VUELTA-LORENZO, Daniel Rafael et al. Irrigation with Magnetically Treated Water on Tomato (Solanum lycopersicum L.) Inoculated with Arbuscular Mycorrhizal Fungi. Rev Cie Téc Agr [online]. 2023, vol.32, n.4  Epub 29-Nov-2023. ISSN 2071-0054.

The aim of the study was to determine the effect of magnetically treated water (ATM) with a stationary magnetic field on the yield of tomato (Solanum lycopersicum L.) inoculated with three strains of arbuscular mycorrhizal fungi (AMF) infested with the nematode Meloidogyne incognita (Kofoid and White) Chitwood. The investigation began in a soft brown soil without carbonate, in the “Campo Antena” Protected Cultivation Unit, belonging to “América Libre” Socialist State Enterprise; between November 2018 and February 2019. The inoculation of the microorganisms was carried out at the time of the transplant, in a proportion of 10% with respect to the volume of the root ball. The experimental design was completely randomized blocks, with 8 treatments and four replicas, with a control without AMF inoculation, a treatment without AMF inoculation and irrigation with magnetically treated water, 3 treatments with inoculation with Glomus cubense, Rhizophagus irregularis, Fummeliformis mosseae, and 3 treatments with the inoculation of these 3 AMF species combined with irrigation with magnetically treated water with an induction of 0.07 T. The data obtained were processed in the statistical package R Commander by means of a simple analysis of variance, applying Duncan's Test of mean multiple comparison for p≤ 5. The results obtained showed the efficiency of the treatments applied in tomato yield, highlighting the treatment with G. cubense and ATM, which yielded 112.9 t·ha-1 and provided greater protection to the plant against the nematode attack by reducing the galling index to 1.
