Impact of Sodium Hypochlorite Applied as Nutrient Solution Disinfectant on Growth, Nutritional Status, Yield, and Consumer Safety of Tomato (Solanum lycopersicum L.) Fruit Produced in a Soilless Cultivation

Soilless crop production is spread worldwide. It a cultivating technique that enhances yield quality and quantity, thus contributing to both food safety security. However, in closed-loop soilless crops, the risk of spreading soil-borne pathogens through recycled nutrient solution makes establishment disinfection strategy necessary. In current study, sodium hypochlorite was applied as chemical disinfectant assess its impact on plant growth, leaf gas exchange, fruit yield, tissue mineral composition, possible accumulation chlorate perchlorate residues tomato fruits. The application 2.5, 5, 7.5 mg L−1 chlorine three times at fortnightly intervals during cropping period had no growth or exchange parameters. Furthermore, 2.5 led significant increase total marketable fruits (total weight per plant). No consistent differences concentrations were recorded between treatments. Moreover, neither nor detected fruits, even though present solution. Therefore, obtained tomatoes safe for consumption. Further research needed test combination with inoculation efficiency solutions.
