Abstract :
In the present study, using a non-radial Multi-directional Efficiency Analysis (MEA) approach, the productivity changes in potato production were investigated in East Azerbaijan province. The information was collected from published data by the Ministry of Agricultural Jihad included the 16 major potato producing provinces. The results showed the inputs productivity in East Azerbaijan province decreased significantly in all inputs in the 2011-2012 crop year compared to the 2010-2011 crop year. Regarding to efficiency change and technical change, the best situation was for potash fertilizer and seed, respectively. DEA results also confirmed the MEA outputs, so that DEA also showed a negative change in total factor productivity by 86.3% in potato cultivation in the East Azerbaijan province. According to the research findings, with the continuation of the observed trend over the coming years, potato cultivation in the East Azerbaijan province is at risk and it is necessary, simultaneously with management efforts, the changes in the productivity of productive inputs are being measured.
