Abstract

Ebony (Diospyros celebica Bakh.) Has a local name as kayu hitam, which is one of the superior tree species in Sulawesi. Ebony wood has a very high economic value because in addition to the beauty of fiber and wood color, ebony also includes exotic species that have high strength and durability. Ebony regeneration rate in nature is relatively low, this is caused by its semi-tolerant nature, where at the ebony seedling level requires shade plants. In addition to shade, mulch also plays an important role in the initial growth process of plants, the use of mulch is able to maintain a more stable soil temperature and is able to retain moisture around plant roots. The research was conducted for 3 months, from December 2015 to February 2016. The research location was in the area of the Faculty of Forestry, Tadulako University, Palu, Central Sulawesi Province. The method used is a completely randomized design (CRD) factorial pattern, which consists of two factors, namely light intensity and type of mulch. The materials used in this study were 6-month-old ebony seedlings, topsoil soil, bokashi fertilizer. Observation of ebony plant growth shows that ebony needs shade at an early stage and requires mulch for the growth process, I1M1 treatment (70% light intensity + 1kg coconut shell charcoal mulch) produces the best height increase of 1.79 cm. The I1M2 treatment (70% light intensity + 1kg sawdust charcoal mulch), the best is 1.30 mm. The I2M1 treatment (90% light intensity + 1kg coconut shell charcoal mulch) did not dominate the growth of leaves much as well as the I2M2 treatment (light intensity 90 + sawdust charcoal) did not dominate the leaf area increase.Keywords: Eboni, light intensity, mulch.

Abstract

One of the obstacles in the cultivation of saga plant (Adenantherapavonina L)  was saga plant’s seeds (Adenantherapavonina L) have the high dormancy properties, it was caused by the hard seed coat which is impermeable to water. An effort to break the dormancy of the saga seeds coat (Adenantherapavonina L)  could be done by scarification. This research was located in PersemaianPermanen BPDAS Palu-Poso which is in the Tadulako University area, Palu, Central Sulawesi from June to August 2019. This research was used Completely Randomized Design (CRD) method with four treatments and ten repetitions. Each repetition consisted of five saga seeds (Adenantherapavonina L). So that the saga seeds needed were 200 seeds. The scarification treatment was given S0 symbol: Without scarification (control), S1: Soaking in a hot water with 100oC temperature for 10 minutes. S2: Cutting on cotyledons, S3: Sanding on all plants of seed surfaces. The treatment of various types of scarification of saga seed germinations (Adenantherapavonina L)very significant effect on germination that is germination, speed of germination and simultaneity of germination. The highest germination, germination speed and simultaneity germination in the S3 treatment, namely sanding on the entire surface of the seed coat.The germination rate of S3 treatment with the highest value was 0.95%. The speed of germination with the highest value was 0.03%. Simultaneity germinated with the highest value of 4.40%. Whereas the lowest germination, germination speed and simultaneity germination were found in S0, that is  without treatment (control) with a value of 0.00%.Keywords: Seed, Germination, Adenanthera pavonina L

Abstract

The use of fertilizers is needed to supply nutrients for plant growth. The use of organic fertilizers on bamboo plants is still rarely done. The purpose of this study was to determine the effect of the dose of solid organic fertilizer and the type of bamboo that gave the best effect and the interaction of the application of solid organic fertilizer and the type of bamboo produced by tissue culture. This research was conducted from July to September 2018, located at the Faculty of Forestry, Tadulako University. The research method used a completely randomized design (CRD) with a factorial pattern, namely the first type of bamboo, B1 petung bamboo and B2 ornamental bamboo. The second factor is solid organic fertilizer P0 = 0 g/clump P1 = 250 g/clump P2 = 500 g/clump P3 = 750 g/clump. With ten treatment combinations of tissue cultured types of bamboo and a dose of solid organic fertilizer. Each treatment was repeated three times to produce 30 experimental units. The results showed that the dose of solid organic fertilizer had a very significant effect on the increase in height and number of bamboo leaves. Furthermore, the treatment of bamboo species had a very significant effect on the growth of the number of leaves but not significantly on other parameters. Meanwhile, the interaction effect between bamboo species and the dose of solid organic fertilizer significantly affected the increase in clump height. The interaction treatment of ornamental bamboo (Bambusa balcooa) + solid organic fertilizer 1000 g/clump (B2P4) gave an average increase in clump height (4.81 cm) significantly different from petung bamboo + solid organic fertilizer 250 g/clump (B1P0), bamboo ornamental + solid organic fertilizer 0 g/clump (B2P0), ornamental bamboo + solid organic fertilizer 250 g/clump (B2P1), and ornamental bamboo + solid organic fertilizer 750 g/clump (B2P3).Keywords: Organic Fertilizer, Petung Bamboo, Ornamental Bamboo
