Abstract

The experiment “performance of different olive cultivars under time of grafting” was laid out inrandomized complete block design with two factors factorial arrangement replicated three times.Three olive cultivars, i.e., Kalamata, Arbequina and FS-17 were used as scion on wild olive rootstock with three different grafting times i.e. Early June, Mid July and late August. Differenttimes of grafting significantly affected all of the parameters studied, except number of leaves.Significant differences were observed among cultivars for all variables studied, except fornumber of sprouts per grafting. In case of time of grafting, maximum sprouting percentage(73.8%), number of sprouts (4.1), shoot length (12.23 cm), shoot diameter (2.56 mm), leaves pershoot (17.05) and minimum days to sprouting (26.6) were recorded in olive plants grafted inJuly. The plants grafted in June took higher days to sprout (32.7), minimum sprouting percentage(67.7%) and shoot diameter (1.97 mm), whereas plants grafted in August attained minimumshoot length (8.83cm). In case of performance of different cultivars, maximum sproutingpercentage (71.8%), shoot length (11.48cm), Leaves per shoot (17.43) and lower days tosprouting (28.5), and shoot diameter (2.06mm) were attained by cultivars Arbequina, whileKalamata showed lower sprouting percentage (62.7%), leaves per shoot (12.80) and maximumdays to sprouting (30.1). It is concluded that July is the optimum time for grafting of olivecultivars, specifically Arbequina.
