This experiment determines the effect of nitrogen and potassium concentrations combined with photoperiod on Viola growth in a plant factory to enhance product quality and reduce production time.
The objective of this experiment was to determine the effect of nitrogen and potassium concentration combination with photoperiod on the growth of Viola in a plant factory to increase the quality of the products, reduce the production time and increase the production cycle throughout the year. The experimental plan was 3x3 Factorial in CRD with nine treatments and three replications. The study focused on two factors:
- Factor 1: Three different concentrations of nitrogen and potassium in ratios of 1:1, 1:2 and 2:1.
- Factor 2: Different photoperiods (24-hours, 8-hours light/16-hours dark, and 5-hours light/3-hours dark).
The result showed that the concentration of N:K in the ratio of 1:1 combined with 24-hour photoperiod maximized vegetative and reproductive growth. This treatment reduced the production cycle from 90-100 days down to 43-45 days, allowing for year-round production.
Objective
To determine the optimal nitrogen and potassium concentrations and photoperiod for the growth, quality, and production cycle of Viola in a plant factory.
To determine the optimal levels of nitrogen and potassium concentration combined with the appropriate photoperiod for:
- Growth of Viola plants.
- Product quality.
- Production time per cycle.
- Total production cycles of Viola under plant factory conditions.
