“…Generally, combined inoculation of Rlp and cyanobacteria extracts showed a significant increase in plant height (cm), root length (cm), fresh and dry weight (g plant -1 ) compared to inoculation with Rhizobium individually ( Figure 5). The same results were observed by Abdel-Monaim et al (2016) who showed that lupine seeds treated with cyanobacteria extracts recorded the highest protection against infection with soil-borne pathogens and significantly improved plant growth and yield parameters under field conditions.

“…Pots were irrigated weekly till the field capacity. For cyanobacterial extracts treatments, the seeds were dipped before planting for 12 hours in previously prepared cyanobacterial extracts as described by Abdel-Monaim et al, (2016) at the same concentration (250 μg ml -1 ). Subsequently, bean plants were foliar sprayed with 10 ml of the cyanobacterial extracts four times with two weeks interval and the first foliar treatment was done three weeks after transplanting as described by Tassara et al, (2008).…”

Recently, the chloroform extraction of the red algae Gracilaria confervoides was the most efficient against R. solani on cucumber plants, followed by ethyl acetate extraction (Soliman et al 2018).…”

In this study, laboratory and greenhouse experiments were conducted to investigate the suppression effect of two biocontrol agents caynobacterial (Spirulina sp., Nostoc linckia and Anabaena variabilis) extracts, along with Rhizobium leguminosarum biovar phaseoli, against Sclerotinia sclerotiorum in common bean plants. Four isolates of S. sclerotiorum were tested for pathogenicity in bean plants, and all isolated fungi proved to be pathogenic and caused white rot symptoms. Results of in vitro studies showed that algal extracts significantly inhibited the mycelial growth of the pathogen when compared to the untreated control. N. linckia gave the highest reduction (56.29%), followed by A. variabilis (51.85%) and Spirulina sp. (45.93%), respectively compared to control (0%). In greenhouse experiments, the combined effect of Rhizobium sp. and cyanobacterial extracts significantly reduced disease incidence and severity under artificial infection with S. sclerotiorum. The treatments showed the maximum effects for controlling disease incidence and severity caused by S. sclerotiorum, which were in the range of 13.33 to 26.67 % and 1.24 to 1.82, compared to 73.33 and 4.50 % in infested control, respectively. In addition, these treatments increased number of nodules, plant height, root length, fresh and dry weight of shoots, N2 % and total nitrogen compared to control. The effects were similar to those of the fungicide Vitavax, which reduced the disease incidence and severity but adversely affected Rhizobium sp. and the symbiotic N2 fixing parameters. Considerable increases in activity of oxidative reductive enzymes (peroxidase and polyphenol oxidase) were recorded in plants grown from treated bean seeds.

Aerobes and phototrophs as microbial organic fertilizers: Exploring mineralization, fertilization and plant protection features

et al. 2022

View full text Add to dashboard Cite

Organic fertilizers and especially microbial biomass, also known as microbial fertilizer, can enable a paradigm shift to the conventional fertilizer-to-food chain, particularly when produced on secondary resources. Microbial fertilizers are already common practice (e.g. Bloom® and Synagro); yet microbial fertilizer blends to align the nutrient release profile to the plant’s needs are, thus far, unexplored. Moreover, most research only focuses on direct fertilization effects without considering added value properties, such as disease prevention. This study has explored three promising types of microbial fertilizers, namely dried biomass from a consortium of aerobic heterotrophic bacteria, a microalga (Arthrospira platensis) and a purple non-sulfur bacterium (Rhodobacter sphaeroides). Mineralization and nitrification experiments showed that the nitrogen mineralization profile can be tuned to the plant’s needs by blending microbial fertilizers, without having toxic ammonium peaks. In a pot trial with perennial ryegrass (Lolium perenne L.), the performance of microbial fertilizers was similar to the reference organic fertilizer, with cumulative dry matter yields of 5.6–6.7 g per pot. This was confirmed in a pot trial with tomato (Solanum lycopersicum L.), showing an average total plant length of 90–99 cm after a growing period of 62 days for the reference organic fertilizer and the microbial fertilizers. Moreover, tomato plants artificially infected with powdery mildew (Oidium neolycopersici), a devastating disease for the horticultural industry, showed reduced disease symptoms when A. platensis was present in the growing medium. These findings strengthen the application potential of this novel class of organic fertilizers in the bioeconomy, with a promising match between nutrient mineralization and plant requirements as well as added value in crop protection.
