Farm production and efficiency have always been a primary research question for researchers and agricultural organizations of Pakistan. Meta-analysis in present study provides the statistical efficiency analysis as well as statistical information regarding methodological, regional and crop specific influences on farm sector of Pakistan. The data rely on the published research papers on efficiency analysis of Pakistan's farm sector from 1971 to 2014. Three models separately estimated included methodological model, crop specific model and provincial model. These models incorporated the impact of methodological variables, crop specific variables and regional variables impact on Mean Technical Efficiency Scores (MTES), such as parametric, non-parametric techniques, functional forms, data types, production technology dummies and variable size parameter. The analysis revealed the overall technical efficiency of Pakistan's farm sector as 73%. The results from meta-analysis clearly indicated that farm sector in Pakistan is way behind its optimum potential level. Hence there is sufficient room for improvement. To this end, government should be well-designed to evaluate the misdirected growth policies in farm sector of Pakistan.
