IRRIGATION MANAGEMENT ON WINE GRAPES IN THE TROPICAL ZONE

L.H. Bassoi
The wine grape production in the tropical zone, and in particularly in the Brazilian semi-arid region, is dependent on irrigation practice due to insufficient rainfall and irregular distribution over three to four months in a year. Drip irrigation systems as well as vertical trellis system are predominant for wine grapes in this region. Some of the irrigation management guidance in practice in the field is based on previous experience and knowledge from other regions with some climate similarities, like USA (California) and Australia. As a relatively new crop in the Brazilian semi-arid region, first research results about irrigation scheduling or strategies in wine grapes are recent. Irrigation strategies as deficit irrigation, regulated deficit irrigation and partial rootzone drying have been evaluated. Therefore, research efforts in the Brazilian semi-arid region should be addressed to water consumption by scion/rootstock varieties, as well as ecophysiological behavior, berry and wine characteristics influenced by water management, according to local edaphic and climatic conditions.
