    Contemporary agriculture faces increasing challenges related to sustainability, food security, and mitigation of environmental impacts. In this context, the tomato plant (Solanum lycopersicum L.), a vegetable crop of great economic and social relevance, serves as an ideal model for studies on plant-microorganism interactions. The objective of this dissertation was to evaluate the effects of applying effective microorganisms (EMs), particularly in the form of liquid bokashi/Tomita Microorganisms Technology (TMT), on the growth, yield, and fruit quality of tomato plants, also considering their interaction with arbuscular mycorrhizal fungi (AMF). The first article presents a systematic review, conducted according to the PRISMA protocol, which identified 2,450 records and included 31 studies. These studies demonstrate the benefits of the co-inoculation of AMF and EMs, such as increased phosphorus uptake, enhanced biomass accumulation, tolerance to abiotic stresses, suppression of pathogens, and improvements in fruit quality. The second article describes an experiment conducted under controlled conditions, using a completely randomized design (CRD) with seven treatments, in addition to a control, to evaluate different rates and application frequencies of the product associated with NPK 10-10-10 mineral fertilization. Treatments T1 (50 L ha⁻¹), T2 (100 L ha⁻¹), T3 (200 L ha⁻¹), and T7 (400 L ha⁻¹) received a single application, while treatments T4 (50 L ha⁻¹), T5 (100 L ha⁻¹), and T6 (200 L ha⁻¹) received two applications at the same rate. The control received no application of the product. The evaluated variables included vegetative growth parameters (plant height, leaf number, leaf area), fresh and dry biomass accumulation, yield (fruit number and weight), and quality parameters (soluble solids content, firmness, and color). The results demonstrated that split application of TMT promoted a significant increase in plant height (up to 22% compared to the control), leaf area (average increase of 18%), dry biomass accumulation (25% increase), and yield (20% increase in both fruit number and weight). In contrast, single application concentrated effects on vegetative growth, without significant gains in reproductive output. It is concluded that the use of effective microorganisms, associated with mycorrhizal symbiosis, represents a promising strategy to strengthen tomato cultivation in sustainable agricultural systems, reducing the need for synthetic fertilizers and pesticides while reconciling productivity, quality, and environmental conservation in line with the principles of regenerative agriculture.
