Chemical methods to grow and improve plants threaten the health of the environment. In a previous study, factors assuming that flavonoids properties for instance pH, temperature, time, and plant extract content were assayed. Tomato (Solanum lycopersicum) is the second most important vegetable in the world in terms of its economic value. This experiment was conducted in a completely randomized block design with three levels of chitosan, sylamol, aqueous extract, and silver nanoparticles with three replications. Different concentrations of silver nitrate solution (10, 20, 30mg/ l), aqueous extract (10, 20, 30mg/ l), chitosan (0.1, 0.3, 0.5 v/v) and silamol (1/1000, 2/1000, 3/1000(v/v) and control treatment (distilled water) were applied. Nutritional content including lycopene, Total soluble solids concentration (TSS), vitamin C, zinc, iron, magnesium, phosphorus, calcium, and potassium. Factors assuming that flavonoids properties for instance pH, temperature, time, and plant extract content were assayed., Fe, Mn, P, Ca and K, are significantly affected by using treatment. Measurement of features was done at 4, 1, 3, 7, and 11 days. The results showed that the application of the above treatment at 30 ppm silver nanoparticles was more effective than all other nutritional characters. So, these natural matters could be used for increasing the quality of tomatoes.
