Productivity is an average measure of the production efficiency. This study was aimed at identifying the soybean productivity in Indonesia, including production and land area. Total Factor Productivity (TFP) was conducted on 100 farmers in Grobogan Regency, Central Java, which is determined by stratified random sampling. The result shows that the productivity value of soybean is 76.8%. This number can potentially increase output as big as 23.3% using the same input factors. The productivity of soybean in 2014 was 2.03 ton/ha and 2015 the number increased by 4.5% became
2.12 ton/ha. The average value of TFP soybean farming in Grobogan regency was 1.007. It indicated a positive progress of productivity by 0.7% in the last two years. The Productivity of Soybean will have an average value of 1.675 ton/hectare for 8 years, i.e. from 2017 until 2024.
