LEDA (Eucalyptus Deglupta Blume) Increment on Various Dimensions of Growth

Abstract

Setting stands to produce the optimal growth of Leda (Eucalyptus deglupta Blume) is necessary to achieve maximum and sustenable results. The study aims to determine the growth and accretion of growth (increment) of Leda (Eucalyptus deglupta Blume) stands. The research was conducted in the area of Industrial Forest Plantation Inhutani Company Gowa-Maros, South Sulawesi, on Leda stands aged 1 year, 2 years, 3 years, 5 years, and 7 years. The research was conducted using survey methods and purposive sampling techniques that chose age-class stands at the research site. The data was gathered through the 15 sample plots, each measuring 0.04 ha (20 x 20 m), by striving in a particular way so that the sample plot represents the growth conditions of the stand. The growth analysis of the Leda stands used Richard’s Model equation, which was then extrapolated to obtain the increment values of CAI and MAI at the dimensions of height, diameter, and area of the based area. The results showed that the growth of the 7-year-old Leda reached a height of 17.20 m, with a Mean Annual Increment (MAI) of 2.46 m and a Current Annual Increment (CAI) of 2.00 m. The diameter of the 7-year-old Leda’s trunk reached a diameter of 14.60 cm, with a Mean Annual Increment (MAI) of 2.09 cm and a Current Annual Increment (CAI) of 2.30 cm. The basal Area (BA) of 7-year-old Leda reached 15.6 cm². The mean accretion of the based area (MAI) was 2.23 cm², and the annual accretion of the based area (CAI) was 2.40 cm². The diameter of the 10-year-old Leda’s trunk reached tree level with a trunk diameter of 21.1 cm.
