Vegetable farming in the District of East Tarakan used a polyculture cropping pattern, which is an agricultural business that cultivates various types of crops on the same land. By planting more than one type of plant in one field at the same time in one place, there may be differences in the use of inputs which will affect production. This research was conducted in the District of East Tarakan. The purpose of this study, was first, to determine the factors that influence the production of vegetable horticultural food crops, secondly to analyze the factors that influence the overall production of vegetable farming, and thirdly to analyze the partial production factors that most influence the production of vegetable farming. The sampling method was purposive sampling by quota, with a total of 30 farmers as samples. The analysis used is multiple linear regression in logarithmic form with Cobb Douglas production function. Based on the results of the F test simultaneously, the use of land area production factors, seeds, fungicides, insecticides, shrimp shell fertilizers, chicken manure, and labor from mustard greens, pakcoy, kale, spinach, and celery gave a very real effect. Based on the value of the determinant coefficient R2 for the five varieties, it was found that these variables can affect the production of mustard kumala by 93%, pakcoy by 86.7%, kale by 88.5%, spinach by 77.7%, and celery by 92.9%. In mustard greens, the independent variables that have a very significant effect are seeds (X2), shrimp shell fertilizer (X5), pakcoy vegetables are land area (X1), insecticides (X4), shrimp shell fertilizers (X5), kale is a land area (X1), shrimp shell fertilizer (X5), spinach is a land area (X1), insecticide (X4), shrimp shell fertilizer (X5), chicken manure fertilizer (X6), celery is a land (X1), shrimp shell fertilizer (X5), chicken manure fertilizer (X6).
