ABSTRACT
The influence of growing conditions and planting dates on vegetative growth of Silvery was studied at Ornamental Horticulture Nursery, Department of Horticulture, The University of Agriculture, Peshawar Khyber Pakhtunkhwa, Pakistan, during January to September, 2011. Randomized Complete Block Design (RCBD) with split plots arrangement was used for the experiment. The experiment was replicated four times. The Silvery softwood cuttings were planted in two different growing conditions i.e. under plastic tunnels and open field growing conditions, on five different planting dates with the regular interval of 15 days such as January 15th, January 31st, February 15th, March 2nd and March 17th. The growing conditions were studied in main plots, while the planting dates were assigned to the sub plots. It was found that most parameters were non significantly influenced by growing conditions and planting dates. The experimental findings revealed that cuttings planted under plastic tunnels growing conditions showed less number of days to buds sprouting (17 days) and more sprouting percentage (96%), number of sprout plant-1 (6.45), sprout length (27.41 cm), sprout thickness (0.12 cm), number of leaves plant-1 (16.33) and plant survival percentage (81.72%). The more day to new bud sprout (24 days) and the minimum sprouting percentage (79%), number of sprout plant-1 (4.80), sprout length (23.96 cm), sprout thickness (0.07 cm), number of leaves plant-1 (12.88) and plant survival percentage (59.18%) were recorded in open field growing condition. In case of planting dates the highest sprouting percentage (96.3%), number of sprouts plant-1 (7.04), sprout length (32.52 cm), sprout thickness (0.13 cm), number of leaves sprout-1 (18.37) and plant survival percentage (91.25%) were recorded for cuttings planted on 17th March, 2011. March 17th plantation under plastic tunnels growing condition was recorded the best interaction between growing conditions and planting dates, which showed better results for most of the growth parameters. It is concluded from the present results that March plantation under plastic tunnels growing condition perform the best for vigorous growth of Silvery cuttings under the agro climatic condition of Peshawar, Pakistan.
