Abstract:
Research objective: The aim of this research was to evaluate the stimulating potential of a product (FertilTomix) obtained by an innovative extraction process from seawater with the addition of silver, copper and zinc on aubergine and cucumber plants. In addition, it was assessed whether the product improves the nutritional quality of the fruit.
Materials and Methods: The experiments, which started in May 2024, were conducted in the CREA-OF greenhouses in Pescia (Pt), on aubergine (Solanum melongena L.) and cucumber (Cucumis sativus). Plants were placed in pots of ø 14 cm, 30 plants per thesis, divided into three replications of 10 plants each. The experimental groups were: i) control group; ii) conmmercial biofertilizer; iii) FertilTomix; iv) FertilTomix with added silver, copper and zinc. On 10 September 2024, plant height (aubergine), length of the central branch (cucumber), number of leaves, leaf area, vegetative weight, root volume, number and weight of fruits were determined. The nutritional properties of the fruits were also assessed, for aubergine (iron, calcium, sodium, potassium, phosphorus, zinc, riboflavin thiamnine, vitamin C, niacin, vitamin B6, folate) and for cucumber (potassium, phosphorus, calcium, magnesium, sodium, iron, pantothenic acid, pyridoxine, zinc, manganese, vitamin C, niacin, riboflavin, vitamin E, thiamine, vitamin K, folate).
Results and Discussion: The experiment showed that the use of FertilTomix, can significantly increase the height, number of leaves, vegetative and root growth, and leaf area of aubergine and cucumber plants. The product FertilTomix with added silver, copper and zinc worked better than as such, stimulating plant growth more. The trial also showed an increase in the number and weight of fruits in both aubergine and cucumber, in the theses treated with FertilTomix compared to the control and the commercial control with algae. The leaves also appeared larger and more intensely green in the theses treated with minerals extracted from the sea. The analysis of the mineral and vitamin content of the fruits showed a significant increase in minerals and vitamins in the fruits treated with FertilTomix for most of the analysed parameters, to a greater extent with FertilTomix with added silver, copper and zinc
Conclusions: Various extracts obtained from seawater using an innovative mineral process were found to significantly increase plant growth. The test also showed an increase in the mineral and vitamin content of the fruit, probably influenced by the increased presence of bacteria in the soil, in the theses treated with marine extracts, as demonstrated in other tests with the same product. As well as for those wishing to reduce the use of industrial fertilisers, the results obtained are particularly interesting for those growing in arid environments or those without drinking water
