Limited land owned by farmers which in the same land farmers grow 2 types of maize with different time, namely sweet corn and hybrid corn within 1 year. In the dry season farmers grow hybrid corn and in the rainy season farmers grow sweet corn. Farmers capital for purchase production facilities, especially for the purchase of seeds, fertilizers, and medicines whose prices are getting higher and higher, in addition to the price of corn and hybrid corn which always increases fluctuations, and in terms of cost and time of hybrid corn is higher than sweet corn. This will have an impact on income obtained by farmers. Sampling in this study was carried out by proportional random sampling.
