  Rosa centifolia and Rosa damascena are famous essential oil producing Rosa species in Pakistan. Pruning is important and common practice used to enhance flowering. In this experiment effect of different pruning types was observed on flowering of above mentioned Rosa species grown at Rosa project, University of Agriculture, Faisalabad, Pakistan. Light (15 cm), medium (10 cm) and severe (5 cm) pruning was practiced on the plants in the month of November, 2013. The data of number of branches, flower shoot length, 100 petals weight, flower weight, number of petal per flower, weight of petals per flower, number of buds per plant, number of cut flowers per plant, total number of flowers per plant was recorded. Both the species produced similar results except 100 petals weight, which was 5.34 g in R. centifolia and 5.21 g in R. damascena. Severe pruning produced maximum flower shoot length (2.11 cm), flower weight (2.99 g), number of petal (60.11) and weight of petals per flower (2.09 g), while medium pruning produced maximum number of branches (33.70), number of buds per plant (284.17), number of cut flowers (251.56) and total number of flowers per plant (541.17). Unpruned plants produced minimum result in all parameters, which proved pruning effective for increasing yield of R. centifolia and R. damascena. Medium pruning enhances flowering in R. centifolia and R. damascena, which will be helpful for their essential oil extraction business in Pakistan.

  Background and Objective: Ravenea palm (Ravenea rivularis) is the most popular grown interior potted plant. Present study was carried out to assess the effect of different potting substrates in various compositions on growth and development of Ravenea plants. Materials and Methods: In total, ten treatment combinations were used to compare with control treatment (garden soil) and treatment was consisted of 16 plants with four replications. Various potting substrates: Garden soil, silt, farmyard manure, peat moss, leaf compost and coconut compost in various combinations were added. The experiment was carried out in Completely Randomized Design (CRD). The collected data for plant growth and development were subjected to Duncan’s Multiple Range (DMR) test whereas for chemical and physical characteristics of potting substrate and means was compared. Results: The results depicted that the T10 that is the combination of farmyard manure, silt, coconut compost, peat moss and leaf compost (1:1:1:1:1) exhibited best results for the growth and production of potted Ravenea plants. The treatment T10 substrate is considered excellent due to its density, saturation percentage, structure, texture, consistency and Organic Matter (OM) as well as nitrogen, phosphorus and potassium concentration. Conclusion: It can be concluded that to get quality pot production a mixture of substrates proved to be best as it delivers a combination of properties and nutrients. The new potting mix will provide a stable, organic, sustainable, environmental friendly and cost effective alternatives to nurserymen.
