Wanayasa subdistrict has a wide enough area of potato farming, but its production has fluctuated that caused by the use of inputs. The aims of this research are to determine: (1) the use of inputs, productivity, and income of potato farming; (2) the inputs that affect potato production; (3) allocative efficiency of the inputs of potato farming. The methods used in this research are descriptive statistic and inferential statistic. The research’s location is determined by purposive sampling method, while the sample is determined by simple random sampling with 40 potato farmers. Statistic descriptive is used to determine the use of inputs, productivity, and income. Inputs that affect potato production determined by multiple linear regression with Ordinary Least Square (OLS) method. The allocative efficiency of inputs determined by the ratio of the marginal production value and the price of that inputs. The results show that: (1) The use of inputs isn’t fit to the recommendation; (2) Inputs that affect potato production are land, seed, organic fertilizer, and farmer’s education; (3) Allocative efficiency level of the land is inefficient, seed is not efficient, and organic fertilizer is efficient.
