SUMMARY:

The world production and consumption of citrus fruits, including tangerine, showed a strong increase in the 1990s, when production expanded rapidly, with Brazil reaching fourth place in world production. In the state of Rio de Janeiro, with the expansion of tangerine plantations from the coastal and metropolitan regions to the mountain region in the 2000s, due to the good adaptation of the species to the climate, it was noticed the interest of the farmer in the municipality of São José do Vale do Rio Preto (RJ) in the cultivation of this fruit in local sloping areas. Thus, the demand for technical information related to management focused on local edaphoclimatic conditions grew. In the absence of options to solve phytosanitary and nutritional problems, farmers turn to industrial agrochemicals. To reverse this trend, it is necessary to adopt agroecological-based technologies for the cultivation of Poncã tangerines in the municipality, which guarantee the maintenance of adequate levels of productivity and reduce the external dependence of the farms on the use of inputs with high ecotoxicological potential. In order to do so, in the work with the farmers, the various demands and difficulties of the Poncã tangerine production activity were investigated, and made it possible to establish guidelines for the construction of production strategies in balance with the environment. The purpose of this dissertation is to carry out case studies in the aforementioned municipality, based on data collection related to the cultivation areas and the systematization of the information collected for the preparation of informative material. With this information, we will seek to meet the demands of farmers from the formulation, in a participatory way, of didactic instruments to support the dissemination of agroecological strategies for the local cultivation of Poncã tangerine. Actions were proposed to control pests and diseases and mechanisms to identify nutritional disorders. Through the identification of the planted areas, it was possible to produce a map containing the distribution of Poncã tangerine plantations in the municipality of São José do Vale do Rio Preto (RJ) and indicating the orchards that maintained agroecological practices. Through the results of the parameters surveyed, it was possible to establish a relationship between the incidence of pests and diseases below the level of damage with the moderate use of pesticides, reducing the imbalance of the trophic chain in the environments in which the Poncã tangerine is inserted. Furthermore, it was possible to verify that adequate attention is not given to soil management, which, when conducted with conservationist practices, can promote the best balance of plants and increase production.
