Ex-limestone mining quarry has poor soil fertility, both biological, chemical, and physical condition due to the mining process. Marginal land conditions such as ex-limestone mining quarry require high survival seedlings. Application of ectomycorrhizal fungi is an alternative that can be done to improve the success of restoration. Acacia mangium is one of the plants that could be colonized by many types of mycorrhizal such as ectomycorrhiza. This research aimed to determine the growth of A. mangium seedlings in ex-limestone mining growth media and the effect of ectomycorrhiza application on the growth of A. mangium. The research used a completely randomized design with six treatments and five replications. Treatment consisted of 100% soil with mycorrhiza, 100% soil without mycorrhiza, 50% soil + 50% limestone tailings + mycorrhiza, 50% soil + 50% limestones tailings without mycorrhiza, 100% tailing with mycorrhiza and 100% tailing without mycorrhiza. The seedlings used in the study germinated from seeds taken from Lampung Timur Regency. The seeds germinated in sand for one month, then used as the research material. The measurement taken were  height, diameter, number of leaves, leaf area, measured were root length, canopy dry weight, and total dry weight. The colonization of ectomycorrhiza is measured by counting the percentage of colonization. The symbiosis with rhizobium measured by number of root nodules. Data were tested for variance analysis, followed by Least Significance Different Test at significant level of 1% and 5%. The results showed that the percentage of A. mangium life was high, reaching 100%. All growth parameters showed that plant colonized by mycorrhiza has remarkably better values compared to non-mycorrhiza plants.Keywords: limestone, ectomycoriza, mangium, phytoremediation

Abstract. Respatie. D. W, Yudono P, Purwantoro A, Trisyono Y.A. 2019. The potential of Cosmos sulphureus flower extract as a bioherbicide for Cyperus rotundus. Biodiversitas 20: 3568-3574. Cosmos (Cosmos sulphureus Cav.) flower is recognized as natural source of bioherbicide compounds for several weeds. The purple nutsedge (Cyperus rotundus L.) is an important weed, and this research was aimed to determine the effects of cosmos flower extract on this weed. Dried cosmos flowers were threshed and extracted using maceration method with 70% alcohol. The experiment was conducted in the greenhouse using a completely randomized design (CRD) with three replications. Purple nutsedge tubers were planted in polybags and treated with cosmos flower extract applicated once to three times with 300 mL polybag-1 at the concentration of 40%. Different levels of inhibitions on purple nutsedge growth were observed at 30 and 60 days after sowing (DAS) due to the presence of gallic acid in the extract. Growth parameters for purple nutsedge were analyzed using Analysis of Variance (ANOVA) and followed by Least Significant Differences (LSD) at α=0.05. Significant reductions in the number of mother shoots, daughter shoots, and roots, length of mother leaves, length of rhizomes, root, and total leaf area of the purple nutsedge treated with the cosmos flower extract at 30 DAS compared to those in the control. A significant reduction was also observed in foliage dry weight, underground organs dry weight, and total dry weight of purple nutsedge. The three application times yielded maximum inhibition. In addition, these treatments reduced N, P, and  K content, chlorophyll content, and photosynthesis rates at 30 DAS. These results suggest that cosmos flower extract has the potential for controlling purple nutsedge.

This study investigated the effect of growth media on the germination and early growth of Tetrapleura tetraptera (Shum andThonn) This was assessed at the Forestry Nursery Federal University of Agriculture Makurdi, Benue State, Nigeria.  Two hundred (200) viable seeds were immersed in 50% sulphuric acid at 15mins. The seeds after pretreated were sown on five different media namely: Top soil, Sawdust, Riversand, mixture of topsoil and riversand and mixture of riversand and sawdust. Completely Randomized Design was adopted for this experiment. Data were collected on percentage germination on daily basis for 4 weeks, growth parameters involving seedling height, number of leaves, girth and leaf length at 2 weeks interval for 8 weeks. Analysis of Variance (ANOVA) was used to analyze the data collected. Mean separation was carried out for significantly different parameter by using Duncan’s Multiple Range Test (DMRT) to determine the suitable growth media. The result showed that germination percentage was significant as 5% level of probability (p>0.05) and the highest germination percentage of 80% was recorded in Riversand+Sawdust. Growth parameters were also influenced by growth media.  The highest number of leaves was observed in topsoil(10.05), seedling height (7.88cm) in Riversand +sawdust, girth(0.57cm) in topsoil and leaf length (4.71cm) in sawdust.  In raising the seeds of Tetrapleura tetraptera , Riversand and sawdust should be used. To encourage domestication and conservation of Tetrapleura tetraptera, topsoil,  mixture of riversand and sawdust should be adopted since we are interested in growth of tree species and this will ensure the production of vigorous seedlings for its plantation establishment.Keywords: Growth media, domestication, germination, Tetrapleura tetraptera
