This paper deals with organic vegetable production planning by which the farmer has to determine the cropping schedules for each land parcels to maximize land parcels occupation. There is more than one variety of crops to be planted and some of these crops are included in one type of botanical family. The farmers do not use pesticide, instead, they use crop rotation in the planting process to minimize pest attack to obtain optimal yields. They must consider the ecological constraints in which farmers must determine the crop sequence and in which land parcel each vegetable must be planted in firm lands by following the rules of crop rotation. The crop included in one botanical family should not be planted sequentially in the same land parcel. We propose a linear programming model to develop organic vegetable production. The decision variable in this study is binary, 1 if one of the crops is cultivated during period j at land parcels k, 0 otherwise. The result show that the cropping schedules of each crop in each land parcel are in one rotation period. To evaluate the performance of the model, numerical experiments using real-world data were performed.
