The purpose of the paper was to test a causal model for finding the factors affecting commercialization intention of Non Timber Forest Products (NTFP’s) using the Theory of Planned Behaviour. NTFP's refers to products generated from forests to be used by human beings, produced by process of harvesting, rather than cutting down woodlands. The study is based on deductive research and uses a descriptive correlation-analysis in terms of methodology. The response population consisted of 187 timber buying and selling households from Keonjhar district of Odisha. A structured questionnaire was used as data gathering tool and the reliability was assessed using Cronbach’s alpha. The impact of the following factors were tested on Commercialization Intention of NTFP's: Attitude (A), Subjective Norm(SN) ,Perceived Behaviour Control(PBC), Government Support(GS) using Structural Equation Modelling. The findings of the study confirmed that Attitude, Subjective Normand Perceived Behaviour Control has a positive and significant impact on Selling Intension of NTFPs whereas, Perceived Behaviour Control has the highest significance. It also showed that more government support is required for the assessment for the intension toward commercialization of NTFPs. The underlying intention of this study is propagation, conservation& promotion of NTFPs, which is currently the need of the hour.
