This study was conducted in the Department of Biology / College of Science / University of Babylon / Iraq, to evaluate the effect of copper nanoparticles and magnetized salty water in some physiological and biochemical characteristics of tomato (Lycopersicon esculentum Mill). The total number of treatments was 144 (48 treatments with 3 replicates per treatment) for the seasons (2018-2019) and (2019-2020), and this study included: _The laboratory experiment (the dish experiment). This study was including planting 20 seeds in each dish. The results of this study showed that the effect of single factors (nanoparticles, magnetized water and salinity), the interaction between (salinity and magnetic water; nano.Cu and salinity; magnetic water and nano.Cu) and triple interaction (salinity, magnetic water, and nano.Cu) on the percentage of germination, percentage velocity germination, radical length, fresh and dry weight of the radical in tables (2, 3, 4, 5 and 6) respectively, and a decreasing significantly of the percentage of germination, percentage of germination velocity coefficient, radical length and fresh and dry weight of the radical by increasing the single factors and secondary interaction between factors and also increasing the triple interaction of factors. The field experiment (the pots experiment): _at the winter season 2018-2019 from the date of 2/12/2018 where the plants were transferred from the seedlings (60-day age) to the plastic pots (capacity 1.5 kg, diameter 20 cm) to the date 2/4/2019 until the fruiting season at about 120 days of age, the overall number of pots at 144 (48 treatments and 3 replicates per treatment). Physiologically, the results of this experiment were shown that the effect of single factors and secondary interactions between factors and the triple interaction of factors on the dry weight of the shoot and root, the length of the shoot, stem diameter and number of flowers in tables (7, 8, 9, 10 and 11), respectively, recorded a significant increase for the dry weight of the shoot and root, shoot length, stem diameter, and a decreasing significantly of the number of flowers, by increasing of salinity, magnetic water, and nano.Cu, the dry weight of root and shoot was increasing significantly at the interaction between salinity and nano.Cu, also, a significant increasing in the dry weight of the root and shoot at the interaction between (salinity, magnetic water and nano.Cu). The results also showed that shoot length and stem diameter were increasing significantly and the number of flowers was decreasing significantly at the interaction between (salinity and magnetic water, salinity and nano.Cu, magnetic water and nano.Cu), the dry weight of shoot and root was increasing significantly at the triple interaction of factors, while the number of flowers was decreasing significantly at the triple interaction of factors. Biochemically, the results showed that the effect of single factors, secondary interaction and triple interaction between factors on each of chl.a, chl.b, carotenoids and total chlorophyll in tables (12, 13, 14 and 15) was recorded an increasing significantly of chl.a, b and total chlorophyll by increasing the salinity, magnetized water and nano.Cu and increasing significantly at the interaction between (salinity and magnetic water; salinity and nano.Cu; magnetic water and nano.Cu), in addition of the triple interaction that, chl.a was increasing significantly at the interaction between river water E.C 2.83 dSm-1 and 5 mg/L for nano.Cu, and a decreasing significantly at the interaction between tap water E.C 1.3 dSm-1 and 5 mg/L for nano.Cu, and there was a significant increasing for chl.b when the interaction between the drainage water E.C 7 dSm-1 and 2000 Gauss, and a significant increasing in total chlorophyll at the triple interaction (salinity, magnetic water and nano.Cu). The carotenoids, these were increasing significantly by increasing of salinity and magnetic intensity, and decreasing significantly by increasing of nano.Cu, also, the carotenoids increasing significantly at the interaction between (salinity and magnetic water, salinity and nano.Cu, magnetic water and nano.Cu), and they significantly increased at the interaction between the drainage water E.C 7 dSm-1 and 3000 Gauss with 5 mg/L for nano.Cu. And the results were shown the effect of the single factors and the secondary and triple interaction between these factors on catalase and superoxide dismutase activity in tables 16 and 17 respectively, CAT and SOD activity was increasing significantly by increasing salinity, magnetic water, and nano.Cu as well as during the interaction between salinity and nano.Cu, and CAT activity was decreasing significantly in the interaction between the magnetized water and nano.Cu, while SOD activity was increasing significantly at the interaction between the magnetized water and nano.Cu at the triple interaction, while CAT activity was increasing significantly in the interaction between the drainage water E.C 7 dSm-1 and 5 mg/L for nano.Cu, and decreasing significantly at the interaction between river water E.C 2.83 dSm-1 and 9 mg/L for nano.Cu, and SOD activity was increasing significantly in the interaction between the drainage water E.C 7 dSm-1 and 5 mg/L of nano.Cu while the significant reduction in the interaction between the tap E.C 1.3 dSm-1 and 0.5 mg/L for nano.Cu. The effect of the single factors, the secondary and triple interaction between the factors on glutathione and proline content in tables 18 and 19 respectively, the results were shown that these were an increasing significantly in GSH content by increasing the magnetic intensity and a decreasing significantly by increasing of salinity and nano.Cu, as well as an increasing significantly at the interaction between salinity and magnetized water and the interaction between salinity and nano.Cu, while there was a decreasing significantly of GSH content at the interaction between nano.Cu and magnetized water, as well as a decreasing significantly at the triple interaction of factors, as for the proline content, the results were recorded a decreasing significantly by increasing of salinity, magnetized water and nano.Cu, and a significant increase at the interaction between salinity and magnetic water, and the interaction between salinity and nano.Cu, while the proline content was decreasing significantly at the interaction between the magnetic water and the nano.Cu, the proline content was decreasing significantly at the triple interaction of factors.
