“…The interaction between the host plant, AMF species, and type of growth substrate can be stimulatory or inhibitory to the AMF and host and amongst all, type and the concentration of substrate used is foremost for AMF multiplication. As per Moreira et al (2019), regardless of the inoculum source, the percentage of viable spores exists greater at the layer of 0.00-0.05 m (76.32 %) compared to the layer of 0.05-0.10 m (72.05 %). Soil amendment up to this range of depth could be productive.…”

“…Consequently, farmers and nursery owners can conventionally multiply AMF in pots or small plots or nursery beds at their place by utilizing different hosts and substrates, whichever is available. AMF inoculum encompasses spores, sporocarps, mycelium and colonized root segments (Gupta, 2017;Moreira et al, 2019). A nurse plant with high efficiency of mycorrhization and selection of suitable material for the multiplication and delivery of AMF spores and hyphae is essential.…”

Article InfoThis experiment was carried out to assess the effect of soil amendment with different concentrations of municipal sewage sludge (SS) as a substrate on inoculum production of two selected arbuscular mycorrhizal fungi (AMF) i.e., Glomus mosseae and Acaulospora laevis. The experiment was a 4 × 5 factorial design with four hosts including, maize (Zea mays L.), lemon grass (Cymbopogon nardus (L.) Rendle), palmarosa (Cymbopogon martini (Roxb.) Wats.) and Sesbania (Sesbania aculeata Poir.) and the following five SS concentrations 1) no substrate, 2) 25 g, 3) 50 g, 4) 75 g and 5) 200 g pot -1 ) with five replications. After 90 days, the host roots and its rhizosphere soil were examined for fungal mycorrhization in terms of percent of root colonization and AMF spore quantification. Furthermore, we calculated the response of each host in terms of increase in plant height (cm), root length (cm), root, fresh shoots, and dry weight (g). Mycorrhization pattern showed moderate to abundant intraradical mycelium, extraradical mycelium, vesicles, and arbuscules in all the host plants. This pattern varied with a change in the input level of SS. The 75 g treatment obtained the maximum mycorrhization of both the AMF, while the highest input level was detrimental to AMF and host plants' survival. Among the tested hosts, lemon grass and maize had a tremendous increment in G. mosseae and A. laevis inoculum respectively. Consequently, 75 g SS with lemon grass is the most compatible hostsubstrate combination capable of maximum G. mosseae and A. laevis spore production and root colonization and so far, highlights the significance of an alternative, cost-effective and affordable carrier medium that can be adopted by farmers as sustainable cultural practices for on farm AMF inoculum production.

“…Besides the promising likelihood of producing inoculants on-farm (Chaiyasen et al, 2017;Moreira et al, 2019), AMF multiplication in non-sterile substrates does not impair such a production. The efficiency of AMF introduced on-farm depends on their competitiveness with endogenous microbiota, in terms of infective capacity, inoculum density, propagules' distribution, fungal ability to produce external hyphae, hyphae's ability to colonize roots fast, and the ability of the introduced fungi to maintain colonization rates under competitive conditions (Goetten et al, 2016).…”

“…The viability of directly producing mycorrhizal inoculants in rural properties allows farmers and nurseries to have access to the most effective strains in order to meet their conditions, whether it is host culture, soil type and climatic conditions. The production of mycorrhizal seedlings adds value and quality and allows producers to have access to these beneficial fungi, which have positive effects on plant production (Schlemper & Stürmer, 2014;Goetten et al, 2016;Chaiyasen et al, 2017;Moreira et al, 2019), as well as enables using substrates that can be easily obtained in rural properties.…”

Selecting alternative sterile and non-sterile substrates for mycorrhizal inoculant production

Alternative substrates were evaluated for mycorrhizal inoculants production considering the beneficial effects of arbuscular mycorrhizal fungi (AMF) for plants and environment. The first step of the experiment aimed at evaluating the potential of substrates produced from sugarcane bagasse (SB), coconut fibre (CF) and urban waste compost (UWC) to produce AMF inoculants, by using Brachiaria decumbens as multiplier plant. The experiment has followed a randomized block design, at 7x3 factorial arrangement (seven substrates: SB, CF,

“…Some studies have shown the advantages of inoculation with AMF in low fertility soils (Barea et al, 2002) and tropical crops (Rodríguez-Romero et al, 2011). Few studies have shown the benef its of inoculation with mycorrhizal fungi in pineapple, most of them evaluate micro-propagated plants during the acclimatization stage (Thamsurakul et al, 2000;Rodríguez-Romero et al, 2011;Moreira et al, 2019). In Mexico, pineapple production is still based on a strict vegetative process by planting sprouts (Uriza-Ávila et al, 2018) where the high use of P fertilizer conflicts with any potential use of mycorrhizal associations to promote, not only plant nutrition and growth but also biological control, drought resistance, and soil structure and quality.…”

A strategy to increase the productivity of pineapple agricultural systems is the excessive application of chemical fertilizers. In the state of Veracruz, Mexico, pineapple fields are being fertilized with P (180 to 240 kg ha-1) to maximize yields so that fertilizer applications keep increasing. We assessed the interaction between chemical phosphorus fertilizers, the establishment of mycorrhizal associations and biomass production of Cayenne, Champaka, and MD2 cultivars of pineapple in a greenhouse experiment. Plants were inoculated with a mycorrhizal consortium and grown with 0, 80, 200, 300, 500, and 600 mg phosphorus kg-1 soil additions in 8 kg pots for 8 months. Phosphorus reduced mycorrhizal colonization already at the lowest phosphorus fertilization dose in two of the three cultivars and became minimal for all cultivars from 200 mg P kg-1 soil. At the two highest phosphorus fertilization levels, shoot dry biomass and the dry weight of leaf D was reduced in all cultivars. The results show that the farmer´s practice of adding excessive fertilizer as an insurance principle is reaching the levels where fertilization is becoming detrimental for production and mycorrhizal benefits for the crop and the soil are being eliminated.
