The study objective was to design and evaluate the agroecological system of an agricultural model with vegetable covers (Luffa cylindrica, Cyclanthera pedata and Mucuna pruriens) associated with tomato plants (Lycopersicum esculentum Mill), Rio Grande and Cherry varieties. The agroecological system is shown with its components of inputs, processes and outputs. The main entrances being solar radiation, rainwater and air as main sources for plant photosynthesis. Components of rooftop agroecosystem are soil, plants, animals and microbes, which form the food pyramid in ecological balance. Production benefits the family in terms of food safety with safe pesticide-free tomatoes. At the same time there is a plant barrier on the roofs to reduce the effects of solar radiation that favors the comfort of the family; in this way the research is framed in the nature of cities with green roofs with their multiple ecological benefits. A new tomato variety obtained by natural crossbreeding between the Cherry and Rio Grande varieties has also been obtained, with medium-sized fruits favorable to the organic tomato market, whose average equatorial diameter is 2.82 ± 0.086 cm, and the average polar diameter 2.47 ± 0.105 cm.
