Comparative effects of drip and micro sprinkler systems under kinnow+kinnow and kinnow+poplar silvi-horti system were studied under sub tropical climate. Drip system of irrigation was found promising in maintaining better growth of kinnow plants. Kinnow+Poplar system of plantation was found superior over kinnow+kinnow system of plantation under drip irrigation system. Under this system (kinnow+poplar) of plantation, values of plant height at 70% ETC were 2.55 m, canopy volume 23.51 m 3, rootstock girth 11.13 cm, scion girth 10.76 cm, and leaf area were 16.07 cm 2. Of course, values for all these traits were higher at 100% ETc under kinnow+kinnow system of plantation over kinnow+poplar system of plantation under drip system but these were at par with each other. Irrigation of kinnow orchards at 100% ETc was found better irrespective of the systems of irrigation.
