MODEL PERTUMBUHAN DAN HASIL TANAMAN Shorea leprosula PADA SISTEM TEBANG PILIH TANAM JALUR TEKNIK SILIN

Abstract

The Intensified Selective Logging and Lined Planting (ISLLP) silvicultural system can be applied in the logged over forest and low potential forest to improve their productivity. The research was aimed to create modelling of growth and yield of Shorea leprosula plantations in the ISLLP system. The research was conducted at research plots of ISLLP in logged over forest of PT. Gunung Meranti, Central Kalimantan Province. The research plots were divided into three plots of Shorea leprosula plantation that planted in 1994 as plot 1, year 1999 as plot 2 and year 2008 as plot 3 in which consisted of 200 samples of trees, respectively. Data of Shorea leprosula growth were evaluated by Stella 9.0.2 and SPSS 13, and predicted using table of volume and polynomial equations. The research result showed that group polynomial equations estimated cutting cycle at 2 32 years old with R value of greater than 95%.
