Abstract. Nowaday the role of genetic and environment factors on latex production have widely revealed by some researchers, but lack on the wood production wood especially for the effect of land elevation and slope exposition direction against solar beam radiation so need to research. Ordinary Least Square employed at 90% significant level, the respond variable was the volume wood production per tree, [WOOD], whereas the predictor were land elevation in an-100 m above sea level [ELV], land slope expositions that were decomposed into 4 categories with the reference of the compass direction in between 3370.30’ to 225.50 follow needle clock’s direction while the three other directions were the westward [WEST], southwest ward [SWST], and northwest ward [NWST]. In order to control the model error we also employed the variables of the air temperature [TEMP] and air humidity. Data collected by surveying to 75 parcels of land belong to HKm member of Mangga Joyo located in Way Kanan Regency. Parameter optimization used Minitab 16. The result suggest, the [WOOD]: (1) will increase significantly around 0.02205(SE=0.01048)m3 for every 100m higher of land elevation, and (2) will decrease significantly around 0.21532(SE=0.07986)m3 which land exposition face to westward than that of eastward. It may be beneficiary for REDD+ implementation under Paris Agreement.
