Growing leafy vegetables in Nutrient Film Technique (NFT) hydroponic systems under a range of saline water with the use of Nanobubbles

Abstract

This specific experiment was carried out with the aim of investigating the effect of different salinity levels on hydroponic lettuce cultivation NFT, in combination with nanobubble and MaxGrow technologies. The experiment consisted of six different treatments with different salinity levels with EC from 1-12ds / m. During the research, measurements were made, such as the temperature of the environment and the solution, the PAR, the Ph, EC and the dissolved oxygen in the solutions. The results of our research showed that high salinities negatively affected the biomass yield, however, with the use of the technologies, a reduction in plant stress was observed at high salinities. This research highlights that the use of hydroponic systems in combination with MaxGrow systems and nanobubbles can play an important role in the cultivation of various species, especially in areas where there is high salinity in irrigation water.
