This article briefly describes the symptoms associated with water stress at different phenological phases (bud break to flowering, flowering to fruit set, fruit set to veraison, veraison to harvest and harvest to dormancy) and discusses considerations regarding amount, timing and method of vineyard irrigation. A summary is also given of research aimed at evaluating the benefits and problems associated with irrigation-based control of grapevine growth. In the studies initiated in 1987 in a 64-acre drip-irrigated orchard at Paterson, Washington, USA, 4 different irrigation schedules were tested. A satisfactory crop was achieved with 300-500 mm of water per year, including a postharvest irrigation to bring the soil to a moisture level which would protect the root system from cold injury. The only problem with using deficit irrigation as a management tool was a yield loss when stress became excessive.
