Sugar palm is one of local plants spesies that may potential for reclamation program because can be planted under the stands of forest crops. Forest crops can be shade seedlings sugar palm from direct sunlight because the growth of sugar palm is relatively slow. Sugar palm can be useful even without cutting down the trees. Previously, sugar palm had been planted at PT Berau Coal and had produced fruit. The research was conducted at coal post-mining land of PT Bukit Asam, Tanjung Enim, South Sumatera. The research using combination of AMF and liming treatment is as follows, ie MaK0 (control), Mak1 (seedling with AMF without inoculation; liming 30 g plant-1), MiK0 (AMF indigenous seedling inoculation; without liming), MiK2 (AMF indigenous seedling inoculation, liming 60 g plant-1), MmK0 (AMF mycofer seedling inoculation; without liming), and MmK3 (AMF mycofer seedling inoculation, liming 120 g plant-1). The results showed that sugar palm could be grown in the coal post-mining land. The combination of AMF and liming treatment did not significant effect on observed variables of plant height, rachis length, diameter, leaves number, number of spore and root cholonization. Sugar palm seedlings that have been infected with AMF could be grown and provide a good growth response even without liming.Keywords : Arbuscular Mycorrhizal Fungi (AMF), marginal land, sugar palm

Amf Inoculation

Arbuscular mycorrhizal fungi (AMF) is known to improve the growth of shallot (Allium cepa var. aggregatum) and strengthen the resistance of plants toward disease infection.  This research aimed to find out the roles of AMF in suppressing the development of purple blotch disease caused by  Alternaria sp. on shallot in Caturtunggal, Sleman, Yogyakarta.  Inoculation of AMF either on fertilization of N, P, K or without fertilization treatment resulted on higher plant height and number of leaves compared to those without AMF inoculation. The plant inoculated with AMF had lower purple blotch disease intensity and disease progression than control and fungicide treatment. The result showed that AMF, in addition to act as the bio-fertilizer, is a potential to be a biocontrol agent.

AbstractDeficit irrigation (DI) improves water use efficiency (WUE), but the reduced water input often limits plant growth and nutrient uptake. The current study examined whether arbuscular mycorrhizal fungi (AMF) could alleviate abiotic stress caused by low phosphorus (P) fertilization and DI.A greenhouse experiment was conducted with potato grown with (P1) or without (P0) P fertilization, with AMF (M1+:Rhizophagus irregularisor M2+:Glomus proliferum) or AMF-free control (M−) and subjected to full irrigation (FI), DI or partial root-zone drying (PRD).Inoculation of M1+ and M2+ maintained or improved plant growth and P/nitrogen (N) uptake when subjected to DI/PRD and P0. However, the positive responses to AMF varied with P level and irrigation regime. Functional differences were found in ability of AMF species alleviating plant stress. The largest positive plant biomass response to M1+ and M2+ was found under FI, both at P1 and P0 (25% increase), while plant biomass response to M1+ and M2+ under DI/PRD (14% increase) was significantly smaller. The large growth response to AMF inoculation, particularly under FI, may relate to greater photosynthetic capacity and leaf area, probably caused by stimulation of plant P/N uptake and carbon partitioning toward roots and tubers. However, plant growth response to AMF was not related to the percentage of AMF root colonization. Arbuscular mycorrhizal fungi can maintain and improve P/N uptake, WUE and growth of plants both at high/low P levels and under FI/DI. If this is also the case under field conditions, it should be implemented for sustainable potato production.

