| Summary: | Banten Province on the 2019 year has to harvest area of corn was 66,356 ha with 331,865.38 tons production and the highest production in Pandeglang Regency. The purpose of this study was: 1) Knowing the pattern of corn farming in Banten Province, 2) Knowing the factors of production that affect corn production. 3) Knowing the cost factors that affect the cost of corn production. The analytical method used multiple linear analysis of the Cobb Douglas production and cost function. The results of the study were: 1) The planting pattern of corn was corn-corn - fallow. Dominant varieties were NK-212 (75.8%), Bima (12.1%) and BISI-18 (12.1%). Average productivity in RS 2018/2019 was 3.44 tons of dry shelled ha-1. The B/C ratio is 0.7, it’s mean financially not profitable.2) Factors that significantly affect corn production were: number of seeds, amount of manure, and number of tractors rent, and variety dummy. A cumulative elasticity value of 1.0 means corn farming was efficient. 3) Factors that significantly influence the cost of production were liquid herbicide prices and human labor costs. Increasing corn productivity still needs to be done with the use of proportional farming inputs.
