Most of the literature about the productivity of the agricultural sector has pointed to an inverse relationship between farm size and land productivity, which could induce land reform policy toward raising the productive performance of the entire sector. However, recent results have been contradictory, especially when we take into account the omission of relevant variables and the using more complete measures to represent the productive performance of agriculture. The objective of this research was to determine the relationship between technical efficiency and farm size, considering different classes and area efficiency levels in rural Brazil in 2006. Furthermore, the study also identified the main determinants of productive performance properties when different levels of efficiency are considered. To this end, we used the Stochastic Frontier Approach for productive efficiency scores and the method of Quantile Regression to verify the impact of size, the total financing, irrigation and other variables, considering different levels of efficiency. The data used refer to a special tabulation based on microdata from the agricultural census in 2006. Among the results, it was found that, in fact, partial measures of productivity are inconclusive for the analysis of the impact of farm size on productivity. However, when used the productive efficiency of farms as a measure for total factor productivity, was identified a positive and non-linear relationship between size and efficiency. Moreover, as it was considered more efficient producers groups, this relationship became weaker, indicating that these producers would be less dependent on the land factor. Regarding the determinants of efficiency, access to irrigation technology, technical assistance, presence of storage unit on the farm and association in cooperatives were the variables that most contributed to raise the productive performance, especially in the case of less efficient producers. These results suggest that policies that increase the supply of such resources and services viii would be critical for increasing productivity of farms and reduce inequalities between large and small producers in Brazilian agriculture.
