Abstract

The objective of this study was to investigate the effects of electrical conductivity and micro/nanobubbles (MNBs) in nutrient solution culture under a hydroponic system on growth and yield of cherry tomatoes. The experiment was assigned using a 3x2 factorial arrangement in a completely randomized design. Factors were factor A, with three levels of electrical conductivity (EC) at 1, 2, and 3 mS/cm in the nutrient solution of the hydroponic system, and factor B, with two levels MNBs, including with or without the application of MNBs, respectively. The cherry tomato seedling was grown in a deep-flow technique (DFT) hydroponic system. The experiment was conducted in a greenhouse environment from July to October 2021 at the Agricultural Technology Research Institute, Rajamangala University of Technology Lanna, Lampang, Thailand. The results showed that the EC levels and MNBs did not increase plant height, inflorescence, leaf number per shoot, and leaf size. However, increasing EC from 1 to 2 mS/cm enhanced leaf greenness and chlorophyll fluorescence. On the other hand, the EC at 2 mS/cm with MNBs was the most effective, in particular on fruit size, fruit weight, and yield. Additionally, EC at 3 mS/cm with MNBs improved the total soluble solids of cherry tomato fruits. Results from this experiment suggest that levels of electrical conductivity and micro/nanobubbles have the potential to enhance growth, yields, and fruit quality of cherry tomatoes.
