ABSTRACT Jambu has spilanthol and phenolic compounds that are responsible for several medicinal properties. Besides improving nutrient absorption, arbuscular mycorrhizal fungi (AMF) can change secondary metabolites’ yield. Thus, the aim of the current study was to evaluate AMF inoculation and P influence on shoot dry biomass yield, macronutrient content (N, P, K, Ca and Mg), total phenol contents and spilanthol percentage in jambu plants. The experiment followed a randomized block design at 3x4 factorial arrangement, with two AMF (Rhizophagus clarus and Claroideoglomus etunicatum) and without AMF, at four P doses (0, 30, 60 and 90 mg/kg of soil), with four replicates. Plants inoculated with R. clarus and C. etunicatum, grown without phosphate fertilization, presented increase by 23 and 12 times, respectively, in comparison to plants without AMF. The relative spilanthol area in plants inoculated with R. clarus, without phosphate fertilization, reached 2.4%. Shoot dry biomass yield of jambu plants and the P, K, Ca and Mg contents were higher when plants were inoculated with R. clarus at the lowest P doses. The AMF also increased the contents of total phenols in plants fertilized with 60 mg kg-1. This P dose increased spilanthol concentration in jambu plants inoculated with C. etunicatum.

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.

ABSTRACT In the establishment of coffee crops, phosphate fertilization is one of the most important soil fertility managements. Aiming to minimize losses, among the options in use are fertilizers with a slow release of nutrients, combined with the inoculation of arbuscular mycorrhizal fungi (AMF). This study aimed to evaluate the initial growth of coffee plants inoculated with AMF and submitted to different types of phosphate fertilizers. The experiment was conducted in a greenhouse, using a complete randomized block design, in a 2 x 4 factorial scheme, with four replications. The first factor referred to the presence or absence of AMF (Rhizophagus clarus) and the second one to phosphate [monoammonium phosphate (MAP)], pelletized organomineral and grainy organomineral fertilizers, as well as a control (without fertilization). The plant height, leaf chlorophyll content, number of plagiotropic branches, leaf area, shoot and root dry matter mass, percentage of root colonization and leaf phosphorus were evaluated. The inoculation with AMF, associated with the pelletized organomineral fertilizer, provided a higher growth for the shoot and root system and higher phosphorus contents, in relation to the other treatments, and it can be an alternative to the implantation or renewal of coffee crops.

ABSTRACT The purpose of this paper was to evaluate the effects of the interference by Urochloa brizantha on coffee seedlings inoculated with arbuscular mycorrhizal fungi. A randomized block design and a 4 x 2 layout was used, where factor A was constituted by seedlings inoculated with Rhizophagus clarus, Claroideoglomus etunicatum and Dentiscutata heterogama, as well as some that were not inoculated, and factor B, constituted by plants in competition or alone. The sowing was conducted on washed sand to produce the coffee seedlings, which, during the matchstick stage, were transplanted into polyethylene bags, and inoculated when showing six pairs of leafs. Then, they were transplanted into pots where they were subjected to interference from two plants of U. brizantha for 90 days, during which time their growth and nutrient accumulation were evaluated on the leaves. As a result, an interaction between the following factors was observed: plant height, leaf area, shoot dry weight, dry weight for roots and P, Mg and Zn content in coffee seedlings. The damaging effect on the growth and P accumulation caused by the weed was reduced in coffee seedlings inoculated with mycorrhiza. Another conclusion was that the inoculation factor increases the competitive power of coffee seedlings.

The objective of this work was to assess the potential of three isolates of arbuscular mycorrhizal fungi to promote growth of micropropagated plantlets of Tapeinochilos ananassae during acclimatization. The experiment was carried out in greenhouse, in a completely randomized block design, with four inoculation treatments: non‑inoculated control and plants inoculated with Glomus etunicatum, Acaulospora longula or Gigaspora albida, with ten replicates. After 90 days, the following parameters were evaluated: survival rate, height, leaf and tiller number, leaf area, fresh and dry biomass, contents of macro‑ and micronutrients in the root and shoot, glomerospore number, and mycorrhizal colonization. The survival percentage was 100%, except for plants inoculated with G. albida (80%). The isolate G. etunicatum is more suitable for plant development, since it improves survival, growth, dry matter production, nutritional status, and vigor of T. ananassae micropropagated plants.

Soybean is one of the most popular food crops for the community, but the needs for soybeans have not been fulfilled by soybean production. To meet the needs of soybeans, it is necessary to intensify agricultural land in Ultisol. This study aims to obtain the optimum concentration of humic acid and dosage of the Arbuscular Mycorrhizal Fungi (AMF) to increase soybean plants' production in Ultisols. This research was conducted from January to April 2020 in Beringin Raya Village, Muara Bangkahulu District, Bengkulu City, at an altitude of 10 m above sea level. The research design used a Randomized Complete Block Design (RCBD) two factors with three replications, arranged factorially in experimental units. The first factor is the concentration of humic acid, consisting of 4 levels: 0, 15, 30, and 45 mL L-1 . The second factor is the dose of AMF, consisted of 3 levels, namely: 0, 2.5, and 5 g plant-1. The results showed that the maximum soybean growth and yield in Ultisols were obtained from the humic acid concentration at 45 mL L-1 at the dose of AMF at 2.5 g plant-1 . The resulting production potential is 1.99 tons ha-1 . The administration of humic acid or AMF independently at this research stage had not yet given a maximum response to the growth and yield of soybean in Ultisol.

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.

Abstract It is urgent to restore the ecological function in open-pit mining areas on grassland in Eastern China. The open-pit mines have abundant of mining associated clay, which is desirable for using as a soil source for ecological restoration. The mining associated clay in Hulunbuir district, Inner Mongolia was selected and mixed with a sandy soil at a ratio of 1:1 (S_C soil). Also, effects of arbuscular mycorrhizal fungi (AMF) inoculation on soil functions were studied. The aboveground and underground biomass of maize in S_C soil was 1.49 and 2.41 times higher than that of clay soil, respectively. In the topsoil and S_C soil, the growth hormone (IAA) and cytokinin (CTK) levels of maize were higher than that of clay, while abscission acid (ABA) levels were lower. The inoculation with AMF could significantly improve the biomass of maize and enhance the stress resistance of plants. Through structural equation model (SEM) analyses, it was found that the soil type and AMF inoculation had the most direct impact on maize growth and biomass content. These finds extend our knowledge regarding a low-cost method for physical and biological improvement of mining associated clay, and to provide theoretical support for large-scale application in the future.
