Abstract

The aim of this research is to obtain a method to accelerate vegetative growth through the provision of nutrient solutions using a planting media immersion system (tach system). This research was conducted in the Greenhouse from July to October 2023. This research uses a factorial Randomized Block Design (RBD). The first factor is the frequency of immersion (F) with 3 levels, and the second factor of chicken manure concentrate (C) consists of 2 concentrations. The results showed that the treatment of soaking frequency and nutrient concentration had a significant interaction effect. The results of the regression test showed a linear interaction pattern for all growth variables, except leaf area. The more often you soak the planting medium, the better the growth of the Phalaenopsis amabilis. This shows that plant media soaked in nutrient solution cannot absorb dissolved nutrients for a long time. Based on these results, it was concluded that the more frequent immersion of the planting medium in nutrient solution had a positive effect on the growth of orchid plants. However, this research also shows that although statistically the effect of different treatments is significant on the growth variable, it is not visually obvious.
