Abstract

The objective of this study was to evaluate the effect of different nutrient solution spraying rates (open/close duration) in an aeroponics system. The spraying rates tested were as follows: 1) 1 min/3 min, 2) 1 min/5 min, and 3) 1 min/7 min, continuously applied in a greenhouse measuring 1.38 × 2.00 × 2.32 m (width × length × height). The average temperature and relative humidity inside the greenhouse were 28.20°C and 65.50 %, respectively. The experiment followed a completely randomized design (CRD) with four replications per treatment. Results showed that the green oak lettuce exhibited the most significant growth parameters when the nutrient solution spraying rate was set at 1 min/3 min, with an average leaf number of 33.38 ± 1.01, plant height of 10.50 ± 0.85 cm, shoot fresh weight of 69.96 ± 3.58 g, shoot dry weight of 3.45 ± 0.11 g, root fresh weight of 19.09 ± 0.39 g, and root dry weight of 0.98 ± 0.02 g. Additionally, the green oak lettuce displayed the highest plant canopy height (20.25 ± 0.25 cm) and root length (73.50 ± 1.66 cm) when the nutrient solution spraying rate was set at 1 min/5 min.
