ABSTRACT
To study the effect of various concentrations [0 ppm (control), 1000 ppm, 2000 ppm and 3000 ppm] of Naphthalene Acetic Acid (NAA) on rooting of various olive varieties (Hamdi, Nocellara and Sevallino) an experiment was conducted at Agricultural Research Institute (ARI) Tarnab, Peshawar during 2016. The trial was performed using two factorial RCBD. Cuttings were collected from mature olive orchard. The cuttings were treated for ten seconds in required concentration of NAA solutions. According to the experimental results, minimum days to root appearance (54.58), maximum root diameter (0.18 cm), maximum leaves shoot-1 (15.67) were noted in Nocellara variety, lengthy root (4.30 cm) was found in Sevallino variety and maximum survival (47.6%) was observed in Hamdi variety, while minimum days to root appearance (46.33), number of days to bud sprout (34.89), maximum roots cutting-1 (5.78), root length (5.36 cm), shoot length (16.66 cm), shoot diameter (0.30cm), number of leaves shoot-1 (15.78), number of branches cutting-1 (4.89) and plant survival percentage (50.36%) were noted in cuttings treated with 3000 ppm of NAA solution. Regarding interaction both varieties and NAA concentrations showed significant results for all variables except days to root appearance, length of shoot (cm), shoot diameter (cm), branches cutting-1, and plant survival (%). It was concluded that the variety, Nocellara treated with 3000 ppm of NAA solution showed best results on growth variables.
