Development of Gmelina arborea under the Subri Conversion Technique: first three years.
1994
Nwoboshi, L. C.
The Subri conversion technique is a new site preparation technique in West Africa in which degraded natural forests are cleared, and lines are cut through the debris and planted up without any burning. Under these conditions the humus layer and the extra debris on the forest floor are conserved. Data are reported on the survival, growth and biomass production of 2- and 3-yr-old plantations Gmelina arborea raised using this technique. Survival was 75 to 83%, mean height 12 and 15 m, mean diameter 12 and 14 cm, and volume 73 and 170 m3/ha, respectively, at 2 and 3 yr old; biomass production was 40 and 56 t/ha, with the stem as the dominant component. The potential crop trees grew much faster, with mean annual increment (MAI) in height of 6.4 and 5.70 m and in diameter of 7.3 and 6.3 cm in the 2nd and 3rd years respectively.
