In the process of growth and production of duku, environmental and soil factors are very influential including pH, C-organic, Nitrogen (N), Phosphorus (P) and Potassium (K). The purpose of this study was to find out the suitability class of land for duku plants at two locations of duku plants based on age. The research was conducted by sampling of soil in two locations, namely Rasuan Village of OKU Timur and Ujan Mas of Muara Enim with the grouping of the age of duku plants under 25 years, between 25-49 years, 50-75 years and over 75 years. The results shows that the suitability of land for duku plant in Rasuan Village is more suitable than in Ujan Mas Village. The suitability of land in Rasuan Village is indicated by higher soil pH, C- Organic, N Total, and K values than in Ujan Mas Village. The age of the plant also affects the biological C-Organic and P<sub>2</sub>O<sub>5.</sub></p>}, number={1}, journal={BIOVALENTIA: Biological Research Journal}, author={Juairiyah, Oktaf and Bernas, Siti Masreah and Yustian, Indra}, year={2022}, month={Feb.}, pages={46–50} }
