Abstract

Bougainvillea is one of the ornamental plants usually use for landscaping because of its colorful leaves and flowers. It is also used as a stabilizer and environmental preserver of pollution. This plant is propagated by cutting, however, there is a need to ensure easy growth of roots. Therefore, the purpose of this research was to determine the influence of stem cutting type and IBA concentration on vegetative growth of bougainvillea. The study was conducted in the experimental garden of the Faculty of Agriculture, UPN "Veteran” Yogyakarta, between October 2019 and January 2020 using a Randomized Completely Block Design (RCBD) with a factorial arrangement. The factors include the terminal, middle, and basal types of stem cutting while the IBA concentration was varied between 50, 100, 150 ppm and without IBA. The result showed 100 ppm IBA on the middle and basal type produced higher shoot number and shoot length of bougainvillea. The middle and basal type produced the best of percentage cutting to life, root number, length of longest root, and root volume. The giving IBA in cuttings produced the better root growth than without IBA.

Abstract

Inorganic fertilizers used continuously in tomato cultivation cause soil degradation which will affect the growth and yield of tomato plants. Efforts to maintain soil fertility include applying organic fertilizers and reducing inorganic fertilizers, one of which is vermicompost. The aim of the study was to obtain the best treatment combination from the administration of various doses of vermicompost and the time of pruning water shoots. The research was conducted from July to October 2022 in Kalasan, Yogyakarta. The research method was a field experiment using a factorial Complete Randomized Block Design. Factor I was the dosage of vermicompost: 5 tons/ha, 10 tons/ha, 15 tons/ha, and 20 tons/ha. Factor II was the time of pruning water shoots: 20 days after planting (DAP), 35 DAP and 50 DAP. The results showed that vermicompost 20 tons/ha by pruning water shoots at 20 DAP gave the best results on the number and weight of fruit per plant. The treatment of vermicompost at 20 tons/ha gave the best results on plant height and stem diameter, as well as pruning water shoots at 20 DAP.
