Introduction

The oil palm industry is one of the most significant contributors to the economy of many countries, particularly in Southeast Asia. However, the industry is facing numerous challenges, including the spread of diseases such as stem rot caused by Ganoderma sp. This disease can cause significant losses in terms of economic and environmental sustainability. One of the factors that can affect the severity of this disease is the availability of nutrients, especially potassium (K), which has an important role in the process of photosynthesis, root formation, and plant resistance to disease.

Background

Stem rot disease caused by Ganoderma sp. is one of the serious problems that can threaten the productivity of oil palm plantations. This disease can cause significant losses, both in terms of economic and environmental sustainability. The disease is characterized by the rotting of the stem of the oil palm tree, which can lead to the death of the tree. The disease is caused by the fungus Ganoderma sp., which can infect the tree through wounds or natural openings.

Methodology

This study aims to determine the distribution of potassium (K) nutrients and their interactions with the intensity of stem rot disease caused by Ganoderma sp. In oil palm plantations at PT. PD Pati, Aceh Tamiang. The study was conducted at the Socfin Indonesia Laboratory in North Sumatra and Laboratory Biology of Soil, Faculty of Agriculture, University of North Sumatra, Medan, from May to September 2015. Soil sampling was carried out using the Purposive Proportional Random Sampling method and nutrient extraction analysis was carried out using HCl 25 % K2O. Furthermore, the nutrient status map was made to provide a clear picture of the distribution of nutrients. The data obtained is processed using correlation and regression analysis using SPSS Statistics 20.0 software.

Results

The results showed that there was a real correlation between the intensity of stem rot (Ganoderma sp.) With the availability of K and organic carbon content (C-organic). From the analysis, it can be concluded that the intensity of stem rot is influenced by the availability of K and C-organic, which can be expressed in the equation Y = 0.779 + 30.146x1 + 0.007x2. Where Y is the intensity of the disease, X1 is K-Available, and X2 is C-organic.

Discussion

The results of this study indicate that the availability of K and C-organic content are important factors that influence the intensity of stem rot disease caused by Ganoderma sp. in oil palm plantations. The availability of K is essential for the process of photosynthesis, root formation, and plant resistance to disease. The C-organic content is also important for the health of the soil and the plant. The results of this study support the importance of mapping the status of nutrients on oil palm land.

Conclusion

In conclusion, this study highlights the importance of survey and mapping of nutrients on oil palm land that is attacked by Ganoderma sp. The study shows that the availability of K and C-organic content are important factors that influence the intensity of stem rot disease caused by Ganoderma sp. in oil palm plantations. The results of this study support the importance of mapping the status of nutrients on oil palm land and provide guidance for farmers in making appropriate fertilization.

Recommendations

Based on the results of this study, the following recommendations are made:

  • The manager of oil palm plantations should take preventive and remedial measures to Ganoderma sp. by increasing the status of Nutrients K and C-organic in their land.
  • The use of statistical methods such as correlation and regression analysis should be used to provide clarity about the factors that influence each other.
  • The results of this study should be used as a reference for the manager of oil palm plantations to take preventive and remedial measures to Ganoderma sp.

Future Research

Future research should focus on the following areas:

  • The effect of other nutrients on the intensity of stem rot disease caused by Ganoderma sp.
  • The use of other statistical methods to provide clarity about the factors that influence each other.
  • The development of a more effective management strategy to reduce the impact of the disease.

Limitations

This study has several limitations, including:

  • The study was conducted in a limited area and may not be representative of other oil palm plantations.
  • The study only focused on the availability of K and C-organic content and may not have considered other factors that influence the intensity of stem rot disease caused by Ganoderma sp.
