Abstract Phosphorus (P) is a macronutrient that plants need to grow. However, most of the soil’s phosphorus still insoluble, making it difficult for absorb. This creates barrier ecologically responsible farming methods and calls innovative approaches solubilization. Solublizing microorganisms improve availability phosphorous in soil. The term “phosphorus-solubilizing microorganisms” (PSMs) describes various fungi or bacteria divide into more soluble forms. It shows how PSMs interact with their processes solubilize phosphorus. Soil pH, temperature, nutrient are only few parameters affecting its activity. investigated potential increase plant absorption use, thereby boosting agricultural yield usage efficiency. use effects on environment also evaluated. By using PSMs, farmers may less chemical fertilizers contribute runoff eutrophication waterways. Furthermore, soil structure, decrease losses, cycling, all which health long-term viability systems. Phosphorus-solubilizing have enormous promise environmentally land management. Better availability, greater output, pollution, better possible outcomes PSMs. further study required determine best application strategies, formulations, choices Incorporating operations can potentially environmental sustainability resilience. article will explore addressing critical challenges, including erosion, runoff, sustainable practices, resource conservation.

Phytopathogenic nematodes are a threat for agriculture, they cause plant diseases and economic losses worldwide. Currently, the pursuit of compounds biological origin nematode biocontrol has become priority as an environmentally friendly alternative. Microorganisms-derived have several strategies to reduce populations infectious juvenile nematodes. Although microorganisms their metabolites focus literature reports reviews on nematicidal control, interactions between fungi, bacteria, nematodes, well that generated in such interactions, not highlighted. The aim this review was discuss latest advances chemical secreted by interaction mechanisms control phytopathogenic Results were organized based on: i) mode action, ii) infection process, iii) nematicide compounds, iv) field applications, v) current challenges. scope contributes better comprehension versatility bacterial fungal use development management plans control.

Multifarious Characterization and Efficacy of Three Phosphate-Solubilizing Aspergillus Species as Biostimulants in Improving Root Induction of Cassava and Sugarcane Stem Cuttings

Plants, Journal Year: 2023, Volume and Issue: 12(20), P. 3630 - 3630

Published: Oct. 20, 2023

Several soil fungi significantly contribute to the enhancement of plant development by improving nutrient uptake and producing growth-promoting metabolites. In present study, three strains phosphate-solubilizing fungi, namely, Aspergillus chiangmaiensis SDBR-CMUI4, A. pseudopiperis SDBR-CMUI1, pseudotubingensis SDBR-CMUO2, were examined for their plant-growth-promoting capabilities. The findings demonstrated that all showed positive siderophore production, but only can produce indole-3-acetic acid. All able solubilize insoluble phosphate minerals [Ca3(PO4)2 FePO4] phosphatase enzymes organic acids (oxalic, tartaric, succinic acids). These fungal species grown at a water activity ranging from 0.837 0.998, pH values 4 9, temperatures between 40 °C, 16–17% NaCl in order evaluate drought, pH, temperature, salt tolerances, respectively. Moreover, results indicated tolerate commercial insecticides (methomyl propargite) recommended dosages field application. viability each strain inoculum was higher than 50% 20 °C after 3 months storage. Subsequently, characterized as root inductions cassava (Manihot esculenta Crantz) sugarcane (Saccharum officinarum L.) stem cuttings greenhouse experiments. No symptoms disease observed with any treatments involving inoculation control. inoculated supplemented Ca3(PO4)2 exhibited increased lengths, shoot dry biomasses, chlorophyll concentrations, cellular inorganic contents. Therefore, application these is regarded new frontier induction roots promotion growth plants.
