Abstract

Seeding media have a large role in helping to accelerate germination and seed will have a different response to certain media. Seeding media is needed so that the potential viability of seeds can be optimal. Media in nurseries have a large role in helping accelerate budding. The study was conducted in the greenhouse of the Laing Solok Experimental Garden, West Sumatra. The research aimed to know the composition of the media that can improve the viability of cinnamon (Cinnamomum burmanii) seeds. The study was arranged in a completely randomized design with 7 treatments: wastes ash distillation of citronella, burnt husk, sawdust, soil + wastes ash distillation citronella, ground + burnt husk, sand, and soil. All experiment treatment were repeated 5 times. Each treatment was used 30 seeds of cinnamon with a spacing of 5 x 5 cm. The parameters observed included percentage of growth, vegetative growth (seed height, number of leaves, leaf length and leaf width), root length, number of roots, biomass (wet and dry weight of seeds, root wet and dry weight). The results showed that the best growing media for recalcitrant cinnamon seeds were sawdust and soil + ash of citronella refining waste. The growth percentage of the two media were 76.00% and 64.00% respectively, the best vegetative growth, with the wet weight of the seeds respectively 0.74 g and 0.71 g, root wet weight 0.19 and 0.13 g, seed dry weight of 0.25 and 0.23 g, root dry weight of 0.11 and 0.06 g. The best total leaf chlorophill content in both types of media was 0.026 and 0.034.

Abstract

Palmarosa plant (Cymbopogon martini: Poaceae) comes from East India and Turkey, and in Indonesia, it is known as Palmarosa grass. This plant is an essential plant with the name Palmarosa Oil. Besides being useful as a cosmetic ingredient, it can also be an active ingredient in vegetable pesticides. This study aimed to see the effect of applying organic fertilizer to Ultisol soil planting media on the production and quality of Palmarosa plants. The study was conducted at the Laing Experimental Garden, Solok Agricultural Plant Assessment and Research Installation, West Sumatra. Palmarosa plants used were 1 month old in the nursery and transferred to plastic bags measuring 30 x 40 cm. The study was arranged using a Randomized Block Design (RBD) with the following treatments Ultisol soil + Seraiwangi ash (TA), Ultisol soil + manure (TP), Ultisol soil + manure + compost (TK), and positive control andosol soil (K). Comparison of ultisol soil with organic fertilizer 1:1. Each treatment was repeated 8 times, and each replication consisted of 10 sample plants. Observations were made every 15 days after the plants were 15 days after planting. The results showed that the application of organic fertilizer on Ultisol soil + manure + compost showed the best vegetative growth in plant height growth, the number of tillers, leaf length, leaf width, and crown width. While the geraniol content is 81.04% and the oil yield is 0.31%.
