Characterization of tropical viticulture in the fluminense north and northwest regions

Abstract

Abstract Viticulture is a recent activity in Rio de Janeiro, which has been well adapted to the edaphoclimatic conditions of the north and northwest regions of Rio de Janeiro. The aim of this study was to characterize the main socioenvironmental and technological aspects of grape production in these regions. Data were collected in 2017 and 2018, from the application of questionnaires to 16 grape producers in the regions, for descriptive statistical analysis and preparation of tables and graphs. In both regions small producers are the main investors. Most of them do not participate in associations and have technical assistance in particular. The region has favorable edaphoclimatic characteristics, mainly for the cultivation of rustic grapes, predominantly cultivar ‘Niagara Rosada’. Disease control is carried out in a preventive manner, with eleven applications ranging from sprouting to days before harvest. The regions present more than one harvest per year, having supply in the season and national off season. These results may support information on the characteristics of Rio de Janeiro’s viticulture, direct incentives for the activity and serve as a basis for further research, such as planning programs for grape production areas.