Okra is a vegetable crop that has a high selling value and the production of okra is more exported than sold domestically. The demand for okra from year to year continues to increase from various countries, especially Japan, which imports the most okra from Indonesia. Fertilization of phosphorus (P) fertilizer to fulfill nutrients and provision of arbuscular mycorrhizal fungi (CMA) for more efficient and maximum absorption by plants. Phosphorus (P) fertilizer can increase the production and quality of okra. The aim of this study was to determine the combination of treatment of arbuscular mycorrhizal fungi and which dosage of P fertilizer was best to increase the yield of okra production. The design used was a completely randomized design (CRD) with factorial treatment consisting of two factors. The first factor is the dose of arbucular mycorrhizal fungi (CMA) consisting of 4 levels, namely (0; 160; 320; 480) and the second factor is the dose of P fertilizer (75; 100; 125; 150). Parameters observed were plant height, number of leaves per plant, volume of roots, number of fruits per plant, weight of fresh fruit per plant and weight of plant dry corpse. Based on the analysis of variance, it showed that the interaction was significantly different on the variables of root volume, plant height, number of fruits and fruit weight. Based on research, the CMA dose of 320 kg / ha and the dose of 125 kg / ha gave the highest production results.

Abstrak. Ultisol merupakan salah satu tanah marginal yang memerlukan pengelolaan yang tepat untuk meningkatkan kesuburannya. Penelitian ini bertujuan untuk mengetahui pemberian Fungi Mikoriza Arbuskula (FMA) dan kompos limbah kakao terhadap kolonisasi FMA, dan pertumbuhan bibit kakao pada Ultisol. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola faktorial dengan dua faktor perlakuan dan tiga ulangan. Faktor pertama adalah jenis FMA yaitu tanpa FMA (F0), Glomus sp (F1), dan Glomus sp. + Gigaspora sp. (F2). Faktor kedua adalah dosis kompos yaitu 0 ton.ha-1 (K0), 20 ton.ha-1 (K1), dan 30 ton.ha-1(K2). Hasil penelitian menunjukkan bahwa FMA berpengaruh nyata terhadap kolonisasi mikoriza, namun tidak berpengaruh nyata terhadap tinggi tanaman  pada 30, 60, 90 HST, diameter batang pada 30, 60, 90 HST, dan luas daun pada 90 HST.  Pemberian kompos limbah kakao berpengaruh nyata terhadap tinggi tanaman pada 90 HST, namun tidak berpengaruh nyata terhadap tinggi tanaman pada 30 dan 60 HST, diameter batang pada 30, 60 90 HST, dan luas daun pada 90 HST.  Kombinasi FMA dan kompos limbah kakao berpengaruh nyata terhadap diameter batang pada 30 HST namun tidak berpengaruh  nyata terhadap tinggi tanaman pada 30, 60, 90 HST, diameter batang pada 60 dan 90 HST, dan luas daun pada 90 HST. Perlakuan FMA jenis Glomus sp. + Gigaspora sp. dan kompos 20 g.pot-1 memberikan pengaruh terbaik terhadap kolonisasi mikoriza dan pertumbuhan tanaman. The effects of arbuscular mycorrhizal fungi and compost of cocoa waste on myccorrhiza colonization, and the cocoa seedling growth on UltisolAbstract. Ultisol is one of marginal soils which requires proper management to increase its fertility. This study aims to determine the administration of Arbuscular Mycorrhizal Fungi (FMA) and cocoa waste compost to FMA colonization, and the growth of cacao seedlings on Ultisols. This research used factorial randomized block design (RBD) with two treatment factors and three replications. The first factor is the type of FMA that is without FMA (F0), Glomus sp (F1), and Glomus sp. + Gigaspora sp. (F2). The second factor is the compost dose which is 0 tons.ha-1 (K0), 20 tons.ha-1 (K1), and 30 tons.ha-1 (K2). The results showed that FMA significantly affected mycorrhizal colonization, but did not significantly affect plant height at 30, 60, 90 HST, stem diameter at 30, 60, 90 HST, and leaf area at 90 HST. Cocoa waste compost has a significant effect on plant height at 90 HST, but no significant effect on plant height at 30 and 60 HST, stem diameter at 30, 60 90 HST, and leaf area at 90 HST. The combination of AMF and compost of cocoa waste significantly affected the stem diameter at 30 HST but did not significantly affect the plant height at 30, 60, 90 HST, stem diameter at 60 and 90 HST, and leaf area at 90 HST. Treatment of FMA type Glomus sp. + Gigaspora sp. and compost 20 g.pot-1 provides the best effect on mycorrhizal colonization and plant growth.
