Abstract: An investigation was carried out at Rainfed Research Sub-station for Sub-tropical fruits, Raya, SKUAST- Jammu during the year 2017-18. The twelve year old plants were sprayed with GA3 (75 ppm), ethrel (150 ppm, 300 ppm and 450 ppm), KNO3(1.0 %, 2.0 % and 3.0 %) and K2SO4 (0.5 %, 1.0 % and 1.5 %) at two intervals viz., first spray was performed during first week of May 2017 and second spray after six weeks from first spray on growth and yield of Kinnow mandarin. The results revealed that application of 75 ppm GA3 showed superior results with respect in plant height (10.38 %), in plant spread (13.41 %), per cent increase in canopy volume (41.97 %), least fruit drop percentage (16.18 %), maximum number of fruits per tree (238.33) and yield (27.43 kg/tree) over control.
