“…However, the percentage of root infections from upland rice between biochar rates was similar as indicated in Figure 2B. This phenomenon explains that the colonization of rice roots by arbuscular mycorrhizae is influenced by several abiotic and biotic environmental factors [54], which include soil moisture, temperature, nutrient availability, growth factors, rice phenology, and root turnover [55].…”

Biochar has the capacity to influence soil fertility, mycorrhizal arbuscular fungi (AMF), and upland rice growth. Therefore, this study aimed to assess biochar addition on soil character and investigate the effect on AMF, growth, yield, and nutrient uptake of upland rice local. Four levels biochar rate (%, w/w) of 0%, 2.5%, 5.0%, and 7.5% was tested in a pot experiment. The results showed that pH, C-org, tot-N, and C and N-ratio increased linearly, while P-available quadratic, and K-exchange increased exponentially with biochar rate. At 60 and 90 days after planting, the height of a plant containing 7.5% biochar was significantly high. The roots and shoots ratio showed the highest and lowest values at 0% and 7.5% biochar rates. Furthermore, the filled spikelet percentage at a 5.0% was the most significant among the others. The biochar rate increased the straw P and K uptake, but N was insignificant and N and P ratio was decreased. Total AMF spores were reduced with biochar addition, and the difference in the proportion of infected roots was not statistically significant. There was a positive correlation between total spikelet per panicle with P and K uptake and a negative correlation with N and P ratio and total AMF spore. The filled spikelet negatively correlated with K uptake, and biochar addition to soil fertility increased. The 5% addition had a better effect on yield component and nutrient uptake of P and K by the local upland rice on acidic soil.

“…At present, there are only a few studies that provide information on the effects of AMF species on black rice. Surendirakumar et al [23] reported seven species of AMF associated with black rice in paddy soils in India, including one species of Acaulospora and two species of Rhizophagus. However, the very different environmental conditions in that study (paddy rice) and this study (aerobic rice) would make a direct comparison difficult.…”

Arbuscular Mycorrhizal Fungi Enhance Growth and Increase Concentrations of Anthocyanin, Phenolic Compounds, and Antioxidant Activity of Black Rice (Oryza sativa L.)

Black rice (Oryza sativa L.) contains high concentrations of bioactive compounds that are associated with human-health benefits. Arbuscular mycorrhizal fungi (AMF) can increase plant performance and concentrations of these bioactive compounds. In a pot experiment, the effects of four different species of AMF (Claroideoglomus etunicatum; Rhizophagus variabilis; Rhizophagus nov. spec.; Acaulospora longula) were assessed on growth performance, grain yield, concentrations of phenolic compounds and anthocyanin, and antioxidant activity of two black-rice cultivars. The experiment was a completely randomized factorial design with two factors, viz. cultivar (Niew Dam Hmong and Maled Phai) and treatment (four different species of AMF and two non-inoculated treatments, without and with mineral fertilizer). Results showed that cultivar, treatment, and their interaction were almost always significant sources of variation for both plant performance parameters and concentrations of bioactive compounds. Maled Phai showed higher performance and higher concentrations of phenolics and anthocyanins but lower antioxidant activity than Niew Dam Hmong. The non-inoculated treatment without mineral fertilizer showed the lowest performance. The non-inoculated treatment with mineral fertilizer resulted in larger root and shoot biomass than the mycorrhizal treatments, but grain yield was higher in the mycorrhizal treatments. Inoculation with R. variabilis resulted in the highest concentration of phenolics and anthocyanins. We conclude that R. variabilis was the best inoculum for increasing grain yield and bioactive compounds, especially in Maled Phai.

“…When the plant reaches the heading and ripening stages (6-9 weeks for a 3-month cultivar), the aerenchyma is fully developed, and with that sufficient O 2 supply is received by AMF to form the higher colonization with rice roots [12]. Moreover, AMF colonization can vary with geographical regions, temperature, rainfall, nutrient availability, soil pH, soil type, and altitudinal gradients [12,[23][24][25][26][27]. In this study, the colonization was assessed using 6-9-week-old plants, assuming that at this stage all plants form a higher colonization percentage.…”

Arbuscular mycorrhizal fungi (AMF) have the potential to maintain the sustainability of rice cultivation via maintaining soil health. The objective of this study was to produce an AMF-based biofertilizer for the rice variety Bg350 using indigenous dominant species of AMF that are adapted to paddy wetland soil conditions in dry, wet, and intermediate zones in Sri Lanka and are co-inoculated with the bacterium Azospirillum. A pot experiment was carried out to evaluate the effectiveness of the produced biofertilizer using the rice variety Bg350. Treatments were inorganic fertilizer, compost, biochar, produced AMF-biofertilizer [1 kg of ground carrier material inoculated with 50 g of AMF propagules and 20 mL of 1.5 × 108 (CFU/mL) of Azospirillum], and the control. A two-factor factorial, completely randomized design was used under sterilized and non-sterilized soil conditions with four replicates. The genera Glomus, Claroideoglomus, and Aculospora were identified as the most common AMFs in paddy soil in all investigated sites. In the 9th week of sampling, AMF root colonization was positively correlated (p = 0.028) with spore density. In Sri Lanka, for the first time, the highest AMF colonization rates in rice were recorded at 36.40% in the roots of the Bg350 from the Gampaha district. AMF root colonization increased over sampling time and was different according to the interactive effect of fertilizer application and soil condition. The biometric parameters and yield-attributing characteristics were significantly higher in the rice plants grown in sterilized soil, independent of the tested treatments. The number of grains per panicle was significantly similar (p ≤ 0.05) in the compost, AMF-biofertilizer, and inorganic fertilizer added treatments. It can be concluded that application of paddy soil adapted AMF species as a biofertilizer increased rice plant growth, productivity, and yield.
