent and the same for retrieval were 1.35 ha/h, 0.90 ha/h and 66.66 per cent respectively.
