Abstract: The kiwifruit (Actinidia deliciosa) is an edible berry of a woody vine in the genus of Actinidia. It is grown successfully in north western Himalayan states of India. There is a potential scope to grow in Darjeeling hills of West Bengal. Stem cutting is the onlymethod of vegetative propagation which is commercially used. An experiment was conducted at the Experimental farm of Darjeeling Krishi Vigyan Kendra, Uttar Banga Krishi Viswavidyalaya on Kiwifruit cv. Hayward having sixteen treatment combinations with three factors (girdling, etiolation and growth promoter) using factorial randomized block design. Girdling on etiolated shoot with application of IBA @5000 ppm (T16) showed better response for total number of days taken for sprouting (77 days), length of the sprout (2.07 cm), sprouting percentage (68.33%), rooting percentage (68.33 %), days taken for rooting (87.33 days), longest root length (5.90 cm), survival percentage (64.53 %), mortality rate (46.02 %).
