Abstract: In kiwi variety ‘Hayward’, softwood, hardwood and semi-hardwood cuttings were prepared during different months (January - December) in two years. The cuttings were treated uniformly with IBA 300 PPM and planted in the poly bag (1:1:1 peat: sand: FYM). The observations on days to 50% sprouting, number of roots, root length (cm), shoot length (cm) and survival percentage were recorded. Based on the pooled data of two years in softwood cuttings, 50% sprouting was earlier in cuttings prepared during May (39.55). Semi-hard wood cuttings prepared in April and May had taken 37.10 and 38.17 days for 50% sprouting. Hardwood cuttings had lower days for 50% sprouting (43.43) in April followed by May (46.95). The cuttings viz., semi hardwood, hard wood and softwood prepared during March month recorded significantly more number of roots (7.18, 8.42, 5.96). Higher root length was observed in softwood cuttings (10.49 cm, May), semi- hard wood cuttings (23.06 cm, June) and hard wood cuttings (9.01 cm, January). The longest shoots were observed in all three groups of cuttings prepared in March (7.63 cm, 9.92 cm, 6.12 cm). Among the three types of cutting semi-hard wood cuttings prepared in June, July (63.36%, 62.19%) had more survival percentage. Among In this experiment it was observed that semi-hardwood cuttings recorded higher vales for number of roots (8.42), root length (23.06), shoot length (10.48 cm), survival percentage (63.36%) and earlier days for 50% sprouting (37.10).
