Abstract

Present study aims at estimation and validation of net primary productivity (NPP) using production efficiency model (PEM), and its possible relationship with tree diversity. The PEM estimates NPP, based on light use efficiency (LUE) and intercepted photosynthetically active radiation (IPAR). Weighted average LUE varied between 0.02 gC/μmol/m2 of PAR (Mixed forest (miscellaneous)) to 0.08 gC/μmol/m2 of PAR (Acacia forest), in growing phase (GP), and 0.0008 gC/μmol/m2 of PAR (Boswellia mixed forest) to 0.023 gC/μmol/m2 of PAR (Acaciaforest) during the senescent phase (SP). The average weighted LUE for tropical dry and Moist deciduous forest (MDF) in GP were 0.05 gC/μmol/m2 of PAR and 0.03 gC/μmol/m2 of PAR, respectively. The average IPAR for different forest types was 2079.58 μmol/m2/s during GP and 1510.58 μmol/m2/s during SP. The PEM based NPP varied between 0.58–275.78 gC/m2/year during GP and 0.43–74.34 gC/m2/year during SP. The PEM based NPP and conventional (ground based) NPP were related with R2 of 0.55. The tree diversity and NPP relationship was observed with R2 of 0.55 at the level of both plot and forest types
