Abstract

Tapping panel dryness (TPD) is well known as brown inside bark (bruine binnen bast atau brown bark atau bark dryness atau brown bast) which shortened BB disease that difficult to be recovered. This research was aims to know the healing level of partial as well as tapping panel dryness and total tapping panel dryness that applied with some compound biofertilizers.Two separate experiments were done, first on partial TPD and second on total TPD. Each experiment was arranged in randomyzed complete block design.Four formulas of liquid compound fertilizers were used in the experiments the extract of fish waste fermentation, Biofitalik, Biofitalik + 5% NaCl, and Biofitalik + 5% KCl. The fertilizer was applied by spraying directly to the tapping panel (without bark scrapping) twice with one-month-interval. Each formula was sprayed to 10 trees as replication. Non-treated diseased trees were subjected as control. The result show that spraying ofcompound biofertilizer to the partial TPD treess harply increased the latex volume and lump weight, but did not decrease stoppage index. The increasing of latex volume and lump weight was slightly observed when applied to the total TPD tress.
