The increase in plant productivity can be achieved by improving the quality of marginal lands (such as dried land, stone land, and mining lands). The efforts of land improvement   include   planting   legume   plant,   application   of   organic   fertilizer   and introducing biological agent like Arbuscular Mycorrhiza Fungi (AMF). The combination of legume plant, AMF inoculation and vermicompost could be an effective method and need to be site tested. A pre-evaluation in finding the compatible AMF type to host and obtaining the best composition of vermicompost to Pueraria javanica growth has been conducted in a green house. This research was factorial experiment in CRD using two factors. The first factor was AMF inoculum type and the second factor was medium formulation. The growth factors measured were plant height, root dry weight, shoot dry weight, total dry weight and AMF propagule number. The research revealed that 20% AMF type of Glomus sp. combined with vermicompost composition treatment + 80% zeolit was the best treatment and capable of  increasing root, shoot and total plant dry weights by 377%, 90%, and 704%, respectively, compared to the control. AMF inoculum type G. etunicatum (selected) and Glomus sp. (endogenous) gave  different  responses  againts  vermicompost addition  in  which  type  G. etunicatum was more tolerant than Glomus sp (endogenous).   The best inoculum were Glomus sp, G.etunicatum and 30 % AMF type Glomus sp combined with vermicompost composition + 70% zeolit treatment, which produced propagule amount 10120 x 104,  308 x10, 77 x 104 per 100 g zeolit, respectively Key words : Pueraria javanica, Arbuscular Mycoriza fungi, vermikompos

RESPON PERTUMBUHAN DAN KETERGANTUNGAN Albizzia saponaria (LOUR.) MIQ TERHADAP INOKULASI FUNGI MIKORIZA ARBUSKULA LOKAL SULAWESI TENGGARA PADA MEDIA TANAH PASCA TAMBANG NIKEL

This study that so far has not been conducted yet by others, regarding the effect of a local AMF species from Southeast Sulawesi on the growth of Albizzia saponaria (Lour.) Miq. The effect of AMF to the plant growth depends on the compatibility between host plant and fungi species which was controlled by genotypes of the both symbionts. The aim of this research is to know the growth respons and dependency of A. saponaria to this local AMF grown in post-nickel mining soil. This research was conducted in the Screen House of Forestry Department, Faculty of Agriculture-Haluoleo University since June to September 2010. A completely randomized design with three replications was used. The treatments were no inoculation of AMF (A), inoculated with -1 -1AMF Mycofer inoculum 5 g polybag (B), and inoculated with local AMF inoculum 10 g polybag (C). The seedling parameter observed were height, diameter, number of leaf, total biomass, number of nodule, percentage of root colonization and relative -1 mycorrhizal dependency (RMD). Results showed the increasing growth and biomass with the application of AMF 10 g polybag (C). There was a positive-strongest correlation value (P<0.01) between percentage of root colonization to all of seedling growth parameters, except to the diameter which was only strong correlated (P<0.05). A. saponaria seedling has high dependency level on local AMF for their survival in heavy metal contaminant soil

The Success of Root Cuttings is Endangered Kalapi (Kalappia Celebica Kosterm.) by Giving Rootone-F Growth Regulator

Kalapi (Kalappia celebica Kosterm.) is endemic in Sulawesi and Endangered species. Plant propagation needs to be done but is constrained by limited seeds. Vegetative propagation of plants can be an alternative method such as using the root cutting technique that has been done previously on other types of species. This study aims to determine the success of vegetative propagation of kalapi (K. celebica), an endangered tree species by root cuttings using Rootone F. as root growth regulator. The research took place from March to June 2019 conducted at the plastic house of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi Branch, Kendari. This study used a Randomized Block Design (RBD) consisting of 6 treatments of Rootone-F concentration: (a) 0 ppm, (b) 100 ppm, (c) 200 ppm, (d) 300 ppm, (e) 400 ppm and (f) 500 ppm. Each treatment was repeated three times and three units of the plant so that the total experimental unit used was 54 units. The results showed that the provision of Rootone-F could increase the success of the growth of kalapi root cuttings. Rootone-F concentration of 500 ppm gives the best results on the percentage of cuttings, percentage of sprouts, percentage of roots, number of shoots and shoot dry weight. The results showed that kalapi can be propagated by root cuttings
