Title: Effect of Different Potting Media on Growth and Flowering of Bougainvilleatorch glow
Author: Musa, Samah Osman Mohamed
Abstract: This experiment was conducted at the Nursery of the Department of Horticulture-Faculty of Agriculture, University of Khartoum, during May - October 2015. The objective of the experiment was to study the effect of mixing silt, field soil with compost and mangoleaf mould at different ratios on growth and flowering of bougainvillea (Bougainvillea torch glow). Bougainvillea transplants were potted into polyethylene bags (40 cm diameter and 50 cm height) containing the following media: silt 100%, silt 75% + compost 25%, silt 50% + compost 50%, silt 75% + leaf mould 25%, silt 50% + leaf mould 50%, field soil 100%, field soil 75% + compost 25%, field soil 50% + compost 50%, field soil 75% + leaf mould 25%, field soil 50% + leaf mould 50%. The ten treatments were arranged in a randomized complete block design with three replications. Experimental unit consisted of three plants. Statistical analysis was done using statistical package for social science (SPSS) program and mean separation was done using Duncan’s multiple range tests at 5% level of significance. Data were collected on plant height, number of leaves per plant, number of branches per plant, stem diameter, plant fresh and dry weights, and number of inflorescences per plant. The results revealed that the greatest values of number of leaves and branches were associated with silt 75% + leaf mould 25%, the greatest values of plant height and fresh weight were associated with silt 75% + compost 25%, the greatest values of stem diameter, dry weight and number of inflorescences were associated with silt 50% + compost 50%. The lowest values of all parameters except number of branches were associated with field soil 50% + leaf mould 50%. The lowest value of number of branches was associated with field soil 50% +compost 50%. As a general recommendion it can be stated that adding compost at 50% or completely decomposed mangos leaf mould at 25% to silt or field soil can be considered an ideal potting media for growth and flowering of bougainvillea.
