Demonstration of plant-based irrigation on wine-grape performance and quality in three climatically different regions

Project number: FShip Water 2
Project leader: Lategan, E
The objective of this study is to develop guidelines based on grapevine water status for wine grape irrigation. In order to apply the minimum irrigation requirement, sound irrigation scheduling practices are essential. This project will be conducted in the form of demo plots in established commercial vineyards, in three climatically different areas (Stellenbosch, Breedekloof and Olifants River). Irrigation scheduling will be done based on plant water potential values based on previous research and compared to the grower’s normal scheduling practice.
