<![CDATA[Analysis of the Effect of Rainfall on the Productivity of Oil Palm (Elaeis guineensis Jacq.) in High-Rainfall Environments in Sei Dadap District, Asahan District, North Sumatra. Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's main plantation commodities, and its productivity is influenced by various environmental factors, including rainfall. Rainfall plays a crucial role in meeting plants' water needs to support growth, photosynthesis, and fruit formation. However, excessive rainfall can cause negative impacts such as erosion, nutrient leaching, waterlogging, damage to plantation infrastructure, and obstacles in maintenance and harvesting activities. Sei Dadap District, Asahan Regency, North Sumatra, has relatively high rainfall levels. Based on data from 2020–2025, the average annual rainfall reaches around 3,589 mm, higher than the optimum requirement for oil palm plants, which ranges from 2,000–2,500 mm per year. This study aims to examine the effect of rainfall on oil palm productivity in Sei Dadap District. The results are expected to clarify the relationship between rainfall and oil palm productivity, providing a basis for more effective plantation management in high-rainfall areas.]]>
