Today, one of the most important goals for all countries is to get productivity improvement and then achieve economic growth via improving productivity. The aim of this study is to measure total productivity factor and its determinants for soybean farms in the Gorgan County as one of the main soybean production regions in Iran. To this end, first, total factor productivity (TFP) index is calculated by using the Tornqvist index and then, the relationship between TFP and age, experience, education and membership in cooperatives is estimated by the regression approach. This study was done as a survey and data were gathered by using questionnaires from 60 soybean farmers. The results showed that the TFP index varies from 0.37 to 1.82. About 46% of the farms had productivity less than the mean average. Also, experience, education and membership in cooperation factors had a positive and significant effect on TFP. Thus, improving them can help increase soybean production.

The agricultural sector has a special and important place in Iran. In order to make policies and protocols in agricultural sector, it is necessary to better understand the effective factors in growing this sector. In this study, it was attempted to use an appropriate approach to analyze the components of the growth of agricultural products’ value. For this purpose, a non-parametric approach named “multiplicative decomposition method” based on time-series data (1991-92 – 2010-2011) were used to separate value’s growth to parameters such as price [1]growth, cultivation area growth, yield growth and changing cropping pattern and determine the effect of each parameter. The results showed that the growth of agricultural products’ value has had the average annual growth of 16 percent, while the value of the same products in the country showed the average annual growth of 18 percent. Although, the value of agricultural products during the study showed a positive growth, price growth and then cropping pattern were the main reason[2]s for this growth. In sum, these results represent lack of an appropriate improvement in land productivity growth and cropping pattern in Golestan province.
