Patchouli plants (Pogostemon cablin) in Batu Putih Village often die from erratic seasons. Excess soil water content during the rainy season causes plants to rot and die, while a lack of water content also leads to plant death. This study aimed to determine the effect of soil water content on the growth of patchouli (Pogostemon cablin) in Batu Putih Village, Batu Putih District, and North Kolaka Regency. A randomized block design (RBD) method was used with two treatment factors: material type and groundwater concentration. The results showed that watering with 100% groundwater concentration (500 ml) gave the best growth compared to 60% and 40% concentrations. However, the ANOVA test indicated that watering with different concentrations did not have a significant effect on plant growth, suggesting that water may not be the dominant factor in patchouli growth.

The study concluded that varying groundwater concentrations did not significantly impact the growth parameters of patchouli plants.This suggests that factors beyond water availability, such as nutrient content or genetic predisposition, may play a more dominant role in patchouli growth in the study area.Further research is needed to investigate these other factors and their interactions with water content to optimize patchouli cultivation practices.

Based on the findings, future research should investigate the influence of soil nutrient levels, particularly nitrogen and phosphorus, on patchouli growth, as these may interact with water availability. Additionally, a study exploring the genetic diversity of patchouli varieties grown in Batu Putih Village could identify strains more resilient to fluctuating water conditions. Finally, a long-term experiment examining the combined effects of water management strategies, nutrient supplementation, and different patchouli varieties on oil yield and quality would provide valuable insights for improving patchouli cultivation practices and ensuring sustainable production in the region. These investigations should involve a comprehensive analysis of soil composition, plant physiology, and environmental factors to provide a holistic understanding of patchouli growth dynamics and inform effective agricultural interventions.
