Abstract

The problems that are still faced at this time include the lack of enviromentally sound cultivation technology to support teak growth rates quickly and efficiently. One of the efforts to overcome this problem is to use a Gyberelin (GA3) growth regulator, which isknown to accelerate plant growth, so that dwarf plants can grow taller in a relatively short time. The research aims to determine the effect of various concentration s of administration of Gyberelin (GA3) grawth regulators on teak seedlings (Tectona grandis L.f) in nurseries. This research uses a completely randomized design method consisting of four treatments, namely G0= (Control), G1= 100 ppm, G2= 200 ppm, G3= 300 ppm. The results of the research showed that the addition of various concentrations of Gyberelin hormone in the nursery had a significant effect o the height increase and increase in the number of teak seedling leaves, but it did not signficantly affect the diameter of teak seedlings. Treatment of Gyberelin (GA3) with a concentration of 300 ppm (G3) gave the best influence on teak growth in terms of height increase and number of leves compared to control treatment (G0), as well as concentration 0f 100 ppm (G1) and 200 ppm (G2).

Abstract

Ketapang (Terminalia catappa L.) is one of plant that can grow in critical land like reeds field. Imperata cylindrical (L.) Raeusch is one of plant that can secrete allelopathic substances that is chemicals and it is found on the plants body which is put outside into the environment so it can inhibit or ruin the other plants by using Arbuscular Mycorrhiza Fungi (FMA) as biological fertilizer can increase water absorption and nutrient from the soil. This research used Complete Random Design (CRD) method, and consisted of 4 treatments of arbuscular mycorrhiza fungi that are P0= Without treatment (control), P1= FMA 10g/seedling, P2= FMA 15g/seedling, and P3=FMA 20g/seedling. From the 4 treatment levels, each of them is repeated for ten times, so the total of seedling units that be needed are 4x10=40 (forty) seedling units. The result of this research showed that by giving some dose of arbuscular mycorrhiza fungi type of inoculums consortium by 4 genus (Acaulospora, Gigaspora, Glomus, and Scutellospora), have a real impact toward all the observation parameters that are the high accretion, the diameter accretion, the number of leave accretion, canopy wet weight, root wet weight, crown dry weight, and root dry weight. The treatment dose FMA for 20g (P3) on the polybag gives the mean score of high accretion, diameter, and the biggest number of leave. It show that more and more the high dose of FMA that is applied, than the growth of Ketapang seedling is also getting better because by giving FMA, it can influence the allelophatic substance in the growing media.Keyword: Ketapang, Allelophatic, and Mycorrhiza.

Abstract

(Anacardium occidentale L.) is a conservation plant and its development in Indonesia has been started since 1975 through the Ministry of Forestry's project as a conservation plant to repair critical land. The study was conducted for three months, starting from March to May 2018. The research location was located in the nursery around the Forestry Science Laboratory of the Faculty of Forestry. This study uses a factorial Randomized Complete Design Method (RAL) consisting of two factors, namely the first factor of light intensity C1 = 30%, C2 = 50%, C3 = 70% and C4 = 100% and the second factor is the dose of Urea P0 = without Urea fertilizer, P1 = 1 g and P2 = 2 g per polybag. The combination of the two factors is 12 combinations and each treatment is repeated 4 times. The parameters observed included height increase, increase in diamater, increase in number of leaves and measurement of leaf area. The results of this study indicate that the treatment of Urea fertilizer dosage has a very significant effect on the increase in cashew nut seedlings aged 12 MST. The treatment of 2 g fertilizer dose gave a high increase of 2.0 cm which was significantly different from the treatment without fertilizer (P0) which was 1.4 cm. In addition, the treatment of light intensity and its interaction with Urea fertilizer has no significant effect on all observational parameters of age 12 MST. The treatment of 30% light intensity gave the best results for height increments of 2.0 cm and an increase in diameter of 0.82 mm at 12 MST. The interaction of light intensity and urea fertilizer (C1P2) tended to give the best effect on the parameters of high increase of 2.5 cm, the increase in diameter of 0.82 mm and the increase in the number of leaves of 2.4 strands aged 12 MST.Keywords: Light Intensity, Cashew Seed Urea Fertilizer (Anacardium Occidentale L).

Abstract

Ultisols are mineral soils that develop from old parent materials and have undergone further weathering. Constraints to the utilization of ultisol soils have low organic matter content, acidic soil reactions, low base saturation, high Al content and have a clay to sandy clay texture. Therefore, to reforest it, it is necessary to look for tree legumes that are adapted to grow in these soil conditions. The purpose of this study was to determine the growth of several species of legume seedlings on ultisol soil in polybags. This research was conducted for three months, from November 2020 to January 2021, located in the BPDASHL Permanent Nursery in Palu-Poso, Palu, Central Sulawesi. This study used a completely randomized design (CRD) method with four treatments and ten replications, so that there were 40 experimental units. The treatments were applicated, namely: L1 = Sengon (Paraserianthes falctaria (L.) Nielsen); L2 = Acacia (Acacia mangium Willd); L3 = Johar (Senna siamea Lamk); L4 = Turi (Sesbania grandiflora L). The parameters observed in this study were seedling height, diameter, number of leaves, value of stem stiffness and number of root nodules. The result of study showed that legume seedlings had different growth responses on ultisol soil in polybags. The Sengon (Paraserianthes falctaria (L.) Nielsen) legume species had higher height, diameter, leaf number, seedling firmness and number of noduoles compared to (L4) Turi (Sesbania grandiflora L), (L3) Johar (Senna siamea Lamk), (L2) Acacia (Acacia mangium Willd) legumes.Keywords: Legume tree, ultisol soil
