CHARACTERIZATION OF TOMATO (Lycopersicum esculentum Mill.) CROPPING SYSTEM IN THE STATE OF JALISCO, MÉXICO

Cropping systems of tomatoes in the State of Jalisco, Mexico, were characterized variables useful to explain the technical and economic problems of these systems were prioritized. Five producing regions were identified: Sayula, La Cienega, Sierra de Amula, Costa Sur, and Zapotlan El Grande. A stratified random sampling was performed and face to face structured interviews with tomato producers were applied. The questionnaire included sections to record the sociodemographic characteristics, production performance, technology, food safety and production marketing system. The characterization of production systems was performed using the technological variables: Type of protection, cultivated surface, type of irrigation system, wadding (mulch), input use, yield, production costs, market and food safety. Systems were classified in three groups: open field, greenhouse and mesh shade production system, whit two subsystem organic production with mesh shade and greenhouse without mulch. 84% of producers use an open field system, 8% produce in greenhouse, 4% use the mesh shade system and the remaining 4% produce with any combination of the above systems. The main cultivated variety is Saladette. Productivity of each system is determined by the level and type of technology. All producers use drip irrigation systems and 96% use plastic mulching (wadding). 90% of producers allocate its production through a broker and 10% sell directly to wholesale markets; the main broker usually is the person who owns the warehouse. Weather conditions, pests and diseases are the main factors affecting negatively the productivity and yield of the crop, with negative economic impact on farmers.
