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 use of mycorrhiza is a promising biotechnology that makes coffee cultivation sustainable in the use of fertilizers. In this sense, plant growth and phosphorus contents were assessed in coffee inoculated with Rhizophagus clarus, Claroideoglomus etunicatum and Dentiscutata heterogama in soil fertilized with 0, 0.74, 1.48 and 2.96 g P2O5 kg-1. The experimental design was a randomized block design in a 4 × 4 factorial scheme with four replications. The mycorrhizal seedlings were previously produced and later transplanted to pots, simulating the field planting. The assessments were performed 150 days after transplanting. All variables were influenced by inoculation, but the effects were dependent on P doses. P doses higher than 50% of the recommended dose (0.74 g P2O5 kg-1) decreased the benefit of mycorrhiza. The fungi Rhizophagus clarus and Claroideoglomus etunicatum promoted a higher growth of coffee plants when compared to non-inoculated plants in non-sterilized soils and with a reduction in the applied P.

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.

Microorganisms are essential for maintaining soil quality, among which stand out the fungi. The association with arbuscular mycorrhizal fungi (AMF) and phosphorous solubilizing fungi (PSF) in its rhizosphere can benefit citrus plants, since these fungi can contribute to an increase in plant development due to the greater availability of water and nutrients. The present study aimed to evaluate if the amount of total fungi, AMF and PSF in the rhizosphere can be affected by the Citrus varieties. Soil samples were collected from the experiment conducted in a randomized block design (RBD) with six Citrus varieties (Page, Pera D9, D12 Pera Pera C21, Pineaple and Ruby). Regarding the evaluated quantitative variables, there was a significant negative simple linear correlation only between the mycorrhizal colonization (MC) and the number of colony forming unit (CFU)/mL of PSF. The number of CFU/mL of soil FPS did not differed statistically between the Citrus varieties rhizosphere, but for total (TF) fungi a significant difference was observed, especially for the ‘Pineaple’, variety that provided higgher mean for the number of CFU/mL, differing from the ‘Page’ variety. All Citrus varieties presented root colonization by AMF and there was a significant difference among the evaluated varieties, however only ‘Rubi’ and ‘Pineaple’ differed from the others. Citrus varieties do not affect PSF quantity nor MC percentual in their rhizosphere but ‘Page’ and ‘Pineaple’ varieties stand out for glomerospores quantity of AMF and TF CFU/mL.

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 Soil and plant beneficial microbes capitalize plant nutrition through successful colonization in roots rhizosphere which could sustainably increase cereal production. Zinc (Zn) is intensively reported a deficient nutrient for maize and wheat production in Brazilian Cerrado, which could be sustainably managed by beneficial microorganisms and their symbiotic association with other microorganisms like arbuscular mycorrhizal fungi (AMF) and dark septate endophytes (DSE). The objective of this study was to evaluate the effect of Azospirillum brasilense inoculation and residual Zn rates on root colonization and grain yield of maize and wheat in succession under Brazilian Cerrado conditions. These experiments were conducted in a randomized block design with four replications and arranged in a 5x2 factorial scheme. The treatments were consisted of five Zn rates (0, 2, 4, 6 and 8 kg ha-1) applied from zinc sulfate in maize and residual on wheat, and without and with seed inoculation of A. brasilense. Both crops were evaluated for root colonization of AMF and DSE, number of spores of AMF, quantification of CO2-C and grain yield. Colonization by AMF and DSE were significantly increased with interaction of Zn rates and inoculation treatments. The inoculation of A. brasilense favored root AMF and DSE colonization while increasing Zn rates by 4 kg ha-1 for maize and while 2 and 4 kg ha-1 Zn in residual for wheat reduced these colonizations. The inoculation did not influence spore production and CO2-C in both crops while maize-wheat yield were increased with Zn rates up to 4 kg ha-1 in edaphoclimatic condition of Brazilian Cerrado.

Mining results in major landscape changes. Restoring areas after exploitation of natural resources can be accomplished through adopting techniques used to optimize the restoration process. Among such techniques, planting seedlings of species adapted to adverse edaphoclimatic conditions and which have interspecific associations with microorganisms stand out. One of these indigenous species which occur in the Southern Espinhaço Mountain Range with potential for use in restoring degraded areas is Kielmeyera rubriflora (Spreng) Mart. Thus, the objective of this study was to evaluate the influence of inoculating arbuscular mycorrhizal fungi on the survival and growth of Kielmeyera rubriflora Cambess. on two substrates from iron mining. The experiment was carried out in a nursery of the UFVJM Plant Species Propagation Center (CIPEF) in a randomized block design and treatments arranged in a 2 x 2 factorial design, using two iron mining substrates and inoculated and uninoculated plants with five repetitions. The seedlings received 25 g of the soil-inoculum mixture of Paraglomus occultum (C. Walker) JB Morton & D. Redecker and Claroideoglomus etunicatum (WN Becker & Gerd) C. Walker & A. Schüßler at the transplantation time to 17 dm3 pots. Stem diameter and leaf number were influenced only by the main effects of substrate and inoculation, while plant height was influenced by the interaction between substrate and inoculation. Inoculation with mycorrhizal fungi in Kielmeyera rubriflora ensures survival, species growth and root development on both iron mining substrates and is a suggested strategy for planting in areas degraded by iron mining.

SUMMARYDespite previous research on mycorrhizal association with plants, the data on associations with coffee (Coffea species) are very sparse despite the great economic importance of this crop for many tropical developing countries. The present paper reviews the main aspects of the association between arbuscular mycorrhizal fungi (AMF) and coffee plants. This review includes topics on mycorrhizal effects on coffee nutritional status, pathogen–AMF interactions and responses to several environmental stresses. It also summarizes findings about the natural occurrence of AMF in different soils in which coffee is cultivated, some ecological aspects of this specific association and outlines trends for future investigations, which must elucidate the real benefits of mycorrhizae to coffee plants.

Hydrogel and mulch added to the soil may favor arbuscular mycorrhizal fungi (AMF), contributing to the reforestation of disturbed lands in semiarid regions. This study aimed to evaluate AMF colonization in the roots of Enterolobium contortisiliquum (Vell.) Morong in response to the application of hydrogel and mulch (bagana) from carnauba palm (Copernicia cerifera L.) to the soil and their effects in the soil and plants. A field experiment was set up in April 2014 in Ibaretama (Ceará, Brazil) in a randomized block design in a 2×4 factorial scheme – with mulch (+M) e without mulch (−M) × hydrogel doses (0, 4, 5, and 6 g L−1) –, with five replicates. Samples of roots, soil, and leaves were collected 18 months after the beginning of the experiment to determine AMF colonization in the roots and nutrient contents in the soil and plant material. The hydrogel dose of 6 g L−1 and mulch application equivalent to 10 Mg ha−1 increased AMF colonization by 21 e 44%, respectively. Soil contents of Ca, K, and Zn decreased with hydrogel doses without mulch but increased in the presence of the carnauba palm residue applied as mulch. A higher P content in the plant material was not associated with AMF colonization. The leaf content of Ca responded only to the treatment with mulch, reaching the highest value (3.8 g kg−1) in the absence of mulch.
