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

The application of arbuscular mycorrhizal fungi and compost is one of the environmentally friendly technologies to improve the fertility of the planting media so that the results of the seeds are higher of quality. Banana weevil or banana stem is an organic material that has several macro and micro nutrient content, for example N, P and K, and contain chemical compounds in the form of carbohydrates that can stimulate the growth of microorganisms in the soil. Furthermore, arbuscular mycorrhizal fungi (AMF) can increase nutrient uptake from the soil into the roots. The purpose of this research was to determine the effect of the addition of banana weevil compost (Musa balbissiana Colla) and arbuscular mycorrhizal fungi on growing media on the growth of cempaka seedlings (Elmerrillia ovalis (Mig) Dandy). The result of this research showed that the combination of banana weevil compost and arbuscular mycorrhizal fungi on growing media significantly influences the growth of leaf number and dry weight, but no significant effect on growth in height, diameter and wet weight. The combination of banana weevil + soil (P1) compost treatment on growth media gave the growth of cempaka seedlings (Elmerrillia ovalis (Mig) Dandy) better than other treatments. The treatment of banana weevil + soil compost (P1) gives the best effect on all parameters, which is the increase in diameter with an average of 0.70 mm, height increase with an average of 2.70 cm, increase in the number of leaves of 1.70 strands, wet weight with an average of 2.90 g, dry weight with an average of 0.60 g.Keywords: compost,arbuscular mycorrhizal fungi, Elmerrillia ovalis (Mig) Dandy
