摘要

Gilan province has 35 percent of Iran's rice production and 42 percent of rice acreages. In this study Total Factor Productivity of 3 rice varieties was investigated and compared by using Tornqvist-Tiel index. Requested data set were obtained by using questioner and interviewing with 542 individual farmers of Gilan province rice farming society. Results revealed that hybrid variety had the most partial and total factor productivity by mean. Total factor productivity is 1.052 percent by mean in hybrid variety which could be reached to 1.4 percent by treating farmers.
